New Features in JUNOS Release 10.1 for M Series, MX Series, and T Series Routers
The following features have been added to JUNOS Release 10.1. Following the
description is the title of the manual or manuals to consult for further information.
Class of Service
■
Intelligent oversubscription service support (MX Series routers with Trio
MPC/MIC interfaces)—Arriving packets are assigned to one of two traffic classes
(control and best-effort) based on their header types and destination MAC address.
This allows for lower priority packets to be dropped more intelligently when
oversubscription occurs. Only packets mapped to queue 3 are marked as control
packets. Protocols such as telnet, FTP, and SSH that are mapped to queue 0 are
classified as best-effort. No configuration is necessary, but the queue assignments
can be altered with a multifield classifier.
[Class of Service]
■
CoS aspects of the MPC/MIC (MX Series routers with Trio MPC/MIC
interfaces)—Cover all aspects of CoS configuration for this hardware combination.
Support includes shaping rates at the queue level, configurable bandwidth profiles
with percentages, dynamic bandwidth allocation among different services,
scheduler node scaling, and delay buffer allocation. To configure, include the
relevant statements at the [edit class-of-service] hierarchy level and apply them
if necessary at other hierarchy levels such as the [edit interfaces] hierarchy level.
[Class of Service, Network Interfaces]
■
Per-priority shaping (MX Series platforms with Trio MPC/MIC
interfaces)—Enables you to configure a separate shaping rate for each of the
five priority levels so that higher priority services such as voice and video do not
starve lower priority services such as data. To configure, include the
shaping-rate-(excess | priority)-level rate [ burst-size burst ] statement at the [edit
class-of-service traffic-control-profiles tcp-name] hierarchy level and apply the traffic
control profile at the [edit interfaces] hierarchy level.
[Class of Service]

■
JUNOS Software Release Notes for Juniper Networks M Series Multiservice Edge Routers, MX Series Ethernet Service Routers,
and T Series Core Routers
■
Distribute excess bandwidth among different services for a subscriber (MX
Series routers with Trio MPC/MIC interfaces)—Service providers often use
tiered services that must carry excess bandwidth as traffic patterns vary. By
default, excess bandwidth between a configured guaranteed rate and shaping
rate is shared equally among all queues, which might not be optimal for all
subscribers to a service. You can control the distribution of this excess bandwidth
with the excess-rate statement. To configure the excess rate for a traffic control
profile, include the excess-rate statement at the [edit class-of-service
traffic-control-profiles tcp-name] hierarchy level and apply the traffic control profile
at the [edit interfaces] hierarchy level. To configure the excess rate for a queue,
include the excess-rate and excess-priority statements at the [edit class-of-service
scheduler scheduler-name] hierarchy level.
[Class of Service]
■
Scheduler node scaling (MX Series routers with Trio MPC/MIC interfaces)—The
hardware supports multiple levels of scheduler nodes. In per-unit-scheduling
mode, each logical interface (unit) can have four or eight queues and has a
dedicated level 3 scheduler node. The logical interfaces share a common level
2 node (one per port). In hierarchical-scheduling mode, a set of logical interfaces,
each with four or eight queues, has a level 2 CoS profile and one of its logical
interface children has a level 3 CoS profile. To better control system resources
in hierarchical-scheduling mode, you can limit the number of hierarchical levels
in the scheduling hierarchy to two. In this case, all logical interfaces and interface
sets with CoS profiles share a single (dummy) level 2 node, thereby increasing
the maximum number of logical interfaces with CoS profiles (the interface sets
must be at level 3). To configure scheduler node scaling, include the
maximum-hierarchy-levels statement at the [edit interfaces xe-fpc/pic/port
hierarchical-scheduler] hierarchy level. The only supported value is 2.
■
Forwarding-class aliases (M320 and T Series routers)—Enable you to configure
up to 16 forwarding classes and 8 queues, with multiple forwarding classes
assigned to single queues. To configure, include the class and queue-num
statements at the [edit class-of-service forwarding-classes] hierarchy level.
[Class of Service]
■
VLAN shaping on aggregate devices (MX Series routers with Trio MPC/MIC
interfaces)—VLAN shaping (per-unit scheduling) is supported on aggregated
Ethernet interfaces when link protection is enabled on the aggregated Ethernet
interface. When VLAN shaping is configured on aggregate Ethernet interfaces
with link protection enabled, the shaping is applied to the active child link. To
configure link protection on aggregated Ethernet interfaces, include the
link-protection statement at the [edit interfaces aex aggregated-ether-options]
hierarchy level. Traffic passes only through the designated primary link. This
includes transit traffic and locally generated traffic on the router. When the
primary link fails, traffic is routed through the backup link. You also can reverse
traffic, from the designated backup link to the designated primary link. To revert
back to sending traffic to the primary designated link when traffic is passing
through the designated backup link, use the revert command; for example, request
interfaces revert ae0. To configure a primary and a backup link, include the
primary and backup statements at the [edit interfaces ge-fpc/pic/port
gigether-options 802.3ad aex] hierarchy level or the [edit interfaces xe-fpc/pic/port
fastether-options 802.3ad aex] hierarchy level. To disable link protection, delete
■

the link-protection statement at the [edit interfaces aex aggregated-ether-options
link-protection] hierarchy level. To display the active, primary, and backup link
for an aggregated Ethernet interface, use the operational mode command show
interfaces redundancy aex.
■
Re-marking of MVPN GRE encapsulation DCSP at ASBR (MX Series routers
with Trio MPC/MIC interfaces)—Enables you to configure DSCP marking for
GRE encapsulated packets that aligns with the service provider core CoS policy
for an MVPN. To configure, include the DSCP rewrite-rule dscp dscp-rule-name
with the values at the [edit class-of-service] hierarchy level and then apply the
rewrite rule to the core-facing multicast interface at the [edit class-of-service
interfaces] hierarchy level.
[Class of Service]
■
PD-5-10XGE-SFPP, 10-port 10-Gigabit Ethernet (Type 4) PIC (T640, T1600,
and TX Matrix routers with G-FPC4, ST-FPC4, and ST-FPC4.1)—Supports a
WAN bandwidth of 100 Gbps in addition to the following features:
■
Intelligent handling of oversubscribed traffic
■
Line rate operation on up to five 10-Gigabit Ethernet ports
■
Tap features, such as flexible encapsulation, source address (SA) MAC
learning, MAC accounting, and MAC policing
■
Stacked virtual LAN (VLAN) tag and VLAN rewrite functionalities
[Network Interfaces, Class of Service, PIC Guide]
■
Intelligent oversubscription services (MX Series with 16-port 10-Gigabit
Ethernet MPC with SFP+)—The 16-port 10-Gigabit Ethernet Modular Port
Concentrator (MPC) is an oversubscribed configuration. Consequently, it is
necessary to protect control traffic over best-effort traffic as soon as packets
enter the line card. To do this, packets entering the line card are assigned a
preclassifier control traffic class according to the header types (such as destination
MAC addresses, and Layer 4 ports) in the packet. The preclassifier provides a
good way to classify and queue important control traffic in a different high-priority
queue from that used for best-effort traffic.
The preclassifier (control or best effort) is assigned prior to packets being accepted
into the initial stream and is used by the line card as an early designation (before
any class-of-service configuration is applied). When oversubscription occurs,
control traffic will be queued separately and should not be subject to any dropped
packets.
The Layer 2 protocols supporting the preclassifier are:

present in the JUNOS Software. However, with this line card, the value range
permitted is modified from 0, to 0 through 63. To include DSCP as the action
of a filter rule, include the dscp value parameter at the [edit firewall filter
filter-name] hierarchy level.
■
To fully leverage the features offered through the new chipset on the line
card, include the enhanced-hash-key option at the [edit forwarding-options]
hierarchy level.
[Class of Service]
■
11
■
IEEE 802.1ak-2007 MVRP (MX Series routers)—The Multiple VLAN Registration
Protocol (MVRP) is a standards-based Layer 2 network protocol used among
switches to dynamically share and update VLAN information with other bridges.
VLAN information exchanged includes:
■
The set of VLANs that currently have active members
■
The ports through which the active members can be reached
To operate MVRP, edge ports should have the static VLAN configuration. The
edge ports will not be configured for MVRP. MVRP is only enabled on the
core-facing trunk ports where no static VLANs are configured.
To configure MVRP, include the mvrp statement and desired options at the [edit
protocols] hierarchy level.
[Class of Service]
■
Elevated packet drops during oversubscription (MX Series routers with Trio
MPC/MIC interfaces)—During periods of oversubscription, the WRED process
drops more packets than expected from relatively full queues. There is no
configuration for this feature, which transparently applies scaling to
oversubscribed queues.

Root System Domain (RSD) configuration of logical interface filters on shared
interfaces (JCS1200 platform)—Enables Root System Domain (RSD) configuration
support for logical interface filters on shared interfaces. In previous releases,
logical interface filters were configured on each Protected System Domain (PSD).
This release supports configuration on the RSD.
To configure a logical interface filter on the RSD, apply the firewall filter to the
logical interface on the shared interface by including the filter output filter-name
statement at the [edit interfaces interface-name unit logical-unit-number] hierarchy
level on the RSD.
Filtering is performed on the PSD, but logical interface filters configured on the
RSD are applied automatically by the PSD. Filters configured on the RSD can
co-exist with filters configured on the PSD. Counter statistics related to PSD
filtering are available on the RSD.

Two new AC power supply modules (AC Power Entry Module 10kW US and
AC Power Entry Module 10kW EMEA) in chassis—The JUNOS Software now
supports two new AC power supply modules on T640 and T1600 routers: AC
Power Entry Module 10kW US and AC Power Entry Module 10kW EMEA (for
U.S. and EMEA markets, respectively). The two Power Entry Modules (PEMs)
cannot interoperate and the JUNOS Software reports an alarm when they do.
The show chassis environment pem command output will show AC Input: status
instead of DC Input: status and the Temperature will show the actual temperature
reading. Two new power supply descriptions, US and EMEA, are added to
distinguish the new modules from existing ones in the output of the show chassis
hardware command output.

identification field in the outer IP header of packets encapsulated with generic
routing encapsulation (GRE), so that reassembly of the packets is possible after
fragmentation. The previous CLI constraint check that requires you to configure
either the clear-dont-fragment-bit statement or a tunnel key with the
allow-fragmentation statement is no longer enforced. There are no associated
changes to the CLI statements or operational mode commands.
NOTE: For other routers, the earlier configuration constraint check still holds.

packets contain the correct input and output interface SNMP index, the source
and destination AS numbers, and the source and destination mask.
There are two ways to verify the sampled packets. The first is to include the file
sampled statement at the [edit forwarding-options sampling traceoptions] hierarchy
level and the local dump statement at the [edit forwarding-options family inet output
flow-server server] hierarchy level, and check the sampled file using the tail –f
/var/tmp/sampled command from the router shell. The second is to export and
verify the sampled packets to the flow-server.

New 4-port Channelized OC12 Enhanced Intelligent Queuing (IQE) type 3
PIC (M Series and T Series routers)—Provides increased channelization and an
improved QoS model; with channelization capabilities and scaling that make it
ideal for edge aggregation.
Improved QoS functionality supports policing based on DSCP/IPPREC/EXP, five
priority levels, two shaping rates (CIR and PIR), option to use shared scheduling
on set of logical interfaces, DSCP rewrite on ingress, and configurable delay
buffers for queueing. The QoS capabilities provide service differentiation for
service providers.
The interface configuration syntax of existing IQ PICs is retained, but
configuration limits are changed to match the augmented capabilities of IQE
PICs.
All functionality available on the 4-port Channelized OC12 IQ Type 2 PIC is
supported by this PIC.
■
Enhanced Intelligent Queuing (IQE) PICs add support for T3 and T1

The JUNOS Software supports T1 and CT1 interface types under CAU4. To
configure T1 and CT1 interfaces under CAU4, use the t1 and ct1 statements at
the [edit interfaces cau4-fpc/pic/port:unit partition number interface-type] hierarchy
level.
With T1 and CT1 interface configurations under CAU4 interfaces, you can
configure a maximum of 84 T1 or CT1 inerfaces. However, the partition range
under CAU4 interfaces was previously restricted to from 1 to 63. This range has
increased to from 1 to 84 for T1 and CT1 interfaces.
The JUNOS Software supports T1, CT1, T3, and CT3 interfaces under Channelized
AU4 partitions. To configure T1, CT1, T3, and CT3 interfaces under Channelized
AU4, use the ct1 and t1 statements at the [edit interfaces cau4-fpc/pic/port:unit
partition partition-number] hierarchy level or the ct3 and t3 statements at the [edit
interfaces cau4-fpc/pic/port:unit partition number interface-type] hierarchy level.

MPLS Applications
■
Static LSPs at the ingress router—You can now configure a named static LSP
at the ingress router. This feature allows you to configure multiple static LSPs
between two specific routers. It is not necessary to configure unique names for
static versus dynamic LSPs (a static LSP could have the same name as a dynamic
LSP configured on the same router). This feature also allows you to configure a
single-hop static LSP by specifying either an explicit null label or no label.
To configure a static LSP on an ingress router, include the ingress statement at
the [edit protocols mpls static-label-switched-path static-lsp-name] hierarchy level.
You must also configure the to and next-hop statements at the [edit protocols mpls
static-label-switched-path static-lsp-name] hierarchy level. You can optionally
configure the push statement. If you configure the push statement, you must
specify a non-reserved label in the range of 0 through 1,048,575.
To display information about ingress static LSPs, issue the show mpls lsp static
ingress command. To display routing table entries corresponding to ingress static
LSPs, issue the show route table inet.3 command or the show route next-hop
next-hop-ip-address static-label-switched-path static-lsp-name command.
[MPLS, Routing Protocols and Policies Command Reference]
■
Static LSPs at the transit router—You can now configure a named static LSP
on a transit router. To configure a transit static LSP, include the transit statement
at the [edit protocols mpls static-label-switched-path path-name] hierarchy level
and include the next-hop statement at the [edit protocols mpls
static-label-switched-path static-lsp-name] hierarchy level. You must also configure
either the pop or the swap statement at the [edit protocols mpls
static-label-switched-path static-lsp-name transit] hierarchy level. If you configure
the swap statement, you must specify a non-reserved label in the range of 0
through 1,048,575.
The transit static LSP is added to the mpls.0 routing table. You should configure
each static LSP using a unique name and at least a unique incoming label on the
router. Each transit static LSP can have one or more incoming labels configured.
If a transit LSP has more than one incoming label, each would effectively operate
as an independent LSP, meaning you could configure all of the related LSP
attributes for each incoming label. The range of incoming labels available is
limited to the standard static LSP range of labels (1,000,000 through 1,048,575).
To verify that a static LSP has been added to the routing table, issue the show
route table mpls.0 command.
[MPLS]
■
Bypass static LSPs—You can now configure a named bypass static LSP for ingress
and transit static LSPs, to be used if the primary LSP fails. To configure a bypass
static LSP, include the bypass statement at the [edit protocols mpls
static-label-switched-path path-name] hierarchy level. You must also configure the
to and next-hop statements at the [edit protocols mpls static-label-switched-path
static-lsp-name bypass] hierarchy level. You can also configure link and node
protection for static LSPs. If you configure both link and node protection for the
static LSP and the primary link fails, the node protection feature is preferred.
■
21
[MPLS]
■
Static LSP revert timer—You can now configure a revert timer for ingress and
transit static LSPs. After traffic has been switched to a bypass static LSP, it is
typically switched back to the primary static LSP when it comes back up. There
is a configurable delay in the time (called the revert timer) between when the
primary static LSP comes up and when traffic is reverted back to it from the
bypass static LSP. This delay is needed because when the primary LSP comes
back up, it is not certain whether all of the interfaces on the downstream node
of the primary path have come up yet. The delay range is from 0 through 65,535
seconds and is configurable at each interface. If you configure a value of 0, traffic
is never automatically reverted to the primary LSP, even if it does come back
up. The only exception is if the bypass LSP goes down. The default value is 5
seconds. To configure the revert timer for an interface, include the
protection-revert-time statement at the [edit protocols mpls interface interface-name
static] hierarchy level. You can display the revert timer value for an interface
using the show mpls interface detail command.
[MPLS]
■
Static LSP traceoptions—You can now configure the traceoptions statement to
trace messages related to ingress and transit static LSPs by including the static
flag at the [edit protocols mpls traceoptions flag] hierarchy level.
[MPLS]
■
Static LSP statistics—You can now display statistics related to MPLS static LSPs
by issuing the show mpls static-lsp statistics command and the monitor static-lsp
lsp-name command. The show mpls static-lsp statistics command includes the
following options: ingress, transit, bypass, and name static-lsp-name. This command
displays the packet count and byte count for the static LSP. You can clear the
statistics for static LSPs by issuing the clear mpls static-lsp statistics command.
You can also log the static LSP statistics to a file by specifying a file for the MPLS
statistics statement. You can configure this file using the set protocols mpls
statistics interval interval file filename command.

Border Gateway Function (BGF) RTCP XR reporting—Provides support for the
H.248 RECRTCPXR (Received RTCP Extended Reporting) and RECRTCPXRBM
(Received RTCP XR Burst Mode) reporting packages. The RECRTCPXR package
defines properties and statistics that provide extended quality-of-service metrics
received from the gateway controller. The RECRTCPXRBM package defines
properties and statistics that provide burst metrics received from the gateway
controller. Report data is available to the BGF when the gateway controller sends
the relevant XR reporting packets and RTCP monitoring is active. Not all gateway
controllers send the extended reporting packets. When XR packets are not
received, all XR fields are displayed as 0s (zeroes).
You can use the following existing command to display the RECRTCPXR and
RECRTCPXRBM report fields for a given gate-id: show services pgcp gate
gateway-name statistics gate-id gate-id.

Integrated Multi-Services Gateway (IMSG) media release—Enables the IMSG
SIP function to release media resources when handling calls between two entities
in the same media realm (the virtual interface specified in the PGCP
configuration). When the new call usage policies for both entities allow media
release, media resources are shared instead of being reserved for both entities.
This improves the utilization of media resources and prevents latency.
To configure media release, enter the media-release statement at the [edit services

Routing Policy and Firewall Filters
■
New MPLS firewall filter match conditions (T Series routers)—The JUNOS
Software now supports filtering MPLS-tagged IPv4 packets based on IP parameters
for up to five MPLS stacked labels.
To configure the filter match conditions for an MPLS family based on IP
parameters, include the from statement at the [edit firewall family family-name
filter filter-name term term-name] hierarchy level:
from {

NOTE: New filter match conditions are applicable only for MPLS-tagged IPv4 packets.
MPLS-tagged IPv6 packets are not supported by this filter.

BGP support for MDT-SAFI updates without a route target—By default, the
JUNOS Software requires MDT-SAFI updates to have a route target attached.
Some vendors do not support attaching route targets to the MDT-SAFI updates.
For interoperability with these vendors, the JUNOS Software allows importing
MDT-SAFI updates without a route target being attached. The MDT-SAFI is
imported if the MDT default address in the MDT-SAFI prefix matches the MDT
default address configured within the routing instance.
To configure the MDT default address, include the group-address group-address
statement at the [edit routing-instances routing-instance-name provider-tunnel
pim-ssm] hierarchy level.

■
Distributed periodic packet management support for aggregate
interfaces—Extends support for the Bidirectional Forwarding Detection (BFD)
protocol to use the periodic packet management daemon (PPMD) to distribute
IPv4 sessions over aggregate interfaces. PPMD automatically runs on the Routing
Engine and the Packet Forwarding Engine. To disable PPMD on the Packet
Forwarding Engine only, include the no-delegate-processing statement at the [edit
routing-options ppm] hierarchy level. Only IPv4 BFD sessions over aggregate
interfaces are supported. PPMD does not support IPv6 BFD sessions over an
aggregate interface or MPLS BFD sessions over an aggregate interface.
[Routing Protocols]
■
PIM join suppression support—Enables a router to defer sending join messages
to an upstream router when identical join messages are sent on the same
multiaccess network. This improves scalability and efficiency by reducing the
number of identical messages sent to the same router.
This feature is useful when there are a large number of routers on a multiaccess
network that will be receiving traffic for a particular multicast group. Suppressing
joins at each router saves bandwidth and reduces heavy processing at upstream
routers.
PIM join suppression can be implemented per multiaccess interface and per
multicast group. It is only needed on downstream routers, and does not need to
be implemented on upstream routers in order for it to work.
A tracking bit field on the LAN prune delay hello option is used in the CLI to
enable join suppression for downstream routers. By default, the tracking bit is
set to 1 and PIM join suppression is disabled. This is the default behavior for
JUNOS Release 10.0 and earlier for Juniper Networks routers. With join
suppression disabled (T-bit=1), a downstream receiving router will send join
messages even if it receives identical joins for the same upstream router, as long
as no other router in the network has join suppression enabled. When the tracking
bit is set to 0 for at least one neighbor on this interface, join suppression is
enabled, and the receiving router will defer sending identical joins. Use
reset-tracking-bit in the CLI to enable join suppression.
When an upstream router receives a join message, its behavior is independent
of the value of the T-bit in the hello option. When join suppression is triggered,
a timer is activated and all sending of joins is deferred for the length of time
24
■
specified by the timer. This is a random timer with value ranges between 0 to
Max Override Interval. The timer is reset each time join suppression is triggered,
and the defer period is dependent on other settings in the LAN prune delay,
including propagation-delay and override-interval.
Use the show protocols PIM command to see if the reset-tracking-bit is present,
indicating that the T-bit has been changed to 0 and PIM join suppression is
enabled.
[Multicast, Routing Protocols and Policies Command Reference]
■
Improve IGMPv3 snooping performance using bulk updates 1a3,14—Whenever
an individual interface joins or leaves a multicast group, a new next-hop entry
is installed in the routing table and the forwarding table. This can require a lot
of processing time when the frequency and number of IGMP join and leave
messages are high.
A new configuration statement can be used to accumulate outgoing interface
changes and perform bulk updates to the routing table and forwarding table.
This reduces the processing time and memory overhead required when processing
join and leave messages, thus improving scalability.This is useful for applications
such as Internet Protocol television (IPTV), in which users changing channels
can create thousands of interfaces joining or leaving a group in a short period
of time.
To enable bulk updates of join and leave messages, include the next-hop-hold-time
statement and specify the number of milliseconds to wait before processing the
messages. The next-hop-hold-time statement can be configured at the [edit
routing-instances routing-instance-name] hierarchy level. The hold time can be
configured from 1 to 1000 milliseconds. The routing instance must be of type
VPLS or virtual-switch.
If the next-hop-hold-time statement is deleted from the router configuration, IGMP
bulk updates are disabled. The configuration of the next-hop-hold-time statement
can be verified using the show multicast snooping route command.

This feature is useful in the following scenarios:
■
Customer sources and rendezvous points (RPs) are located only in the hub

■
Customer sources are located only in spoke sites and customer receivers are
located only in hub sites.

FlowTapLite enhancements—Extend support for interception of IPv6 packets
on MX Series, M120, and M320 routers. For IPv6, the global filter taps packets
from the default IPv6 routing table and does not tap packets from other VRFs.
To tap packets from other VRFs, you can install separate VRF filters. For IPv4,
the global filter intercepts all IPv4 packets irrespective of the VRF. The limit for
filters remains 3000, which is now shared between IPv4 and IPv6. For example,
you can install 3000 IPv4 filters or 3000 IPv6 filters, or a combination of both
that totals 3000. You cannot install 3000 IPv4 filters and 3000 IPv6 filters.
No new statements are required to configure these enhancements. However,
whether you use IPv6 flow tapping or not, you must include the family inet6
statement at the [edit interfaces vt-fpc/pic/port unit logical-unit-number] hierarchy
level.

DHCP subscriber VLANs
PPP logical interfaces
PPPoE subscriber VLANs
PPP connections (logical interfaces) are supported in a range of configurations.
For example, 63,999 PPP connections per chassis are supported when all
subscribers are configured on the same VLAN. In this case, 63,999 pp0 interfaces
are configured under the same VLAN logical interface and the one remaining
logical interface is consumed for the single VLAN.
At the other extreme, when you configure each subscriber on a separate VLAN
(using stacked VLANs), up to 32,000 PPP connections per chassis are supported.
28
■
In this case, each subscriber connection consumes two logical interfaces: one
for the VLAN logical interface and one for the pp0 logical interface.
The M120, M320, and MX Series routers support a maximum of 2000 different
dynamic profiles per chassis. [Subscriber Access]
■
Support for dynamic CoS for subscriber interfaces on Trio MPC/MIC interfaces
(MX Series routers)—Enables you to configure dynamic CoS for subscriber
interfaces on Trio MPC/MIC interfaces that are now available on MX Series routers.
In earlier releases, dynamic CoS was supported on EQ DPCs only.
To configure dynamic CoS on Trio MPC/MIC interfaces, you must enable the
hierarchical scheduler for an interface at the [edit interfaces] hierarchy level. You
can then configure dynamic CoS parameters at the [edit dynamic-profiles
profile-name class-of-service] hierarchy level. The CoS parameters are dynamically
applied to subscriber’s services when they log in or change services.
Trio MPC/MIC interfaces support CoS for the following interface types: static
VLAN, demux, static and dynamic PPPoE, and aggregated Ethernet subscriber
interfaces.
In this release, hierarchical CoS for aggregated Ethernet interfaces is supported
on the Trio MPC/MIC product when a static VLAN configured over the aggregated
Ethernet interface. It is not supported for static or dynamic demux subscriber
interfaces configured over aggregated Ethernet.

■
Support for CoS on dynamic PPPoE subscriber interfaces (MX Series
routers)—Enables you to configure CoS for dynamic PPPoE subscriber interfaces
on Trio MPC/MIC interfaces available on MX Series routers and the Intelligent
Queuing 2 (IQ2) PIC on M120 and M320 Series routers.
In earlier releases, only static CoS was supported for static PPPoE subscriber
interfaces configured on IQ2 PICs on M120 and M320 Series routers.
To configure CoS for a dynamic PPPoE interface, configure the shaping and
scheduling parameters at the [edit dynamic-profiles profile-name class-of-service]
hierarchy level. You then attach the traffic control profile to the dynamic PPPoE
interface by including the output-traffic-control-profile profile-name statement at
the [edit dynamic-profiles profile-name class-of-service interfaces
$junos-interface-ifd-name unit $junos-underlying-interface-unit] hierarchy level.
When the subscriber logs in, PPP supplies pp0 as the $junos-interface-ifd-name
variable, and supplies the PPPoE logical interface number for the
$junos-underlying-interface-unit variable.

■
Support for IPv6 for dynamic subscriber services (MX Series routers)—Enables
you to configure IPv6 addressing and prefixes for dynamic subscriber services.
In earlier releases, dynamic subscriber services supported IPv4 addressing only.
You can now configure both IPv4 and IPv6 addressing in the same dynamic
profile to grant access and services to IPv4 and IPv6 subscribers.
In this release, IPv6 addressing is supported for static and dynamic VLAN
subscriber interfaces and dynamic demux subscriber interfaces.
■
29
To enable IPv6 addressing for a static VLAN subscriber interface, include the
family inet6 statement at the [edit dynamic profiles profile-name interfaces
interface-name unit logical-unit-number] hierarchy level.
To enable IPv6 addressing for a demux subscriber interface, include the family
inet6 statement at the [edit dynamic profiles profile-name interfaces demux0]
hierarchy level. To enable an IPv6 source address for the interface, specify the
new $junos-subscriber-ipv6–address predefined variable with the demux-source
statement at the [edit dynamic profiles profile-name interfaces demux0 unit
$junos-interface-unit family inet6] hierarchy level. The values for this variable are
supplied to the interface by DHCP when the subscriber logs in.
This feature enables you to configure dynamic, classic, and fast update firewall
filters for IPv6 families. In addition, you can configure aggregate CoS when IPv4
and IPv6 families share a logical interface, and per-family CoS when IPv4 and
IPv6 families do not share a logical interface (such as a demux interface).
The following new predefined variables have been added to implement IPv6
addressing for subscriber services:
Dynamic Profile Variable
Definition
$junos-framed-route-ipv6-address-prefix
Route prefix of an IPv6 access route.
$junos-framed-route-ipv6-nexthop
Next-hop address of an IPv6 access route.
$junos-input-ipv6-filter
Attaches a filter based on RADIUS VSA 26-106 (IPv6-Ingress-Policy-Name)
to the interface.
$junos-ipv6-ndra-prefix
IPv6 prefix value used when configuring the Router Advertisement
protocol.
$junos-output-ipv6-filter
Attaches a filter based on RADIUS VSA 26-107 (IPv6-Egress-Policy-Name)
to the interface.
$junos-preferred-source-ipv6-address
Selects the preferred IPv6 source address associated with the loopback
address used for the subscriber.
$junos-subscriber-ipv6-address
IPv6 address of the subscriber.
RADIUS supports activation, deactivation, and change of authorization (CoA) for
IPv6 services. The following new RADIUS attributes and VSAs have been added

Support for dynamic PPPoE interfaces (M120, M320, and MX Series
routers)—Enables you to configure dynamically created PPPoE logical interfaces
over statically created underlying interfaces. For subscriber access purposes, the
dynamic PPPoE logical interface represents a dynamic PPPoE subscriber interface.
The router automatically and transparently creates the dynamic interface in
response to an external event, such as the receipt of traffic on an underlying
interface. For example, the router creates a dynamic PPPoE logical interface
when it receives a PPPoE Active Discovery Request (PADR) control packet from
the client on an underlying interface to which a PPPoE dynamic profile is
assigned. The router uses the information configured in the dynamic profile to
determine the properties of the dynamic PPPoE logical interface.
The use of dynamically created PPPoE interfaces gives you the flexibility of
having the router create the dynamic PPPoE logical interface only when the
subscriber logs in on the associated underlying interface. By contrast, statically
created interfaces always allocate and consume system resources upon interface
creation, even when no traffic is flowing on the interface. Configuring and using
dynamically created interfaces helps you effectively and conveniently manage
subscriber access networks that provide services to large numbers of subscribers.
Configuration of dynamic PPPoE logical interfaces is supported on Intelligent
Queuing 2 (IQ2) PICs on M120 and M320 Series routers, and on Trio MPC/MIC
interfaces on MX Series routers.
To configure a dynamic PPPoE logical interface:
1.
Configure a dynamic profile to define the attributes of the dynamic PPPoE
logical interface. To do so, include the following statements at the [edit
dynamic-profiles profile-name] hierarchy level:
dynamic-profiles {
profile-name {
■
31
interfaces pp0 {
unit $junos-interface-unit {
keepalives interval seconds;
no-keepalives;
pppoe-options {
underlying-interface "$junos-underlying-interface";
server;
}
ppp-options {
chap;
pap;
}
family inet {
unnumbered-address interface-name;
address address;
service {
input {
service-set service-set-name <service-filter filter-name>;
}
output {
service-set service-set-name <service-filter filter-name>;
}
}
filter {
input filter-name;
output filter-name;
}
}
}
}
}
}
You can use most of these same statements to configure statically created
PPPoE interfaces, with the following important differences. When you
configure a profile to dynamically create a PPPoE interface, you must specify
the $junos-interface-unit predefined dynamic variable instead of the actual
logical unit number for the unit statement, and the $junos-underlying-interface
predefined dynamic variable instead of the actual name of the underlying
interface for the underlying-interface statement.
2.
Assign the dynamic profile to the underlying interface on which the router
creates the dynamic PPPoE interface. To do so, include the
pppoe-underlying-options statement at the [edit interfaces interface-name unit
logical-unit-number] hierarchy level, as follows:
interfaces {
interface-name {
unit logical-unit-number {
encapsulation ppp-over-ethernet;
pppoe-underlying-options {
access-concentrator name;
dynamic-profile profile-name;
duplicate-protection;
max-sessions number;
}
32
■
}
}
}
The statements at the [edit interfaces interface-name unit logical-unit-number
pppoe-underlying-options] hierarchy level define the following PPPoE-specific
attributes for the underlying interface:
■
To provide an alternative access concentrator (AC) name in the AC-NAME
tag in a PPPoE control packet, include the access-concentrator statement.
■
To assign a previously configured dynamic profile to the underlying
interface, include the dynamic-profile statement. This is the only required
statement for configuring dynamic PPPoE interfaces at the [edit interfaces
interface-name unit logical-unit-number pppoe-underlying-options] hierarchy
level.
■
To prevent the activation of another dynamic PPPoE logical interface
on the same underlying interface on which a dynamic PPPoE logical
interface is already active for the same client, include the
duplicate-protection statement.
■
To configure the maximum number of dynamic PPPoE logical interfaces
(sessions) that the router can activate on the underlying interface, include
the max-sessions statement.
To display information about the dynamic PPPoE interface configuration, use
the show pppoe underlying-interfaces, show pppoe statistics, and show pppoe
interfaces operational commands. You can also use the clear pppoe statistics
command to clear packet statistics on the underlying interface.

Support for PPPoE Layer 3 wholesale configuration in a subscriber access
network—Enables you to configure PPPoE Layer 3 wholesaling within a
subscriber access network. Wholesale access is the process by which an access
network provider partitions the access network into separately manageable and
accountable subscriber segments for resale to other network providers. An access
network provider may elect to wholesale all or part of its network to one or more
service providers (retailers).
In a Juniper Networks subscriber access network, you accomplish Layer 3
partitioning through the use of logical systems (LSs) and routing instances. Logical
systems enable you to divide a physical router into separate, distinct, logical
administrative domains. This method of division enables multiple providers to
administer the router simultaneously and each have access to only the portions
of the configuration that are relevant to their specific logical system. The JUNOS
Software supports up to 15 named logical systems in addition to the default
logical system (inet.0).
Routing instances are typically used in Layer 3 VPN scenarios. A routing instance
does not have the same level of administrative separation as does a logical
system. The routing instance defines a distinct routing table, set of routing
policies, and set of interfaces, but it does not provide administrative isolation.
■
33
When configuring PPPoE Layer 3 wholesale for a subscriber access network,
keep the following in mind:
■
PPPoE Layer 3 wholesaling supports the use of only the default logical system
using multiple routing instances.
■
Each routing instance must contain a loopback with one or more addresses
to be used for the unnumbered interface. However, unlike configuring Layer
3 wholesale for DHCP, the loopback interface address does not have to be
within the same subnetwork as the client IP address.
■
The system ignores the preferred-source-address option for the
unnumbered-address statement when it is configured. To avoid confusion,
we recommend that you do not configure the preferred-source-address option
for the unnumbered-address statement when configuring an unnumbered
interface. However, the system will function appropriately, regardless of
whether or not you have configured the preferred-source-address option.
To configure PPPoE Layer 3 wholesale for a subscriber access network:
■
Include the routing-instances statement along with the $junos-routing-instance
dynamic variable at the [edit dynamic-profiles profile-name] hierarchy level.
■
Include the interface statement along with the $junos-interface-name dynamic
variable at the [edit dynamic-profiles profile-name routing-instances
“$junos-routing-instance”] hierarchy level.
■
Include the unnumbered-address statement along with $junos-loopback-interface
dynamic variable at the [edit dynamic-profiles profile-name interfaces pp0 unit
“$junos-interface-unit” family inet] hierarchy level.
To view the logical system and routing instance for each subscriber, use the show
subscriber operational command.

PPP PAP and CHAP enhancements for subscriber management (M120 and
M320 routers)—Subscriber management supports both bidirectional and
unidirectional PPP PAP and CHAP authentication.
In subscriber management, the router's PPP interface typically authenticates the
remote client (the subscriber). Bidirectional authentication is not usually used in
a subscriber management environment, even though it is supported for static
interfaces. Also, subscriber management uses AAA to authenticate subscribers,
which removes the need to specify an access profile or a default password for
PAP or CHAP authentication.
34
■
■
For static interfaces, the router supports bidirectional authentication. If you
do not include the passive statement in the configuration, the router functions
as the authenticator for remote clients. If you include the passive statement,
the router is authenticated by the remote client. Also, when you specify the
passive statement for static interfaces, you must specify other attributes, as
described in the JUNOS Network Interfaces Guide.
■
For dynamic interfaces, the router supports unidirectional authentication
only—the router always functions as the authenticator. When you configure
PPP authentication in a dynamic profile (at the [edit dynamic-profiles] hierarchy
level), the pap and chap statements do not support any additional
configuration options, including the passive statement. PPP dynamic
interfaces are supported only on PPPoE interfaces (interface pp0) for this
release.
To configure CHAP or PAP authentication for static interfaces, use the following
stanza:
[edit interfaces interface-name unit logical-unit-number]
ppp-options {
chap {
access-profile name;
default-chap-secret name;
local-name name;
passive;
}
pap {
access-profile name
default-pap-password password;
local-name name;
local-password password;
passive;
}
}
To configure CHAP or PAP authentication for dynamic interfaces, use the following
stanza:
[edit dynamic-profiles profile-name interfaces pp0 unit $junos-interface-unit]
ppp-options {
chap;
pap;
}

To apply input and output filters for logical interfaces, include the input
input-filter-name and output output-filter-name statements. To apply these filters
statically, include the statements at the [edit interfaces interface-name unit
logical-unit-number filter] hierarchy level. To apply these filters dynamically, include
the statements at the [edit dynamic-profiles profile-name interfaces interface-name

Support for demux VLAN interface configuration on Ethernet and aggregate
Ethernet Trio MPC/MIC interfaces—Enables the static or dynamic creation of
demux VLAN interfaces with an underlying interface of aggregate Ethernet or
Gigabit/10–Gigabit Ethernet.
When configuring static VLAN demux interfaces, specify a VLAN ID for the vlan-id
statement at the [edit dynamic-profiles profile-name interfaces demux0 unit
unit-number] hierarchy level. You must also specify the underlying device name
for the underlying-interface statement at the [edit dynamic-profiles profile-name
interfaces demux0 unit unit-number demux-options] hierarchy level.
When configuring dynamic VLAN demux interfaces, specify the VLAN ID variable
($junos-vlan-id) for the vlan-id statement at the [edit dynamic-profiles profile-name
interfaces demux0 unit unit-number] hierarchy level. You must also specify the
underlying device name variable ($junos-interface-ifd-name) for the
underlying-interface statement at the [edit dynamic-profiles profile-name interfaces
demux0 unit unit-number demux-options] hierarchy level.
In addition, keep the following in mind while configuring dynamic VLANs over
IP demux interfaces:
■
Only single VLAN and stacked VLAN tag options are supported as VLAN
selectors.
■
IP demux over IP demux stacking is not supported.
■
This support is limited to Trio MPC/MIC interfaces on MX Series routers.

Enhanced support for up to 64 ECMP next hops for load balancing on M10i
routers with Enhanced CFEB, M320, M120, MX Series, and T Series Core
routers—The JUNOS Software supports configurations of 16, 32, or 64 equal-cost
multipath (ECMP) next hops for RSVP and LDP LSPs on M10i routers with an
Enhanced CFEB, and M320, M120, MX Series, and T Series routers. For networks
with high-volume traffic, this provides more flexibility to load-balance the traffic
over as many as 64 LSPs.
To configure the maximum limit for ECMP next hops, include the maximum-ecmp
next-hops statement at the [edit chassis] hierarchy level:
[edit chassis]
maximum-ecmp next-hops;
You can configure a maximum ECMP next-hop limit of 16, 32, or 64 using this
statement. The default limit is 16.
The following types of routes support the ECMP maximum next-hop configuration
for as many as 64 ECMP gateways:
38
■
■
Static IPv4 and IPv6 routes with direct and indirect next-hop ECMPs
■
LDP ingress and transit routes learned through associated IGP routes
■
RSVP ECMP next hops created for LSPs
■
OSPF IPv4 and IPv6 route ECMPs
■
ISIS IPv4 and IPv6 route ECMPs
■
EBGP IPv4 and IPv6 route ECMPs
■
IBGP (resolving over IGP routes) IPv4 and IPv6 route ECMPs
The enhanced ECMP limit of up to 64 ECMP next hops is also applicable for
Layer 3 VPNs, Layer 2 VPNs, Layer 2 circuits, and VPLS services that resolve
over an MPLS route, because the available ECMP paths in the MPLS route can
also be used by such traffic.
NOTE:
The following FPCs on M320, T640, and T1600 routers only support 16 ECMP next
hops:
■
(M320, T640, and T1600 routers only) Enhanced II FPC1
■
(M320, T640, and T1600 routers only) Enhanced II FPC2
■
(M320 and T640 routers only) Enhanced II FPC3
■
(T640 and T1600 routers only) FPC2
■
(T640 and T1600 routers only) FPC3
If a maximum ECMP next-hop limit of 32 or 64 is configured on an M320, T640, or
T1600 router with any of these FPCs installed, the Packet Forwarding Engines on
these FPCs use only the first 16 ECMP next hops. For Packet Forwarding Engines on
FPCs that support only 16 ECMP next hops, the JUNOS Software generates a system
log message if a maximum ECMP next-hop limit of 32 or 64 is configured. However,
for Packet Forwarding Engines on other FPCs installed on the router, a maximum
configured ECMP limit of 32 or 64 ECMP next hops is applicable.
To view the details of the ECMP next hops, issue the show route command. The
show route summary command also shows the current configuration for the
maximum ECMP limit. To view details of the ECMP LDP paths, issue the traceroute
mpls ldp command.

Dynamic configuration of the router advertisement protocol—In a network
deployment where router interfaces are configured statically, you might need
to configure the router advertisement protocol on only a small number of
interfaces on which it might run. However, in a subscriber access network, static
configuration of the router advertisement protocol becomes impractical because
the number of interfaces that potentially need the router advertisement protocol
increases substantially. In addition, deploying services in a dynamic environment
requires dynamic modifications to interfaces as they are created. To ensure that
dynamic interfaces are created with the ability to use the router advertisement
protocol, this release supports their configuration dynamically at the [edit
dynamic-profiles profile-name protocols] hierarchy level. The dynamic profile applies
router advertisement protocol configuration to dynamic interfaces as they are
created.
To minimally configure the router advertisement protocol, include the
router-advertisement statement at the [edit dynamic-profiles profile-name protocols]
hierarchy level, and the interface statement along with the $junos-interface-name
dynamic variable. All other statements are optional.
Optional router advertisement protocol statements include current-hop-limit,
default-lifetime, managed-configuration, max-advertisement-interval,
min-advertisement-interval, no-managed-configuration, no-other-stateful-configuration,
other-stateful-configuration, prefix, reachable-time, and retransmit-timer. All of these
statements appear at the [edit dynamic-profiles profile-name protocols
router-advertisement] hierarchy level.
NOTE: Statements used for router advertisement protocol configuration at the [edit
dynamic-profiles profile-name protocols] hierarchy level are identical in function to the
same statements used for static router advertisement protocol configuration, with
the exception of the interface and prefix statements which use dynamic variables.

Enhancement to show oam ethernet link-fault-management detail command—The
output of the show oam ethernet link-fault-management detail command now
includes the following two new fields: OAM total symbol error event information
and OAM total frame error event information. These fields display the total number
of errored symbols and errored frames, respectively, and are updated at every
Changes in Default Behavior and Syntax in JUNOS Release 10.1 for M Series, MX Series, and T Series Routers
interval regardless of whether the threshold for sending event TLVs has been
crossed. Previously, the show oam ethernet link-fault management detail command
displayed only the number of errored symbols reported in TLV events transmitted
since the OAM layer was reset and the number of errored frames detected since
the OAM layer was reset.

Enhancement to show oam ethernet connectivity-fault-management
commands—The output of the show oam ethernet connectivity-fault-management
mep-statistics, show oam ethernet connectivity-fault-management interfaces, and
show oam ethernet connectivity-fault-management mep-database commands
includes the following three new fields: Out of sync 1DMs received, which displays
the number of out of sync one-way delay measurement packets received; Valid
DMMs received, which displays the number of valid two-way delay measurement
request packets received, and Invalid DMMs received, which displays the number
of invalid two-way delay measurement request packets received.
■
Logical and physical Ethernet interface bandwidth—If you configure a
bandwidth on a logical Ethernet interface greater than the bandwidth configured
for the corresponding physical Ethernet interface, the commit fails. The bandwidth
of the logical interface should always be less than the bandwidth of the physical
interface. If you do not configure a bandwidth for the logical interface, it is
automatically set to the bandwidth configured for the physical interface.
■
Support for line-rate mode on 10-port 10-Gigabit Oversubscribed Ethernet
(OSE) PIC (T640, T1600, TX Matrix Plus routers)— Enables you to configure
the T640, T1600, and TX Matrix Plus routers to operate the 10-port 10-Gigabit
OSE PIC in line-rate mode, in which the OSE PIC disables oversubscription and
operates in line-rate mode. By default, the 10-port 10-Gigabit OSE PIC operates
in 2:1 oversubscription mode.

New CoS information field added to the show interfaces extensive command
output—The output of the show interfaces extensive command now displays the
class-of-service queue allocation information of the physical interfaces (intelligent
queueing PICs such as IQ2 and so on) under the new class-of-service information
category. In the previous releases, the class-of-service queue allocation

Restriction on compatibility-mode adtran and verilink—On 2-port and 4-port
channelized DS3 (T3) IQ interfaces, you cannot configure compatibility-mode
adtran, or verilink at the [edit interfaces interface-name t3-options] hierarchy level.
If configured, the default mode is applied on both the interfaces, that is, no
subrating.
■
Support for internal clocking mode on OSE PICs—The 10-port 10-Gigabit
Oversubscribed Ethernet (OSE) PIC supports only internal clocking mode on its
ports.
■
Commit-time warning messages at the [edit interfaces] hierarchy level are
now system logged—CLI commit-time warnings displayed for configuration at
the [edit interfaces] hierarchy level have been removed and are now logged as
system log messages. This change is applicable to JUNOS Release 10.1R1 and
later, 10.0R2, and 9.3R4. [CLI User Guide]
■
Invalid count of queues—The PD-5-10XGE-SFPP PICs in T Series routers do not
display ingress control queue statistics as output from the show interfaces queue
xe-fpc/pic/port forwarding-class command. However, you can use the following
commands to display the ingress control queue statistics:
■

Enhancement to the show chassis fabric fpcs command—In JUNOS Release
10.1 and later, the show chassis fabric fpcs command issued on a T640 or T1600
router displays destination errors in addition to link errors. The command output
displays a list of Packet Forwarding Engines that have destination errors, for
those SIBs that are in the Check state. This enhancement is also applicable to
JUNOS Release 9.6 and 10.0. The following sample shows the enhanced output

longer displays the schedulers field, because there is no static scheduler
partitioning of schedulers among different ports in IQ2E.
■
Enhancement to the show chassis sibs command—The show chassis sibs
command now displays destination errors for SIBS in the Check state. In JUNOS
Release 10.1 and later and JUNOS Release 9.6 and 10.0, the command displays
the number of destination errors for SIBS in the Check state:

MPLS Applications
■
MPLS statistics file now optional—The file statement configured at the [edit
protocols mpls statistics] hierarchy level is now optional. You still must configure
the MPLS statistics statement to collect LSP statistics for the MPLS MIBs. Rather
than accessing the LSP statistics in the MPLS statistics file, you can view the
statistics using SNMP instead. This change helps to reduce disk space usage on
the routing engine, especially on routers on which numerous LSPs have been
configured.
[MPLS]
■
46
■
NSR tracing flags for MPLS—You can now configure MPLS tracing flags for
nonstop active routing (NSR) synchronization events. This enables you to track
the progress of NSR synchronization between Routing Engines and record these
operations to a log file. To configure, include the flag nsr-synchronization or flag
nsr-synchronization-detail statement at the [edit protocols mpls traceoptions]
hierarchy level. The two statements are not mutually exclusive; you can track
the events at a high level and in detail.
[High Availability, MPLS, Routing Protocols]
Multiplay
■
Border gateway function (BGF) improved efficiency and scalability through
use of service interface pools—You can now use service interface pools to
improve the maintainability and scalability of your service set configurations.
When your service sets handle VPN traffic, you must specify a service interface
pool for the next next-hop-service for the service sets. The interfaces that are
members of the pool can serve as either inside or outside interfaces.
You should also specify service interface pools as the next-hop service for service
sets that do not currently handle VPN traffic. You gain the immediate benefit of
more efficient resource utilization and you can add VPNs to the service set in
the future without reconfiguring your service sets.

Enhancement to show interfaces command—The show interfaces command
includes a new field, INET6 Address flags, that displays a flag for any IPv6 address
that is in a state other than “permanent” or “ready-to-use.”
■
The ipsec-sa sa-name firewall filter action is no longer supported on the MX Series
routers. To configure one or more actions for a firewall filter, include the actions
statement at the [edit firewall family family-name filter filter-name term term-name
then] hierarchy level.
[Policy]
■
Enhanced match-conditions support for VPLS and bridge firewall filters (MX
Series routers and routers with Enhanced IQ2 [IQ2E] PICs only)—The protocol
families vpls and bridge now support the interface-set match condition for firewall
filters. To configure, include the interface-set interface-set-name statement at the
[edit firewall family bridge filter filter-name term term-name from] or the [edit firewall
family vpls filter filter-name term term-name from] hierarchy level. The protocol
family bridge is supported only on MX Series routers.
An interface set is a set of logical interfaces used to configure hierarchical class-ofservice schedulers. Previously only the following protocol families supported the
interface-set match condition: ipv4, ipv6, any, and mpls.

Routing Protocols
■
OSPF sham link—An OSPF sham link is now installed in the routing table as a
hidden route. Previously, an OSPF sham link was not installed in the routing
table. In addition, a BGP route is no longer exported to OSPF if a corresponding
OSPF sham link is available. To configure a sham link, include the sham-link local
ip-address statement at the [edit routing-instances routing-instance-name protocols
ospf] hierarchy level.
[Routing Protocols]
■
Removal of BGP warning message—If a BGP group is created without any
defined peers, the warning message no longer appears when the configuration
is committed.
[Routing Protocols]
■
Increase in limit to external paths accepted for BGP route target filtering—You
can now specify for BGP to accept up to 256 external paths for route target
filtering. Previously, the maximum number that you could configure was 16.
The default value remains one (1). To specify the maximum number of external
paths for BGP to accept for route target filtering, include the external-paths number
statement at the [edit protocols bgp family route-target] hierarchy level. This
statement is also supported for BGP groups and neighbors.
[Routing Protocols]
■
Support for having the algorithm that determines the single best path evaluate
AS numbers in AS paths for VPN routes—By default, the third step of the
algorithm that determines the active route evaluates the length of the AS path
but not the contents of the AS path. In some VPN scenarios with BGP multiple
path routes, it can also be useful to compare the AS numbers of the AS paths
and to have the algorithm select the route whose AS numbers match. Include
the as-path-compare statement at the [edit routing-instances routing-instance-name
routing-options multipath] hierarchy level.

Option to clear tunnel MTU—To clear the tunnel MTU, include the tunnel-mtu
statement at the [edit services ipsec-vpn rule rule-name term term-name then]

■
New configuration to avoid IDP traffic loss (M120, M320, and MX Series
routers)—When the Multiservices PIC or DPC configured for a service set is either
administratively taken offline or undergoes a failure, all the traffic entering the
configured interface with an IDP service set would be dropped without
notification. To avoid this traffic loss, include the bypass-traffic-on-pic-failure
statement at the [edit services service-set service-set-name service-set-options]
hierarchy level and (for TCP traffic only) the ignore-errors tcp statement at the
[edit interfaces interface-name services-options] hierarchy level. When you configure
these statements, the affected packets are forwarded in the event of a
Multiservices PIC or DPC failure or going offline, as though interface-style services
were not configured. This issue applies only to M120, M320, and MX Series
routers.
■
M120 router performance with IDP—For M120 routers, the performance number
is 4500 connections per second when IDP is enabled.
■
Enhancement to the output of the show services accounting commands—The
output for the show services accounting usage, show services accounting status,
show services accounting memory, and show services accounting errors operational
mode commands has been updated to include new fields for use in querying
service PICs.
■
Default idle timeout value for UDP- and TCP-based applications—Upon
identification by AppID, the default idle timeout value is set to 30 seconds for
UDP-based applications and 1 hour for TCP-based applications. These settings
can be overridden by including the idle timeout statement at the [edit services
application-identification application application] hierarchy level.
■
New statement to bypass traffic on exceeding flow limit—If the flow in the
service-set crosses the maximum limit set by the max-flow statement, the
bypass-traffic-on-exceeding-flow-limits allows the packets to bypass without
creating a new session. Following are the required privilege levels:
■
interface—To view the statement in the configuration
■
interface-control—To add the statement to the configuration
■
Diffie-Hellman group5 added to group1 and group2—The group5 designation
specifies that IKE should use the 1536-bit Diffie-Hellman prime modulus group
when performing the new Diffie-Hellman exchange. To configure the
Diffie-Hellman group for an IKE proposal, include the dh-group statement at the
[edit services ipsec-vpn ike proposal proposal-name] hierarchy level:
■
49
[edit services ipsec-vpn ike proposal proposal-name]
dh-group (group1 | group2| group5);
■
Permanent limitation for session-timeout on APPID—If session-timeout is
configured for an APPID application, a session for that application will be cleared
once the session-timeout expires. Once the same session is re-created as a new
session, it will not be identified by APPID.
■
Integrated Multi-Services Gateway (IMSG)—The clear services
border-signaling-gateway gateway-name statistics command no longer clears the
active calls counter.
■
New configuration statements for assigning policies—The following
configuration statements at the [edit services border-signaling-gateway gateway-name
service-point service-point-name service-policies] hierarchy level have been
deprecated and replaced by new statements:
■
new-call-usage-policies [policy-and-policy-set-names]
■
new-transaction-policies [policy-and-policy-set-names]
Each statement applied policies to calls or transactions entering at the service
point. Each is replaced by statements that explicitly apply policies to transactions
or policies entering the service point or exiting from the service point. The new
statements are:
■
new-call-usage-input-policies [policy-and-policy-set-names]
■
new-call-usage-output-policies [policy-and-policy-set-names]
■
new-transaction-input-policies [policy-and-policy-set-names]

[Services Interfaces, System Basics and Services Command Reference]
■
Requirement for client-to-servicer and server-to-client signatures—For certain
applications that have signatures for both client-to-server and server-to-client
directions, APPID (DAA) needs to see the data packets in both directions on the
same session to finish the identification process. For example, for SIP proxy
calls, the server may not send the response on the same session (different
destination port) and that session will not be identified as application junos:sip.

Enabling and disabling DHCP snooping support—You can now explicitly enable
or disable DHCP snooping support on the router. If you disable DHCP snooping
support, the router drops snooped DHCP discover and request messages.
To enable DHCP snooping support, include the allow-snooped-clients statement
at the [edit forwarding-options dhcp-relay overrides] hierarchy level. To disable
DHCP snooping support, include the no-allow-snooped-clients statement at the
[edit forwarding-options dhcp-relay overrides] hierarchy level. Both statements are
also supported at the named group level and per-interface level.
In JUNOS Release 10.0 and earlier, DHCP snooping is enabled by default. In
release 10.1 and later, DHCP snooping is disabled by default.
[Subscriber Access]
■
RADIUS interim accounting—When subscriber management receives the
RADIUS Acct-Interim-Interval attribute (attribute 85), RADIUS interim accounting
is performed based on the value in the attribute. The router uses the following
guidelines:
■
Attribute value is within the acceptable range (10 to 1440
minutes)—Accounting is updated at the specified interval.
■
Attribute value of 0—No RADIUS accounting is performed.
■
Attribute value is less than the minimum acceptable value (10
minutes)—Accounting is updated at the minimum interval.
■
Attribute value is greater than the maximum acceptable value (1440
minutes)—Accounting is updated at the maximum interval.
In previous releases, a RADIUS attribute set to zero (0) prevented subscribers
from connecting.

Restriction on the usage of the annotate command in the configuration
hierarchy—The JUNOS Software supports annotation of the configuration using
the annotate command up to the last level in the configuration hierarchy.
However, annotation of the configuration options or statements within the last
level in the hierarchy is not supported. For example, in the following sample
configuration hierarchy, annotation is supported up to the level 1 parent hierarchy,
but is not supported for the metric child statement:
[edit protocols]
isis {
interface ge-0/0/0.0 {
level 1 metric 10;
}
}
}
[CLI User Guide]
■
Support for accounting is restricted to events and operations on a master
Routing Engine—Starting with JUNOS Release 9.3, accounting for backup Routing
Engine events or operations is not supported on accounting servers such as
TACACS+ or RADIUS. Accounting is only supported for events or operations on
a master Routing Engine.

■
SCU support for VRF routing instances with vrf-table-label configured—You
can now configure source class usage (SCU) to count packets on Layer 3 VPNs
configured with the vrf-table-label statement. Include the source-class-usage
statement at the [edit routing-instances routing-instance-name vrf-table-label]
hierarchy level. The source-class-usage statement at this hierarchy level is
supported only for the virtual routing and forward (VRF) instance type. Previously,
you could not enable SCU when the vrf-table-label statement was configured.
Destination class usage (DCU) is not supported when the vrf-table-label is
configured.

■
Mirroring IRB packets as Layer 2 packets (MX Series router)—If you associate
an IRB with the bridge domain (or VPLS routing instance), and also configure
within the bridge domain (or VPLS routing instance) a forwarding table filter with
the port-mirror or port-mirror-instance action, then the IRB packet is mirrored as
a Layer 2 packet. You can disable this behavior by configuring the
no-irb-layer-2-copy statement in the bridge domain (or VPLS routing instance).
[MX Series Layer 2 Configuration]
■
Layer 2 circuits, call admission control (CAC), and bypass LSPs—You can now
configure CAC on Layer 2 circuit-based LSPs with bandwidth constraints and
also enable link and node protection. However, if the primary LSP fails, CAC
might not be applied to the bypass LSP, meaning that the bypass LSP might not
meet the bandwidth constraint for the Layer 2 circuit. To minimize the risk of
losing traffic, the Layer 2 circuit continues to use the non-CAC bypass LSP while
an attempt is made to establish a new Layer 2 circuit route over an LSP that does
support CAC. Previously, the Layer 2 circuit route was deleted if the bypass LSP
did not have sufficient bandwidth.
[VPNs]
■
Service VLANs and the use of vlan-id all statement in a VPLS routing
instance—If you configure the vlan-id all statement in a VPLS routing instance,
we recommend using the input-vlan-map pop and output-vlan-map push statements
on the logical interface to pop the service VLAN ID on input and push the service
VLAN ID on output and in this way limit the impact of doubly-tagged frames on
scaling.
[MX Series Layer 2 Configuration]
■
Layer 2.5 VPNs support ISO family and MPLS family over TCC (MX Series
routers)—JUNOS Release 8.3 introduced support for M320 and T Series routers.
JUNOS Release 10.1 extends support to MX Series routers.
Interfaces supporting TCC (Ethernet, extended VLANs, PPP, HDLC, ATM, and
Frame Relay) support ISO traffic and MPLS traffic on Layer 2.5 VPNs. Previously,
Layer 2.5 VPNs configured on MX Series routers supported only inet traffic. For
a protocol to be supported on a Layer 2.5 VPN, you must configure both ends
of the VPN with the protocol configuration. IPv6 is not supported.
To enable ISO or MPLS traffic over TCC, include the mpls or iso statement at the
[edit interfaces interface-name unit logical-unit-number family tcc protocol] hierarchy
level. To display which protocol is supported for an interface, issue the show
interfaces interface-name extensive operational mode command. The protocol is
displayed in the Flags field.
To enable ISO over TCC in cases in which the Ethernet interface is on a
customer-edge (CE) router, include the point-to-point statement at the [edit
protocols isis interface interface-name] hierarchy level on the CE router. When
you include this statement, the IS-IS protocol treats the Ethernet interface as
point to point, even though the actual interface is a LAN interface.
The M Series routing platforms continue to support only inet traffic for Layer 2.5
VPNs.

■
New configuration statement for removing dynamically learned MAC
addresses from the MAC address database—Media access control (MAC) flush
processing removes MAC addresses from the MAC address database that have
■
53
been learned dynamically. With the dynamically learned MAC addresses removed,
MAC address convergence requires less time to complete.
In this release, you enable MAC flush processing for the virtual private LAN
service (VPLS) routing instance or for the mesh group under a VPLS routing
instance by using the mac-flush statement instead of the mac-tlv-receive and
mac-tlv-send statements.
mac-flush [ explicit-mac-flush-message-options ];
To clear dynamically learned MAC addresses globally across all devices
participating in the routing instance, you can include the statement at the
following hierarchy levels:
■
[edit logical-systems logical-system-name routing-instances routing-instance-name
protocols vpls]
■
[edit routing-instances routing-instance-name protocols vpls]
To clear the MAC addresses on the routers in a specific mesh group, you can
include the statement at the following hierarchy levels:
■
[edit logical-systems logical-system-name routing-instances routing-instance-name
protocols vpls mesh-group mesh-group-name]
■
[edit routing-instances routing-instance-name protocols vpls
mesh-group mesh-group-name]
NOTE: The mac-tlv-receive and mac-tlv-send statements were removed from
Release 10.0 of the JUNOS Software and are no longer visible in the [edit
logical-systems logical-system-name routing-instances routing-instance-name protocols vpls]
and [edit routing-instances routing-instance-name protocols vpls] hierarchy levels.
Although the mac-tlv-receive and mac-tlv-send statements are recognized in the current
release, they will be removed in a future release. We recommend that you update
your configurations and use the mac-flush statement.
To also configure the router to send explicit MAC flush messages, you can include
explicit-mac-flush-message-options with the statement:
■
any-interface—(Optional) Send a MAC flush message when any
customer-facing attachment circuit interface goes down.
■
any-spoke—(Optional) Send a MAC FLUSH-FROM-ME flush message to all
provider edge (PE) routers in the core when one of the spoke pseudowires
between the multitenant unit switch and the other network-facing provider
edge (NPE) router goes down, causing the multitenant unit switch to switch
to the this NPE router.
54
■
Issues in JUNOS Release 10.1 for M Series, MX Series, and T Series Routers
NOTE: This option has a similar effect in a VPLS multihoming environment with
multiple multitenant unit switches connected to NPE routers, where both multitenant
unit switches have pseudowires that terminate in a mesh group with local-switching
configured. If the any-spoke option is enabled, then both PE routers send MAC
FLUSH-FROM-ME flush messages to all PEs in the core.
■
propagate—(Optional) Propagate MAC flush to the core.

Configuring passive clients to run on demultiplexer interfaces does not result in
the access-internal route pointing to the client demultiplexer interface as expected.
When configuring passive clients on demultiplexer interfaces, keep the following
in mind:
■
Configuring passive clients on demultiplexer interfaces requires specific
static route additions to function properly.
■
Only unnumbered demultiplexer is supported. However, the underlying
interface can be either numbered or unnumbered.
When configuring passive clients over demultiplexer interfaces by using
unnumbered underlying interfaces, you must add static routes for both the
client-facing and DHCP server-facing interfaces on the router as follows:
■
The configuration for the server-facing interface must contain the route IP
address of the DHCP relay agent and the qualified next-hop interface value
to the server.
■
The configuration for the client-facing interface must contain the link address
for the next-hop IP address of the server-facing interface and be configured
to resolve that IP address.
When configuring passive clients over demultiplexer interfaces by using numbered
underlying interfaces, you must add a static route such that the client-facing
interface configuration contains a next-hop address that points to the DHCP
server-facing interface on the router. [PR/511676]

On a TX Matrix router, an aggregate bundle composed of member links from
different LCCs has the same slot/PIC/port, and results in duplication of Link
Aggregation Control Protocol (LACP) port numbers. For example, a bundle with
actor and partner shown below will result in a duplicate LACP port number since
ge-0/3/0 and ge-8/3/0 (and similarly ge-1/3/0 and ge-9/3/0) are the same
slot/PIC/port but from different LCCs.
Actor
ge-0/3/0
ge-8/3/0
Partner
ge-1/3/0

On MX960 routers, duplicate LACP port numbers will result in aggregate bundles
composed of member links for the same PIC and port on slots (0, 8), (1,9), (2,10),
and (3,11). Also, the following sets of ports on any slot will have duplicate LACP
port numbers:
■
PIC 0 port 8 and PIC 1 port (0,8)
■
■
■
NOTE: The duplicate LACP port number described above does not affect the
aggregation, but affects the SNMP extracting port information and shows an identical

When the Border Signaling Gateway (BSG) configuration contains a policy that
has a term with regular expressions, configuration changes might not take effect
immediately after the commit process is complete. In most cases, the new policy
takes effect immediately. However, complex policies may take longer to take
effect depending on how many regular expressions they contain.
For example, if you have a term with four regular expressions, configuration
changes do not take effect until 50 seconds after you receive the message that
the commit process is complete. This behavior occurs whether you have a list
or regular expressions (for example, regular-expression [sip:88824.* sip:88821.*

committed with VPLS configured on the Gigabit Ethernet interface, and a
class-of-service classifier or rewrite rules that contain IEEE 802.1P on the interface
are used. [PR/408552: This issue has been resolved.]
■
On M Series and T Series routers, the forwarding class information is lost when
the packet enters the GRE tunnel with clear-dont-fragment-bit enabled. Additionally,
on an Enhanced FPC or M120 FEB, the packet is also likely to be dropped if it
is classified to a packet loss priority (PLP) value other than low. [PR/514162: This

■
After an 8216 Routing Engine upgrade to JUNOS Release 9.6 with "chassis"
deactivated, the backup Routing Engine starts to reboot with the panic message
"panic: filter_idx_alloc: invalid filter index" and crashes when the chassis
configuration is enabled and committed. After the Routing Engine finally comes
online, the CLI response is slow and the Routing Engine reboots again after three
minutes approximately. To stop these reboots, deactivate the chassis on the
backup Routing Engine. [PR/489029: This issue has been resolved.]

■
In JUNOS Release 9.3 and later, when routers using Enhanced FPCs
(T640-FPCx-ES or T1600-FPC4-ES FPCs) have a configuration involving CBF LSPs
and aggregate interfaces, a jtree corruption might occur when a flap from a
member link in the aggregate occurs on the remote end, or the FPC of the remote
router is rebooted. To avoid this issue, use indirect-next-hop (routing-options
forwarding-table indirect-next-hop). The error message “PFE: Detected error
nexthop:" indicates a jtree corruption. [PR/548436: This issue has been resolved.]

Class of Service
■
When you set the port speed of a multirate SONET Type 2 PIC to OC3, the
class-of-service (CoS) speed value is not changed correctly within the Packet
Forwarding Engine. The speed value remains OC12, which results in unexpected
CoS behavior. There is no workaround. [PR/279617: This issue has been resolved.]

■
On an Ichip-based platform for strict high priority queue (SHQ), the buffer size
allocated by the Packet Forwarding Engine is capped by the tx-rate. If the tx-rate
is configured to a very small value or is not configured, and is automatically
allotted a zero or a very small remaining value; the queue is also allotted a
proportionately small delay buffer. This can sometimes lead to Red and Tail
drops on the SHQ when there is a burst of traffic (with a certain traffic pattern)
on it. As a workaround, configure a nominal tx-rate value (5 percent) for the
SHQ. [PR/509513: This issue has been resolved.]
■
the packet enters the GRE tunnel with clear-dont-fragment-bit enabled.
Additionally, on an Enhanced FPC or M120 FEB, the packet is also likely to be

■
In a scaled configuration, the class-of-service classifier does not work properly.
■
Policers cannot be modified after a system upgrade due to a flaw in the parser
routine. This error occurs when the current item is deleted and the parser cannot
proceed to the next item. With the fix, the routine in the forwarding process
(dwfd) has been modified so that the next item in the object tree is fetched before
the current object is parsed. [PR/433418: This issue has been resolved.]

A targeted LDP neighbor may remain up with an old IP address that was
previously in use with the loopback address on the remote neighbor. This may
happen when either of the following is performed on the remote neighbor:
Network Management
MPLS Applications
82
■
■
A secondary loopback (lower than the current primary) address is added
and no primary keyword is associated with either of these addresses.
■
A second loopback address is added with the primary keyword.
This results in the targeted LDP neighbor being up with both IP addresses. The
neighbor with the old address may continue to remain up even after the old
loopback address is deleted on the remote neighbor. This neighborship with the
old address eventually times out when the router-id is changed to reflect the new
loopback address on the remote neighbor. [PR/518102: This issue has been
resolved.]
■
At adjust intervals, the maximum average bandwidth utilization for the LSP
should be reset to zero. MPLS sometimes fails to reset the maximum average
bandwidth utilization for the LSP to zero while performing a periodic
auto-bandwidth adjustment at the adjust interval. This prevents periodic
auto-bandwidth adjustment from adjusting to a lower bandwidth when the traffic
rate drops. [PR/528619: This issue has been resolved.]

On an I-chip-based platform for strict high priority queue (SHQ), the buffer size
allocated by the Packet Forwarding Engine is capped by the tx-rate. If the tx-rate
is configured to a very small value or is not configured, and is automatically
allotted a zero or a very small remaining value; the queue is also allotted a
proportionately small delay buffer. This can sometimes lead to red and tail drops
on the SHQ when there is a burst of traffic (with a certain traffic pattern) on it.
As a workaround, configure a nominal tx-rate value (5 percent) for the SHQ.

■
■
A secondary loopback (lower than the current primary) address is added
and no primary keyword is associated with either of these addresses.
■
A second loopback address is added with the primary keyword.
This results in the targeted LDP neighbor being up with both IP addresses. The
neighbor with the old address may continue to remain up even after the old
loopback address is deleted on the remote neighbor. This neighborship with the
old address eventually times out when the router-id is changed to reflect the new
loopback address on the remote neighbor. [PR/518102: This issue has been

■
At adjust intervals, the maximum average bandwidth utilization for the LSP
should be reset to zero. MPLS sometimes fails to reset the maximum average
bandwidth utilization for the LSP to zero while performing a periodic
auto-bandwidth adjustment at the adjust interval. This prevents periodic
auto-bandwidth adjustment from adjusting to a lower bandwidth when the traffic
rate drops. [PR/528619: This issue has been resolved.]
■
The maximum average bandwidth utilization computed by MPLS for
auto-bandwidth might sometimes be higher than the actual traffic rate (twice

The Configuring Layer 2 Circuit Transport Mode chapter in the Network Interfaces

For Layer 2 circuit cell relay and Layer 2 trunk modes, the atm-l2circuit-mode
cell statement at the [edit chassis fpc slot pic slot] hierarchy level and the
encapsulation atm-ccc-cell-relay statement at the [edit interface interface-name]
hierarchy level.
The configuration above is correct and will interoperate with routers running all
versions of JUNOS Software.
However, the chapter does not mention that you can also include the
encapsulation atm-ccc-cell-relay statement at the [edit interface interface-name unit
logical-unit-number] hierarchy level. When you use this configuration, keep the
following points in mind:

In the chapter Summary of JUNOS XML and XSLT Tag Elements Used in Commit
Scripts, the <change> and <transient-change> tag element summaries include
attributes for both tags. Neither the <change> tag nor the <transient-change> tag
have attributes. All references to the attributes in the Description section are not
applicable to these tags.
[Junos Configuration and Diagnostic Automation Guide]
The Subscriber Access Configuration Guide contains the following dynamic variable
errors:
■
The Configuring a Dynamic Profile for Client Access topic erroneously uses the
$junos-underlying-interface variable when a IGMP interface is configured in the
client access dynamic profile. The following example provides the appropriate
use of the $junos-interface-name variable:
[edit dynamic-profiles access-profile]
user@host# set protocols igmp interface $junos-interface-name
■
Table 25 in the Dynamic Variables Overview topic neglects to define the
$junos-igmp-version predefined dynamic variable. This variable is defined as
follows:
$junos-igmp-version—IGMP version configured in a client access profile. The
JUNOS Software obtains this information from the RADIUS server when a
subscriber accesses the router. The version is applied to the accessing subscriber
when the profile is instantiated. You specify this variable at the [dynamic-profiles
profile-name protocols igmp] hierarchy level for the interface statement.
In addition, the Subscriber Access Configuration Guide erroneously specifies the
use of a colon (:) when you configure the dynamic profile to define the IGMP
110
■
version for client interfaces. The following example provides the appropriate
syntax for setting the IGMP interface to obtain the IGMP version from RADIUS:
[edit dynamic-profiles access-profile protocols igmp interface $junos-interface-name]
user@host# set version $junos-igmp-version
■
The Subscriber Access Configuration Guide and the System Basics Configuration
Guide contain information about the override-nas-information statement. This
statement does not appear in the CLI and is not supported.
[Subscriber Access, System Basics]
■
When you modify dynamic CoS parameters with a RADIUS change of
authorization (CoA) message, the JUNOS Software accepts invalid configurations.
For example, if you specify that a transmit rate that exceeds the allowed 100
percent, the system does not reject the configuration and returns unexpected
shaping behavior.
[Subscriber Access]
■
We do not support multicast RIF mapping and ANCP when configured
simultaneously on the same logical interface. For example, we do not support
when a multicast VLAN and ANCP are configured on the same logical interface,
and the subscriber VLANs are the same for both ANCP and multicast.
[Subscriber Access]
■
The Guidelines for Configuring Dynamic CoS for Subscriber Access topic in the
Subscriber Access Configuration Guide erroneously states that dynamic CoS is
supported for dynamic VLANs on the Trio MPC/MIC family of products. In the
current release, dynamic CoS is supported only on static VLANs on Trio MPC/MIC
interfaces.
[Subscriber Access]
■
The Subscriber Access Configuration Guide incorrectly describes the
authentication-order statement as it is used for subscriber access management.
When configuring the authentication-order statement for subscriber access
management, you must always specify the radius method. Subscriber access
management does not support the password keyword (the default), and
authentication fails when you do not specify an authentication method.
[Subscriber Access]
■
In the JUNOS Subscriber Access Configuration Guide, Table 26, “RADIUS-Based
Mirroring Attributes” incorrectly indicates that RADIUS VSA 26-10,
Juniper-User-Permissions, is required for subscriber secure policy mirroring. In
fact, this VSA is not used.
[Subscriber Access]

■
The show system statistics bridge command displays system statistics on MX
Series routers. [System Basics Command Reference]
■
The mac-tlv-receive and mac-tlv-send statements were removed from Release 10.0
of the JUNOS Software and are no longer visible in the [edit logical-systems
logical-system-name routing-instances routing-instance-name protocols vpls] and
[edit routing-instances routing-instance-name protocols vpls] hierarchy levels.
Although the mac-tlv-receive and mac-tlv-send statements are recognized in the
current release, they will be removed in a future release. We recommend that
you update your configurations and use the mac-flush statement described in
the Changes in Default Behavior and Syntax in JUNOS Release 10.1 for M Series,
MX Series, and T Series Routers section of the release notes.
VPNs
[VPNs]
■
The JUNOS Software substantially supports the following RFCs for Layer 2 circuits,
as well as the Internet drafts listed in the published documentation:
■
RFC 4447, Pseudowire Setup and Maintenance Using the Label Distribution
Protocol (LDP)
The JUNOS Software does not support Section 5.3, “The Generalized PWid
FEC Element.”
■
RFC 4448, Encapsulation Methods for Transport of Ethernet over MPLS
Networks
[Hierarchy and Standards Reference]
■
In Chapter 19 Configuring VPLS of the VPNs Configuration Guide, an incorrect
statement that caused contradictory information about which platforms support
LDP BGP interworking has been removed. The M7i router was also omitted from
the list of supported platforms. The M7i router does support LDP BGP
interworking.

Basic Procedure for Upgrading to Release 10.1
In order to upgrade to JUNOS 10.0 or later, you must be running JUNOS 9.0S2, 9.1S1,
9.2R4, 9.3R3, 9.4R3, 9.5R1, or later minor versions, or you must specify the
no-validate option on the request system software install command.
When upgrading or downgrading the JUNOS Software, always use the jinstall package.
Use other packages (such as the jbundle package) only when so instructed by a Juniper
Networks support representative. For information about the contents of the jinstall
package and details of the installation process, see the Junos OS Installation and
Upgrade Guide.
NOTE: You cannot upgrade by more than three releases at a time. For example, if
your routing platform is running JUNOS Release 9.4 you can upgrade to JUNOS
Release 10.0 but not to JUNOS Release 10.1 As a workaround, first upgrade to JUNOS
Release 10.0 and then upgrade to JUNOS Release 10.1.
NOTE: With JUNOS Release 9.0 and later, the compact flash disk memory requirement
for JUNOS Software is 1 GB. For M7i and M10i routers with only 256 MB memory,
see the Customer Support Center JTAC Technical Bulletin PSN-2007-10-001 at
https://www.juniper.net/alerts/viewalert.jsp?txtAlertNumber=PSN-2007-10-001&actionBtn=Search.
■
113
NOTE: Before upgrading, back up the file system and the currently active JUNOS
configuration so that you can recover to a known, stable environment in case the
upgrade is unsuccessful. Issue the following command:
user@host> request system snapshot
The installation process rebuilds the file system and completely reinstalls the JUNOS
Software. Configuration information from the previous software installation is retained,
but the contents of log files might be erased. Stored files on the routing platform,
such as configuration templates and shell scripts (the only exceptions are the
juniper.conf and ssh files) may be removed. To preserve the stored files, copy them
to another system before upgrading or downgrading the routing platform. For more
information, see the Junos OS System Basics Configuration Guide.
114
■
The download and installation process for JUNOS Release 10.1 is the same as for
previous JUNOS releases.
If you are not familiar with the download and installation process, follow these steps:
1.
Using a Web browser, follow the links to the download URL on the Juniper
Networks Web page. Choose either Canada and U.S. Version or Worldwide
Version:
■
https://www.juniper.net/support/csc/swdist-domestic/ (customers in the United
States and Canada)
■
https://www.juniper.net/support/csc/swdist-ww/ (all other customers)
2.
Log in to the Juniper Networks authentication system using the username
(generally your e-mail address) and password supplied by Juniper Networks
representatives.
3.
Download the software to a local host.
4.
Copy the software to the routing platform or to your internal software distribution
site.
5.
Install the new jinstall package on the routing platform.
NOTE: We recommend that you upgrade all software packages out of band using
the console because in-band connections are lost during the upgrade process.
Customers in the United States and Canada use the following command:
user@host> request system software add validate reboot
source/jinstall-10.1SR4.4-domestic-signed.tgz
All other customers use the following command:
user@host> request system software add validate reboot
source/jinstall-10.1SR4.4-export-signed.tgz
Replace source with one of the following values:
■
/pathname—For a software package that is installed from a local directory
on the router.
■
For software packages that are downloaded and installed from a remote
location:
■
ftp://hostname/pathname
■
http://hostname/pathname
■
scp://hostname/pathname (available only for Canada and U.S. version)
The validate option validates the software package against the current
configuration as a prerequisite to adding the software package to ensure that
the router reboots successfully. This is the default behavior when the software
package being added is a different release.
■
115
Adding the reboot command reboots the router after the upgrade is validated
and installed. When the reboot is complete, the router displays the login prompt.
The loading process can take 5 to 10 minutes.
Rebooting occurs only if the upgrade is successful.
NOTE: After you install a JUNOS 10.1 Release jinstall package, you cannot issue the
request system software rollback command to return to the previously installed
software. Instead you must issue the request system software add validate command
and specify the jinstall package that corresponds to the previously installed software.
NOTE: Before you upgrade a router that you are using for voice traffic, you should
monitor call traffic on each virtual BGF. Confirm that no emergency calls are active.
When you have determined that no emergency calls are active, you can wait for
nonemergency call traffic to drain as a result of graceful shutdown, or you can force
a shutdown. For detailed information on how to monitor call traffic before upgrading,
see the JUNOS Multiplay Solutions Guide.
Upgrading a Router with Redundant Routing Engines
If the router has two Routing Engines, perform a JUNOS Software installation on each
Routing Engine separately to avoid disrupting network operation as follows:
1.
Disable graceful Routing Engine switchover (GRES) on the master Routing Engine
and save the configuration change to both Routing Engines.
2.
Install the new JUNOS Software release on the backup Routing Engine while
keeping the currently running software version on the master Routing Engine.
3.
After making sure that the new software version is running correctly on the
backup Routing Engine, switch over to the backup Routing Engine to activate
the new software.
4.
Install the new software on the original master Routing Engine that is now active
as the backup Routing Engine.
For the detailed procedure, see the Junos OS Installation and Upgrade Guide.
Upgrading Juniper Routers Running Draft-Rosen Multicast VPN to JUNOS
Release 10.1
In releases prior to JUNOS Release 10.1, the draft-rosen multicast VPN feature
implements the unicast lo0.x address configured within that instance as the source
address used to establish PIM neighbors and create the multicast tunnel. In this mode,
the multicast VPN loopback address is used for reverse path forwarding (RPF) route
resolution to create the reverse path tree (RPT), or multicast tunnel. The multicast
VPN loopback address is also used as the source address in outgoing PIM control
messages.
116
■
In JUNOS Release 10.1 and later, you can use the router’s main instance loopback
(lo0.0) address (rather than the multicast VPN loopback address) to establish the PIM
state for the multicast VPN. We strongly recommend that you perform the following
procedure when upgrading to JUNOS Release 10.1 if your draft-rosen multicast VPN
network includes both Juniper Network routers and other vendors’ routers functioning
as provider edge (PE) routers. Doing so preserves multicast VPN connectivity
throughout the upgrade process.
Because JUNOS Release 10.1 supports using the router’s main instance loopback
(lo0.0) address, it is no longer necessary for the multicast VPN loopback address to
match the main instance loopback adddress lo0.0 to maintain interoperability.
NOTE: You might want to maintain a multicast VPN instance lo0.x address to use
for protocol peering (such as IBGP sessions), or as a stable router identifier, or to
support the PIM bootstrap server function within the VPN instance.
Complete the following steps when upgrading routers in your draft-rosen multicast
VPN network to JUNOS Release 10.1 if you want to configure the routers’s main
instance loopback address for draft-rosen multicast VPN:
1.
Upgrade all PE routers to JUNOS Release 10.1 before you configure the loopback
address for draft-rosen Multicast VPN.
NOTE: Do not configure the new feature until all the PE routers in the network have
been upgraded to JUNOS Release 10.1.
2.
After you have upgraded all routers, configure each router’s main instance
loopback address as the source address for multicast interfaces. Include the
default-vpn-source interface-name loopback-interface-name] statement at the [edit
protocols pim] hierarchy level.
3.
After you have configured the router’s main loopback address on each PE router,
delete the multicast VPN loopback address (lo0.x) from all routers.
We also recommend that you remove the multicast VPN loopback address from
all PE routers from other vendors. In JUNOS releases prior to 10.1, to ensure
interoperability with other vendors’ routers in a draft-rosen multicast VPN
network, you had to perform additional configuration. Remove that configuration
from both the Juniper Networks routers and the other vendors’ routers. This
configuration should be on Juniper Networks routers and on the other vendors’
routers where you configured the lo0.mvpn address in each VRF instance as the
same address as the main loopback (lo0.0) address.
This configuration is not required when you upgrade to JUNOS Release 10.1 and
use the main loopback address as the source address for multicast interfaces.
NOTE: To maintain a loopback address for a specific instance, configure a loopback
address value that does not match the main instance address (lo0.0).
■
117
For more information about configuring the draft-rosen Multicast VPN feature, see
the JUNOS Multicast Configuration Guide.
Upgrading the Software for a Routing Matrix
A routing matrix can use either a TX Matrix router as the switch-card chassis (SCC)
or a TX Matrix Plus router as the switch-fabric chassis (SFC). By default, when you
upgrade software for a TX Matrix router or a TX Matrix Plus router, the new image
is loaded onto the TX Matrix or TX Matrix Plus router (specified in the JUNOS CLI by
using the scc or sfc option) and distributed to all T640 routers or T1600 routers in
the routing matrix (specified in the JUNOS CLI by using the lcc option). To avoid
network disruption during the upgrade, ensure the following conditions before
beginning the upgrade process:
■
A minimum of free disk space and DRAM on each Routing Engine. The software
upgrade will fail on any Routing Engine without the required amount of free disk
space and DRAM. To determine the amount of disk space currently available on
all Routing Engines of the routing matrix, use the CLI show system storage
command. To determine the amount of DRAM currently available on all the
Routing Engines in the routing matrix, use the CLI show chassis routing-engine
command.
■
The master Routing Engines of the TX Matrix or TX Matrix Plus router (SCC or
SFC) and T640 routers or T1600 routers (LCC) are all re0 or are all re1.
■
The backup Routing Engines of the TX Matrix or TX Matrix Plus router (SCC or
SFC) and T640 routers or T1600 routers (LCC) are all re1 or are all re0.
■
All master Routing Engines in all routers run the same version of software. This
is necessary for the routing matrix to operate.
■
All master and backup Routing Engines run the same version of software before
beginning the upgrade procedure. Different versions of the JUNOS Software can
have incompatible message formats especially if you turn on GRES. Because the
steps in the process include changing mastership, running the same version of
software is recommended.
■
For a routing matrix with a TX Matrix router, the same Routing Engine model is
used within a TX Matrix router (SCC) and within a T640 router (LCC) of a routing
matrix. For example, a routing matrix with an SCC using two RE-A-2000s and
an LCC using two RE-1600s is supported. However, an SCC or an LCC with two
different Routing Engine models is not supported. We suggest that all Routing
Engines be the same model throughout all routers in the routing matrix. To
determine the Routing Engine type, use the CLI show chassis hardware | match
routing command.
■
For a routing matrix with a TX Matrix Plus router, the SFC contains two model
RE-DUO-C2600-16G Routing Engines, and each LCC contains two model
RE-DUO-C1800-8G Routing Engines.
NOTE: It is considered best practice to make sure that all master Routing Engines
are re0 and all backup Routing Engines are re1 (or vice versa). For the purposes of
this document, the master Routing Engine is re0 and the backup Routing Engine is
re1.
118
■
To upgrade the software for a routing matrix, perform the following steps:
1.
Disable graceful Routing Engine switchover (GRES) on the master Routing Engine
(re0) and save the configuration change to both Routing Engines.
2.
Install the new JUNOS Software release on the backup Routing Engine (re1) while
keeping the currently running software version on the master Routing Engine
(re0).
3.
Load the new JUNOS Software on the backup Routing Engine. After making sure
that the new software version is running correctly on the backup Routing Engine
(re1), switch mastership back to the original master Routing Engine (re0) to
activate the new software.
4.
Install the new software on the new backup Routing Engine (re0).
For the detailed procedure, see the Routing Matrix with a TX Matrix Feature Guide or the
Routing Matrix with a TX Matrix Plus Feature Guide.
Upgrading Using ISSU
Unified in-service software upgrade (ISSU) enables you to upgrade between two
different JUNOS Software releases with no disruption on the control plane and with
minimal disruption of traffic. Unified in-service software upgrade is only supported
by dual Routing Engine platforms. In addition, graceful Routing Engine switchover
(GRES) and nonstop active routing (NSR) must be enabled. For additional information
about using unified in-service software upgrade, see the Junos OS High Availability
Configuration Guide.
Upgrading from JUNOS Release 9.2 or Earlier on a Router Enabled for Both
PIM and NSR
JUNOS Release 9.3 introduced NSR support for PIM for IPv4 traffic. However, the
following PIM features are not currently supported with NSR. The commit operation
fails if the configuration includes both NSR and one or more of these features:
■
Anycast RP
■
Draft-Rosen multicast VPNs (MVPNs)
■
Local RP
■
Next-generation MVPNs with PIM provider tunnels
■
PIM join load balancing
JUNOS 9.3 Release introduced a new configuration statement that disables NSR for
PIM only, so that you can activate incompatible PIM features and continue to use
NSR for the other protocols on the router: the nonstop-routing disable statement at
the [edit protocols pim] hierarchy level. (Note that this statement disables NSR for all
PIM features, not only incompatible features.)
If neither NSR nor PIM is enabled on the router to be upgraded or if one of the
unsupported PIM features is enabled but NSR is not enabled, no additional steps are
necessary and you can use the standard upgrade procedure described in other sections
of these instructions. If NSR is enabled and no NSR-incompatible PIM features are
■
119
enabled, use the standard reboot or ISSU procedures described in the other sections
of these instructions.
Because the nonstop-routing disable statement was not available in JUNOS Release
9.2 and earlier, if both NSR and an incompatible PIM feature are enabled on a router
to be upgraded from JUNOS Release 9.2 or earlier to a later release, you must disable
PIM before the upgrade and reenable it after the router is running the upgraded
JUNOS Software and you have entered the nonstop-routing disable statement. If your
router is running JUNOS Release 9.3 or later, you can upgrade to a later release
without disabling NSR or PIM–simply use the standard reboot or ISSU procedures
described in the other sections of these instructions.
To disable and reenable PIM:
1.
On the router running JUNOS Release 9.2 or earlier, enter configuration mode
and disable PIM:
[edit]
user@host# deactivate protocols pim
user@host# commit
2.
Upgrade to JUNOS Release 9.3 or later software using the instructions appropriate
for the router type. You can either use the standard procedure with reboot or
use ISSU.
3.
After the router reboots and is running the upgraded JUNOS Software, enter
configuration mode, disable PIM NSR with the nonstop-routing disable statement,
and then reenable PIM:
[edit]
user@host# set protocols pim nonstop-routing disable
user@host# activate protocols pim
user@host# commit
Downgrade from Release 10.1
To downgrade from Release 10.1 to another supported release, follow the procedure
for upgrading, but replace the 10.1 jinstall package with one that corresponds to the
appropriate release.
NOTE: You cannot downgrade more than three releases. For example, if your routing
platform is running JUNOS Release 9.3, you can downgrade the software to
Release 9.0 directly, but not to Release 8.5 or earlier; as a workaround, you can first
downgrade to Release 9.0 and then downgrade to Release 8.5.
For more information, see the Junos OS Installation and Upgrade Guide.

JUNOS Software Release Notes for Juniper Networks SRX Series Services Gateways and J Series Services Routers
New Features in JUNOS Release 10.1 for SRX Series Services Gateways and J Series Services Routers
Software Features
Application Layer Gateways (ALGs)
■
DNS ALG—This feature is supported on SRX3400, SRX3600, SRX5600, and
SRX5800 devices in addition to existing support on SRX100, SRX210, SRX240,
and SRX650 devices. JUNOS Software for SRX Series devices provides Domain
Name System (DNS) support. The DNS ALG monitors DNS query and reply packets
and closes the session if the DNS flag indicates that the packet is a reply message.
To configure the DNS ALG, use the edit security alg dns statement at the [edit
security alg] hierarchy level.
[Junos OS Security Configuration Guide]
■
DNS doctoring support—This feature is supported on all SRX Series and J Series
devices.
Domain Name System (DNS) ALG functionality has been extended to support
static NAT. You should configure static NAT for the DNS server first. Then if the
DNS ALG is enabled, public-to-private and private-to-public static address
translation can occur for A-records in DNS replies.
The DNS ALG also now includes a maximum-message-length command option
with a value range of 512 to 8192 bytes and a default value of 512 bytes. The
DNS ALG will now drop traffic if the DNS message length exceeds the configured
maximum, if the domain name is more than 255 bytes, or if the label length is
more than 63 bytes. The ALG will also decompress domain name compression
pointers and retrieve their related full domain names, and check for the existence
of compression pointer loops and drop the traffic if a loop exists.
Note that the DNS ALG can translate the first 32 A-records in a single DNS reply.
A-records after the first 32 will not be handled. Also note that the DNS ALG
supports only IPv4 addresses and does not support VPN tunnels.
■
MS RPC ALG—This feature is now supported on SRX3400, SRX3600, SRX5600,
and SRX5800 devices in addition to existing support on SRX100, SRX210,
SRX240, SRX650, and J Series devices.
The Microsoft remote procedure call (RPC) provides a way for a program running
on one host to call procedures in a program running on another host. Because
of the large number of RPC services and the need to broadcast, the transport
address of an RPC service is dynamically negotiated based on the service
program’s Universal unique iDentifier (UUID). The specific UUID is mapped to
a transport address.
JUNOS Software supports MS RPC as a predefined service to allow and deny
traffic based on a policy you configure. The MS RPC ALG provides the functionality
for all supported devices to handle the dynamic transport address negotiation
mechanism of the MS RPC and to ensure UUID-based security policy enforcement.
You can define a security policy to permit or deny all RPC requests or to permit
or deny by specific UUID number. The ALG also supports route and Network
Address Translation (NAT) mode for incoming and outgoing requests.
■
123
■
SQL ALG—This feature is now supported on SRX3400, SRX3600, and SRX5600,
and SRX5800 devices in addition to existing support on SRX100, SRX210,
Enabling the Structured Query Language (SQL) ALG on an SRX Series device or
a J Series device allows SQL*Net traffic in SQL redirect mode to traverse an SRX
Series device by creating a TCP pinhole. If the the SQL*Net traffic is not in redirect
mode, it will not be handled by the SQL ALG and will instead be processed by
configured firewall policies. SQL*Net is a proprietary protocol used by Oracle
databases for data access and sharing over networks. Note that the SQL ALG
supports only IPv4 addresses as of JUNOS Release 10.1.
■
Sun RPC ALG—This feature is now supported on SRX3400, SRX3600, SRX5600,
and SRX5800 line devices in addition to existing support on SRX100, SRX210,
Sun Microsystems RPC provides a way for a program running on one host to
call procedures in a program running on another host. Because of the large
number of RPC services and the need to broadcast, the transport address of an
RPC service is dynamically negotiated based on the service’s program number
and version number. Several binding protocols are defined for mapping the RPC
program number and version number to a transport address.
JUNOS Software supports the Sun RPC as a predefined service to allow and deny
traffic, based on a security policy you configure. The Sun RPC ALG provides the
functionality for all supported devices to handle the dynamic transport address
negotiation mechanism of the Sun RPC and to ensure program number-based
security policy enforcement. You can define a security policy to permit or deny
all RPC requests or to permit or deny by specific program number. The ALG also
supports route and NAT mode for incoming and outgoing requests.
Chassis Cluster
■
Interface link aggregation in redundant Ethernet interfaces—This feature is
supported on SRX3400, SRX3600, SRX5600, and SRX5800 device chassis clusters.
Link aggregation groups (LAGs) can now be established across nodes in a chassis
cluster. In JUNOS Release 10.1, support for LAGs based on IEEE 802.3ad made
it possible to aggregate physical interface links on a standalone device. LAGs
provide increased interface bandwidth and link availability by linking physical
ports and load-balancing traffic crossing the combined interface. In JUNOS Release
10.1, link aggregation has been extended to chassis cluster configuration, allowing
a redundant Ethernet interface (known as a reth interface in CLI commands) to
add multiple child interfaces from both nodes and thereby create a redundant
Ethernet interface link aggregation group.
Other than adding more child interfaces (up to a maximum of 16, with 8 per
node) to a redundant Ethernet interface, no other configuration on an SRX Series
device beyond the more general chassis cluster, redundancy group, and redundant
Ethernet interface configuration is necessary to use this feature. It is necessary,
however, for the switch used to connect the links from both nodes in the cluster
124
■
to have a LAG link configured and 802.3ad enabled for each redundant Ethernet
interface LAG on both nodes so that the aggregate links will be recognized.
Standalone link aggregation group interfaces (ae) are supported on clustered
devices but cannot be added to redundant Ethernet interfaces. Likewise, any
child interface of an existing LAG cannot be added to a redundant Ethernet
interface, and vice versa. The maximum number of total combined standalone
aggregate interfaces (ae) and redundant Ethernet interfaces (reth) per cluster is
128.
Redundant Ethernet interface configuration also includes a minimum-links setting
that allows you to set a minimum number of physical child links in a redundant
Ethernet interface LAG that must be working on the primary node for the interface
to be up. The default minimum-links value is 1. When the number of physical
links on the primary node in a redundant Ethernet interface falls below the
minimum-links value, the interface will be down even if some links are still
working.
Note that management, control, and fabric interfaces do not support standalone
LAGs or redundant Ethernet interface LAGs in JUNOS Release 10.1.
■
Redundancy group IP address monitoring through a secondary interface—This
feature is supported on SRX3400, SRX3600, SRX5600 and SRX5800 devices.
In JUNOS Release 10.1, redundancy group IP address monitoring through a
redundant Ethernet (reth) interface has been extended to include monitoring of
addresses on secondary links as well as on primary links. Redundancy group
failover can thus be tied to the health of both any IP addresses that are currently
important to traffic reliability and to any IP addresses that will become important
to traffic reliability in the event of a failover.
Monitoring can be accomplished only if the IP address is reachable on a redundant
Ethernet interface, and IP addresses cannot be monitored over a tunnel. IP
address monitoring is not supported on redundant Ethernet interface LAGs or
on the child interfaces bound to a redundant Ethernet interface LAG. The feature
also cannot be used on a cluster running in transparent mode. The maximum
number of total monitoring IPs that can be configured per cluster remains 32
for SRX3400 and SRX3600 devices, and 64 for SRX5600 and SRX5800 devices.

Integrated Convergence Services
■
DSCP marking for RTP packets generated by SRX Series Integrated
Convergence Services—This feature is supported on SRX210 and SRX240 devices
that have high memory, power over Ethernet capability, and media gateway
capability.
Configure Differentiated Services (DiffServ) code point (DSCP) marking to set
the desired DSCP bits for Real-Time Transport Protocol (RTP) packets generated
by SRX Series Integrated Convergence Services.
DSCP bits are the 6-bit bit map in the IP header used by devices to determine
the forwarding priority of packet routing. When the DSCP bits of RTP packets
generated by Integrated Convergence Services are configured, the downstream
device can then classify the RTP packets and direct them to a higher priority
queue in order to achieve better voice quality when packet traffic is congested.
Juniper Networks devices provide classification, priority queuing, and other kinds
of class-of-service (CoS) configuration under the Class-of-Service configuration
hierarchy.
Note that the Integrated Convergence Services DSCP marking feature marks only
RTP packets of calls that it terminates, which include calls to peer call servers
and to peer proxy servers that provide SIP trunks. If a call is not terminated by
Integrated Convergence Services, then DSCP marking does not apply.
To configure the DSCP marking bitmap for calls terminated by Integrated
Convergence Services and the address of the peer call server or peer proxy server
to which these calls are routed, use the media-policy statement in the [edit services
converged-services] hierarchy level.
set services convergence-service service-class < name > dscp < bitmap >
set services convergence-service service-class media-policy < name > term
< term-name > from peer-address [< addresses >]
set services convergence-service service-class media-policy < name > term then

DOCSIS Mini-PIM interface—DOCSIS Mini-PIM is currently supported with
Comcast ISP service.
The Data over Cable Service Interface Specification (DOCSIS) defines the
communications and operation support interface requirements for a
data-over-cable system. It is used by cable operators to provide Internet access
over their existing cable infrastructure for both residential and business
customers. DOCSIS 3.0 is the latest interface standard, allowing channel bonding
to deliver speeds higher than 100 Mbps throughput in either direction, far
surpassing other WAN technologies such as T1/E1, ADSL2+, ISDN, and DS3.
DOCSIS network architecture includes a cable modem on SRX Series Services
Gateways with a DOCSIS Mini-Physical Interface Module (Mini-PIM) located at
customer premises, and a cable modem termination system (CMTS) located at
the head-end or data center locations. The standards-based DOCSIS 3.0 Mini-PIM
is interoperable with CMTS equipment. The DOCSIS Mini-PIM provides backward
compatibility with CMTS equipment based on the following standards:
126
■
■
DOCSIS 2.0
■
DOCSIS 1.1
■

The DOCSIS Mini-PIM is supported on the following SRX Series Services Gateways:
■
SRX210
■
SRX240
The DOCSIS Mini-PIM has the following key features:
■
Provides high data transfer rates of over 150 Mbps downstream
■
Supports 4-downstream and 4-upstream channel bonding
■
Supports quality of service (QoS)
■
Provides interoperability with any DOCSIS-compliant cable modem
termination system CMTS
■
Supports IPv6 and IPv4 for modem management interfaces
■
Supports Baseline Privacy Interface Plus (BPI+)
■
Supports Advanced Encryption Standard (AES)
■
Very-high-bit-rate digital subscriber line (VDSL)—VDSL technology is part of
the xDSL family of modem technologies that provide faster data transmission
over a single flat untwisted or twisted pair of copper wires.
The VDSL lines connect service provider networks and customer sites to provide
high bandwidth applications (Triple Play services) such as high-speed Internet
access, telephone services like voice over IP (VoIP), high-definition TV (HDTV),
and interactive gaming services over a single connection. VDSL2 is an
enhancement to VDSL and permits the transmission of asymmetric and
symmetric (full-duplex) aggregate data rates up to 100 Mbps on short copper
loops using a bandwidth of up to 30 MHz. The VDSL2 technology is based on
the ITU-T G.993.2 standard.
The following SRX Series Services Gateways support the VDSL2 Mini-Physical
Interface Module (Mini-PIM) (Annex A):
■
SRX210 Services Gateway
■
SRX240 Services Gateway
The VDSL2 Mini-PIM carries the Ethernet backplane. When the Mini-PIM is
plugged into the chassis, the Mini-PIM connects to one of the ports of the
baseboard switch.
■
127
The VDSL2 Mini-PIM supports the following features:
■
■
■
Asymmetric Digital Subscriber Line (ADSL), ADSL2, and ADSL2+ backward
compatibility with Annex-A, Annex-M Support
■
PTM or EFM [802.3ah] support
■
Operation, Administration, and Maintenance (OAM) support for
ADSL/ADSL/ADSL2+ Asynchronous Transfer Mode (ATM)
■
ATM quality of service (QoS) (supported only when the VDSL2 Mini-PIM is
operating in ADSL2 mode)
■
Multilink Point-to-Point Protocol (MLPPP) (supported only when the VDSL2
Mini-PIM is operating in ADSL2 mode)
■
Maximum Transmission Unit (MTU) size of 1500 bytes
■
Support for maximum of 10 permanent virtual circuits (PVCs) (only in
ADSL/ADSL2/ADSL2+ mode)
■
Dying gasp support (ADSL and VDSL2 mode)
Online insertion and removal (hot swap) for SRX650 GPIMs—Online insertion
and removal (OIR) functionality is supported on CPU-based and CPU-less
Gigabit-Backplane Physical Interface Modules (GPIMs). You can remove or insert
a GPIM without powering off the device. The following GPIMs are supported on
SRX650 devices:
■
24-port Ethernet GPIM (with and without Power over Ethernet [PoE])
■
16-port Ethernet GPIM (with and without PoE)
■
2-port and 4-port CT1/E1 GPIM
Implement the Point-to-Point Protocol over Ethernet (PPPoE)-based
radio-to-router protocol—This feature is supported on SRX Series and J Series
devices.
JUNOS Release 10.1 supports PPPoE-based radio-to-router protocols. These
protocols include messages that define how an external device provides the
router with timely information about the quality of a link’s connection. There is
also a flow control mechanism to indicate how much data the device can forward.
The device can then use the information provided in the PPPoE messages to
dynamically adjust the interface speed of the PPP links. Use the radio-router
statement from the [set interfaces <unit>] hierarchy to indicate that metrics
announcements received on the interface will be processed by the device.
■
Class of service (CoS) for devices operating in transparent mode—This feature
is supported on SRX3400, SRX3600, SRX5600, and SRX5800 devices.
SRX3400, SRX3600, SRX5600, and SRX5800 devices operating in Layer 2
transparent mode support the following CoS functions:
128
■
■
IEEE 802.1p behavior aggregate (BA) classifiers to determine the forwarding
treatment for packets entering the device
Note that only IEEE 802.1p BA classifier types are supported on devices
operating in transparent mode.
■
Rewrite rules to redefine IEEE 802.1 CoS values in outgoing packets
Note that rewrite rules that redefine IP precedence CoS values and DSCP
CoS values are not supported on devices operating in transparent mode.
■
Shapers to apply rate limiting to an interface
■
Schedulers that define the properties of an output queue
You configure BA classifiers and rewrite rules on transparent mode devices in
the same way as on devices operating in Layer 3 mode. For transparent mode
devices, however, you apply BA classifiers and rewrite rules only to logical
interfaces configured with the family bridge configuration statement.
You configure shapers and schedulers on transparent mode devices in the same
way as on devices operating in Layer 3 mode.
[Junos OS Interfaces and Routing Configuration Guide]
■
Layer 2 Q-in-Q tunneling—This feature is supported on SRX210, SRX240,
SRX650, and J Series devices.
Q-in-Q tunneling, defined by the IEEE 802.1ad standard, allows service providers
on Ethernet access networks to extend a Layer 2 Ethernet connection between
two customer sites.
In Q-in-Q tunneling, as a packet travels from a customer virtual LAN (C-VLAN)
to a service provider's VLAN, a service provider-specific 802.1Q tag is added to
the packet. This additional tag is used to segregate traffic into
service-provider-defined service VLANs (S-VLANs). The original customer 802.1Q
tag of the packet remains and is transmitted transparently, passing through the
service provider's network. As the packet leaves the S-VLAN in the downstream
direction, the extra 802.1Q tag is removed.
There are three ways to map C-VLANs to an S-VLAN:
■
All-in-one bundling—Use the dot1q-tunneling statement at the [edit vlans]
hierarchy to map without specifying customer VLANs. All packets from a
specific access interface are mapped to the S-VLAN.
■
Many-to-one bundling—Use the customer-vlans statement at the [edit vlans]
hierarchy to specify which C-VLANs are mapped to the S-VLAN.
■
Mapping C-VLAN on a specific interface—Use the mapping statement at the
[edit vlans] hierarchy to map a specific C-VLAN on a specified access interface
to the S-VLAN.
Table 3 on page 130 lists the C-VLAN-to-S-VLAN mapping supported on identified
SRX Series and J Series devices.

Integrated bridging and routing (IRB) interfaces are supported on Q-in-Q VLANs
for SRX210, SRX240, SRX650, and J Series devices. Packets arriving on an IRB
interface on a Q-in-Q virtual LAN (VLAN) are routed regardless of whether the
packet is single or double tagged. The outgoing routed packets contain an S-VLAN
tag only when exiting a trunk interface; the packets exit the interface untagged
when exiting an access interface.
In a Q-in-Q deployment, customer packets from downstream interfaces are
transported without any changes to the source and destination media access
control (MAC) addresses. You can disable MAC address learning at both the
interface level and the VLAN level. Disabling MAC address learning on an interface
disables learning for all the VLANs of which that interface is a member. When
you disable MAC address learning on a VLAN, MAC addresses that have already
been learned are flushed.
■
Layer 2 Link Layer Discovery Protocol (LLDP) and Link Layer Discovery
Protocol–Media Endpoint Discovery (LLDP-MED)—This feature is supported
on SRX100, SRX210, SRX240, SRX650, and J Series devices.
Devices use LLDP and LLDP-MED to learn and distribute device information on
network links. The information allows the device to quickly identify a variety of
systems, resulting in a LAN that interoperates smoothly and efficiently.
LLDP-capable devices transmit information in type length and value (TLV)
messages to neighbor devices. Device information can include specifics such as
chassis and port identification and system name and system capabilities. The
TLVs leverage this information from parameters that have already been configured
in the Juniper Networks JUNOS Software.
LLDP-MED goes one step further, exchanging IP-telephony messages between
the device and the IP telephone. These TLV messages provide detailed information
on PoE policy. The PoE management TLVs let the device ports advertise the
power level and power priority needed. For example, the device can compare
the power needed by an IP telephone running on a PoE interface with available
resources. If the device cannot meet the resources required by the IP telephone,
the device could negotiate with the telephone until a compromise on power is
reached.
LLDP and LLDP-MED must be explicitly configured on universal Physical Interface
Modules (uPIMs) (in enhanced switching mode) on J Series devices, base ports
on SRX100, SRX210, and SRX240 devices, and Gigabit-Backplane Physical
Interface Modules (GPIMs) on SRX650 devices. To configure LLDP on all interfaces
or on a specific interface, use the lldp statement at the [set protocols] hierarchy.
130
■
To configure LLDP-MED on all interfaces or on a specific interface, use the lldp-med
statement at the [set protocols] hierarchy.
■
Promiscuous mode—This feature is supported on SRX3400, SRX3600, SRX5600,
and SRX5800 devices.
When promiscuous mode is enabled on a Layer 3 Ethernet interface, all packets
received on the interface are sent to the CP/Services Processing Unit (SPU)
regardless of the destination MAC address of the packet. You can also enable
promiscuous mode on chassis cluster redundant Ethernet interfaces and
aggregated Ethernet interfaces. If you enable promiscuous mode on a redundant
Ethernet interface, promiscuous mode is then enabled on any child physical
interfaces. If you enable promiscuous mode on an aggregated Ethernet interface,
promiscuous mode is then enabled on all member interfaces.
To enable promiscuous mode on an interface, use the promiscuous-mode
statement at the [edit interfaces] hierarchy.
Intrusion Detection and Prevention (IDP)
■
IDP in an active/active chassis cluster—This feature is supported on SRX3400,
SRX3600, SRX5600, and SRX5800 devices.
Intrusion Detection and Prevention (IDP) can now monitor traffic on active/active
chassis clusters. As in active/passive clusters, sessions already in progress that
fail over or fail back are not inspected by IDP in an active/active cluster. New
sessions created after a failover will, however, be inspected by IDP. There are
no changes to IDP deployment or logging as a result of extending support to
active/active high-end device clusters.
IDP also now supports chassis cluster in-service software upgrades (ISSUs), which
means that new sessions will continue to be inspected during the ISSU. However,
because ISSU requires the nodes to fail over and fail back as the upgrade
proceeds, IDP monitoring of any sessions that fail over will cease. It should not
be necessary to restart IDP once the ISSU is completed. Note that IDP ISSU
support is available on both active/passive and active/active chassis clusters.
■
IDP application identification enhancement for extended applications with
threat prevention support—This feature is supported on SRX3400, SRX3600,
SRX5600, and SRX5800 devices.
With the increased use of application protocol encapsulation, the need arises to
support the identification of multiple different applications running on the same
Layer 7 protocols. In order to do this, the current application identification layer
is split into two layers: application and protocol. New extended application
signatures have been added to identify these extended applications.
■
Command-line interface (CLI) enhancements supported for J-Web—This
feature is supported on SRX Series and J Series devices.
■
131
Additional functionality has been added to existing IDP J-Web pages for several
new CLI commands that perform tasks such as the following: list detailed security
download status information, list subscriber policies, and add additional IDP
packet counters to differentiate a packet drop that is the result of a policy from
a legitimate drop or an error drop. There are several more newly added
commands.
[JUNOS CLI Reference Guide]
■
SNMP MIB for IDP Monitoring—This feature is now supported on SRX3400,
SRX3600, SRX5600, and SRX5800 devices in addition to existing support on
SRX100, SRX210, SRX240, and SRX650 devices.
■
Application-level DDoS logging—This feature is supported on SRX3400,
SRX3600, SRX5600, and SRX5800 devices with IDP enabled.
IDP now provides logging for application-level DDoS events. IDP generates three
types of application-level DDoS event logs: attack, state transition, and ip-action.
These event logs provide visibility into the application-level DDoS state and
provide notifications on occurrences of application-level DDoS attacks for each
protected application server.

Network Address Translation (NAT)
■
Increased maximum number of source NAT rules supported—This feature is
supported on SRX Series and J Series devices.
JUNOS Release 10.1 increases the number of source NAT rules and rule sets that
you can configure on a device. In previous releases, the maximum number of
source NAT rule sets you could configure on a device was 32 and the maximum
number of rules in a source NAT rule set was 8.
JUNOS Release 10.1, the maximum number of source NAT rules that you can
configure on a device are:
■
512 for J Series, SRX100, and SRX210 devices
■
1024 for SRX240 and SRX650 devices
■
8192 for SRX3400, SRX3600, SRX5600, and SRX5800 devices
These are systemwide maximums for total numbers of source NAT rules. There
is no limitation on the number of rules that you can configure in a source NAT
■
135
rule set as long as the maximum number of source NAT rules allowed on the
device is not exceeded.
NOTE: This features does not change the maximum number of rules and rule sets
you can configure on a device for static and destination NAT. For static NAT, you
can configure up to 32 rule sets and up to 256 rules per rule set. For destination NAT,
you can configure up to 32 rule sets and up to 8 rules per rule set.
Point-to-Point Protocol over Ethernet (PPPoE)
■
LN1000 mobile secure router—This feature is supported on J2320, J6350, and
SRX650 devices.
To support the credit-based flow control extensions described in [RFC–4938],
PPPoE peers can now grant each other forwarding credits. The grantee can
forward traffic to the peer only when it has a sufficient number of credits to do
so. When credit-based forwarding is used on both sides of the session, the radio
client can control the flow of traffic by limiting the number of credits it grants
to the router.
The interfaces statement includes a new radio-router attribute that replaces the
resource-component-variables attribute. The radio-router attribute contains the
parameters used for rate-based scheduling and OSPF link cost calculations. It
also includes a new credit attribute to indicate that credit-based packet scheduling
is supported on the PPPoE interfaces that reference this underlying interface.
Interfaces that set the encapsulation attribute support the PPPoE Active Discovery
Grant (PADG) and PPPoE Active Discovery Credit (PADC) messages in the same
way that the attribute provides active support for the PPPoE Active Discovery
Quality (PADQ) message.
The credit interval parameter controls how frequently the router generates credit
announcement messages. For PPPoE this corresponds to the interval between
PADG credit announcements for each session.
For example:
[edit interfaces ge-0/0/1]
unit 0 {
encapsulation ppp-over-ether;
radio-router {
credit {
interval 10;
}
bandwidth 80;
threshold 5;
}
}
NOTE: The resource-component-variables attribute has been deprecated, but has an
alias to the radio-router variable to minimize impact on existing routers that might
have been configured previously.

Virtual LANs (VLANs)
■
Flexible Ethernet services—This feature is supported on SRX210, SRX240,
SRX650, and J Series devices.
Use flexible Ethernet services encapsulation when you want to configure multiple
per-unit Ethernet encapsulations. This encapsulation type allows you to configure
any combination of route, TCC, CCC, and VPLS encapsulations on a single physical
port. Aggregated Ethernet bundles cannot use this encapsulation type.
For ports configured with flexible Ethernet services encapsulation, VLAN IDs
from 1 through 511 are no longer reserved for normal VLANs.
VPNs
■
Increased maximum number of VPN tunnels supported—This feature is
supported on SRX3400, SRX3600, SRX5600, and SRX5800 devices.
VPN supports a maximum of 10000 site-to-site VPN tunnels.
WLAN
■
AX411 Access Point clustering—The AX411 Access Point is a Layer 2 device
that connects wireless communication devices together to create a wireless
network. The access point is connected to the wired network and relays data
between the wired and the wireless network. Multiple access points form a part
of a bigger wireless network and can be clustered together.

The access point cluster is a dynamic, configuration-aware group of access points
in the same subnet of a network. A cluster can have up to sixteen member access
points. Clusters can share various configuration information such as virtual access
point (VAP) settings and quality-of-service (QoS) queue parameters. Any change
in configuration on one access point will propagate to all other access points in
the cluster. Similarly, any new access point introduced to the cluster will adopt
the configuration of other access points in the cluster.
Access points are supported on the following SRX Series Services Gateways:

Command-Line Interface (CLI)
■
On SRX Series devices, the show security monitoring fpc 0 command is now
available.
The output of this CLI command on SRX Series devices differs from previous
implementations on other devices. Note the following sample output:
show security monitoring fpc 0
FPC 0
PIC 0
CPU utilization : 0 %
Memory utilization : 65 %
Current flow session : 0
Max flow session : 131072
NOTE: When SRX Series devices operate in packet mode, flow sessions will not be
created and current flow session will remain zero as shown in the sample output
above. The maximum number of sessions will differ from one device to another. On
SRX3400, SRX3600, SRX5600, AND SRX5800 devices, the output will include two
more lines: SPU current cp session and SPU max cp session.
■
On SRX210 devices with Integrated Convergence Services, TDM configuration
change might interrupt existing TDM calls if any MPIMs are configured. The voice
calls through the MPIM do not work. Run the CLI restart rtmd command after
making a configuration change to the MPIM ports.
■
On SRX210 devices with Integrated Convergence Services, registrations do not
work when PCS is configured and removed thorough the CLI. The dial tone
dissappears when the analog station calls the SIP station. As a workaround, either
run the rtmd restart command or restart the device.

Configuration
■
142
Routers
■
J Series devices no longer allow a configuration in which a tunnel's source or
destination address falls under the subnet of the same logical interface’s address.
■
■
On SRX100, SRX210, SRX240 and, SRX650 devices, the current JUNOS Software
default configuration is inconsistent with the one in Secure Services Gateways,
thus causing problems when users migrate to SRX Series devices. As a
workaround, users should ensure the following steps are taken:
■
The ge-0/0/0 interface should be configured as the Untrust port (with the
DHCP client enabled).
■
The rest of the on-board ports should be bridged together, with a VLAN IFL
and DHCP server enabled (where applicable).
■
Default policies should allow trust->untrust traffic.
■
Default NAT rules should apply interface-nat for all trust->untrust traffic.
■
DNS/Wins parameters should be passed from server to client and, if not
available, users should preconfigure a DNS server (required for download of
security packages).
The default values for IKE and IPsec security association (SA) lifetimes for standard
VPNs have been changed in this release:
■
The default value for the lifetime-seconds configuration statement at the [edit
security ike proposal proposal-name] hierarchy level has been changed from
3600 seconds to 28,800 seconds.
■
The default value for the lifetime-seconds configuration statement at the [edit
security ipsec proposal proposal-name] hierarchy level has been changed from
28,800 seconds to 3600 seconds.
Flow and Processing
■
On SRX Series devices, the factory default for the maximum number of backup
configurations allowed is five. Therefore, you can have one active configuration
and a maximum of five rollback configurations. Increasing this backup
configuration number will result in increased memory usage on disk and
increased commit time.
To modify the factory defaults, use the following commands:
root@host# set system max-configurations-on-flash number
root@host# set system max-configuration-rollbacks number
where max-configurations-on-flash indicates backup configurations to be stored
in the configuration partition and max-configuration-rollbacks indicates the
maximum number of backup configurations.
■
On J Series devices, the following configuration changes must be done after
rollback or upgrade from JUNOS Release 10.1 to 9.6 and earlier releases.
■
Rename lsq-0/0/0 to ls-0/0/0 in all its occurrences.
■
Remove fragmentation-map from the [class-of-service] hierarchy level and
from [class-of-service interfaces lsq-0/0/0], if configured.
■
Remove multilink-max-classes from [ls-0/0/0 unit 0], if configured.
Routers
■
143
■
Remove link-layer-overhead from [ls-0/0/0 unit 0], if configured.
■
If the LFI forwarding class is mapped to no-fragmentation in fragmentation-map
and the configuration hierarchy is enabled on lsq-0/0/0 in JUNOS Release
10.1, then
■
Add interleave-fragments under [ls-0/0/0 unit 0]
■
Adjust classifier configured for LFI on lsq-0/0/0 under [class-of-service]
to classify packets to Q2
If the aforementioned instructions are not followed, the bundle will be incorrectly
processed.
■
On SRX Series devices, to minimize the size of system logs, the default logging
level in the factory configuration has been changed from any any to any critical.
■
On SRX3000 and SRX5000 line devices, the set protocols bgp family inet flow and
set routing-options flow CLI statements are no longer available, because BGP flow
spec functionality is not supported on these devices.
■
On SRX100, SRX210, SRX240, and SRX650 devices, the autoinstallation
functionality on an interface enables a DHCP client on the interface and remains
in the DHCP client mode. In previous releases, after a certain period, the interface
changed from being a DHCP client to a DHCP server.
■
On SRX5600 and SRX5800 devices, while running commands in IDP, ensure
that you provide the service field values for custom attack definitions in lowercase.
In the following example, the protocol service field value udp is specified in
lowercase:
set security idp custom-attack temp severity info attack-type signature context packet
direction any pattern .* protocol udp destination-port match equal value 1333
144
Routers
■
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, for brute force and
time-binding-related attacks, the logging is to be done only when the match count
is equal to the threshold. That is, only one log is generated within the 60-second
period in which the threshold is measured. This process prevents repetitive logs
from being generated and ensures consistency with other IDP platforms like
IDP-standalone.
■
On SRX Series and J Series devices, the IDP ip-action statement is now supported
on TCP, UDP, and ICMP flows. When the ip-action target is service, the ip-action
flow is applied if the traffic matches the values specified for protocol, destination
port, source address, and destination address. However, for ICMP flows, the
destination port is 0, so that any ICMP flow matching protocol, source address,
and destination address is blocked. For more information, see the Junos OS CLI
Reference.
■
On SRX3400 and SRX3600 devices in Layer 2 and Layer 3 integrated mode,
mode, 30 percent to 40 percent of the logs created in IDP are not exited from
IDP. In Layer 2 and Layer 3 dedicated mode, the logs are exited properly.
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, to add the Predefined
Attacks and Predefined Attack Groups, users do not need to type the attack
names. Instead, users can select attacks from the Predefined Attacks and
Predefined Attack Group lists and click the left arrow to add them.
■
On SRX100, SRX210, SRX240, and SRX650 devices, the LED status (Alarm, HA,
ExpressCard, Power Status, and Power) shown in the front panel for Chassis
View does not replicate the exact status of the device.
J-Web
Management and Administration
■
On SRX5600 and SRX5800 devices running a previous release of JUNOS Software,
security logs were always timestamped using the UTC time zone. In JUNOS
Release 10.1, you can use the set system time-zone CLI command to specify the
local time zone that the system should use when timestamping the security logs.
If you want to timestamp logs using the UTC time zone, use the set system
time-zone utc and set security log utc-timestamp CLI statements.
■
Configuring the External CompactFlash card on SRX650 Services Gateways:
The SRX650 Services Gateway includes 2-GB CompactFlash storage devices:
■
The Services and Routing Engine (SRE) contains a hot-pluggable
CompactFlash (external CompactFlash) storage device used to upload and
download files.
■
The chassis contains an internal compact flash used to store the operating
system.
By default, only the internal CompactFlash is enabled, and an option to take a
snapshot of the configuration from the internal CompactFlash to the external
compact flash is not supported. This can be done only by using a USB storage
device.
To take a snapshot on the external CompactFlash:
1.
Take a snapshot from the internal CompactFlash to the USB storage device
using the request system snapshot media usb CLI command.
2.
Reboot the device from the USB storage device by using the request system
reboot media usb command.
3.
Go to the U-boot prompt. For more information, see the "Accessing the
U-Boot Prompt" section in the JUNOS Software Administration Guide.
4.
At the U-boot prompt, set the following variables:
set ext.cf.pref 1

5.
Once the system is booted from the USB storage device, take a snapshot on
the external CompactFlash using the request system snapshot media external
command.
NOTE: Once the snapshot has been taken on the external CompactFlash, we
recommend you to set the ext.cf.pref to 0 at the U-boot prompt.
Security
■
J Series devices do not support the authentication order password radius or
password ldap in the edit access profile profile-name authentication-order command.
Instead, use order radius password or ldap password.
■
While configuring the AX411 Access Point on your SRX Series devices, make
sure to enter the WLAN admin password using the set wlan admin-authentication
password command. This command prompts for the password and the password
entered is stored in encrypted form.

NOTE:
■
Without wlan config option enabled, the AX411 Access Points will be managed
with the default password.

Routers
■
■
Changing the wlan admin-authentication password when the wlan subsystem option
is disabled might result in mismanagement of Access Points . You might have
to power cycle the Access Points manually to avoid this issue.
■
The SRX Series devices that are not using the AX411 Access Point can optionally
delete the wlan config option.
■
Accessing the AX411 Access Point through SSH is disabled by default. You can
enable the SSH access using the set wlan access-point <name> external system
services enable-ssh command.

On SRX Series and J Series devices, the following features are not supported when
chassis clustering is enabled on the device:
■
All packet-based protocols, such as MPLS, Connectionless Network Service (CLNS),
and IP version 6 (IPv6)
■

Layer 2 Ethernet switching
The factory default configuration for SRX100, SRX210, and SRX240 devices
automatically enables Layer 2 Ethernet switching. Because Layer 2 Ethernet
switching is not supported in chassis cluster mode, for these devices, if you
use the factory default configuration, you must delete the Ethernet switching
configuration before you enable chassis clustering.
CAUTION: Enabling chassis clustering while Ethernet switching is enabled is not a
supported configuration. Doing so might result in undesirable behavior from the
devices, leading to possible network instability.
■
147
The default configuration for other SRX Series devices and all J Series devices
does not enable Ethernet switching. However, if you have enabled Ethernet
switching, be sure to disable it before enabling clustering on these devices
too.
For more information, see the “Disabling Switching on SRX100, SRX210,
and SRX240 Devices Before Enabling Chassis Clustering” section in the
JUNOS Software Security Configuration Guide.
SRX Series devices have the following limitations:
■
Only two of the 10 ports on each PIC of 40-port 1-Gigabit Ethernet I/O cards
(IOCs) for SRX5600 and SRX5800 devices can simultaneously enable IP address
monitoring. Because there are four PICs per IOC, this permits a total of eight
ports per IOC to be monitored. If more than two ports per PIC on 40-port 1-Gigabit
Ethernet IOCs are configured for IP address monitoring, the commit will succeed
but a log entry will be generated, and the accuracy and stability of IP address
monitoring cannot be ensured. This limitation does not apply to any other IOCs
or devices.
■
SRX3400, SRX3600, SRX5600, and SRX5800 devices have the following
limitations:
■
■
IP address monitoring is not permitted on redundant Ethernet interface LAGs
or on child interfaces of redundant Ethernet interface LAGs.
■
In-service software upgrade (ISSU) does not support version downgrading.
That is, ISSU does not support running an ISSU install of a software release
package earlier or with a smaller release number than the currently installed
version.
■
Only redundant Ethernet interfaces (reth) are supported for IKE external
interface configuration in IPsec VPN. Other interface types can be configured
but IPsec VPN might not work
On SRX3000 and SRX5000 line chassis clusters, screen statistics data can be
gathered on the primary device only.
J Series devices have the following limitations:
■
A Fast Ethernet port from a 4-port Ethernet PIM cannot be used as a fabric link
port in a chassis cluster.
On SRX210 and SRX240 devices, J-Web crashes if more than nine users log in to the
device by using the CLI.
The number of users allowed to access the device is limited as follows:
148
■
■
For SRX210 devices: four CLI users and three J-Web users
■
For SRX240 devices: six CLI users and five J-Web users
Dynamic VPN
SRX100, SRX210, and SRX240 devices have the following limitations:
■
The IKE configuration for the dynamic VPN client does not support the
hexadecimal preshared key.
■
The dynamic VPN client IPsec does not support the Authentication Header (AH)
protocol and the Encapsulating Security Payload (ESP) protocol with NULL
authentication.
■
When you log in through the Web browser (instead of logging in through the
dynamic VPN client) and a new client is available, you are prompted for a client
upgrade even if the force-upgrade option is configured. Conversely, if you log in
using the dynamic VPN client with the force-upgrade option configured, the client
upgrade occurs automatically (without a prompt).
■
On SRX Series devices, data plane logs generated in event mode or in
configurations using set system syslog can increase CPU utilization dramatically,
impacting the system stability, especially in chassis cluster mode.
■
Maximum concurrent SSH, Telnet, and Web sessions—On SRX210, SRX240,

when flow is enabled on the device.
■
On SRX5800 devices, network processing bundling is not supported in Layer 2
transparent mode.
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, downgrading is not
supported in low-impact in-service software upgrade (ISSU) chassis cluster

SRX3400 and SRX3600 devices have the following limitations of a simple filter:
■
In the packet processor on an IOC, up to 100 logical interfaces can be applied
with simple filters.
■
In the packet processor on an IOC, the maximum number of terms of all
simple filters is 4000.
■
In the packet processor on an IOC, the maximum number of policers is
4000.
■
In the packet processor on an IOC, the maximum number of
three-color-policers is 2000.
■
The maximum burst size of a policer or three-color-policer is 16 MB.
■
On SRX650 devices, the T1/E1 GPIMs (2 or 4 port version) do not work in 9.6R1.
This issue is resolved in JUNOS Release 9.6R2 and JUNOS Release 10.1, but if
you roll back to the 9.6R1 image, this issue is still seen.
■
On SRX650 devices, MAC pause frame and FCS error frame counters are not
supported for the interfaces ge-0/0/0 through ge-0/0/3.
■
On SRX240 and SRX650 devices, the VLAN range from 3967 to 4094 falls under
the reserved VLAN address range, and the user is not allowed any configured
VLANs from this range.
■
On SRX650 devices, the last 4 ports of a 24-Gigabit Ethernet switch GPIM can
be used either as RJ-45 or SFP ports. If both are present and providing power,
the SFP media is preferred. If the SFP media is removed or the link is brought
down, then the interface will switch to the RJ-45 medium. This can take up to
15 seconds, during which the LED for the RJ-45 port might go up and down
intermittently. Similarly when the RJ-45 medium is active and an SFP link is
brought up, the interface will transition to the SFP medium, and this transition
could also take a few seconds.
■
On SRX Series and J Series devices, the user can use IPsec only on an interface
that resides in the routing instance inet 0. The user will not be able to assign an
internal or external interface to the IKE policy if that interface is placed in a
routing instance other than inet 0.
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, the following multicast
IPv6 and MVPN CLI commands are not supported. However, if you enter these

On SRX210 devices, the USB modem interface can handle bidirectional traffic
of up to 19 kbps. On oversubscription of this amount (that is, bidirection traffic
of 20 kbps or above), keepalives not get exchanged, and the interface goes down.
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, application-level
distributed denial-of-service (application-level DDoS) detection does not work if
two rules with different application-level DDoS applications process traffic going
to a single destination application server. When setting up application-level DDoS
rules, make sure you do not configure rulebase-ddos rules that have two different
application-ddos objects while the traffic destined to one application server can
process more than one rule. Essentially, for each protected application server,
you have to configure the (application-level DDoS rules so that traffic destined
for one protected server only processes one application-level DDoS rule.
NOTE: Application-level DDoS rules are terminal, which means that once traffic is
processed by one rule, it will not be processed by other rules.
The following configuration options can be committed, but they will not work
properly:
source-zone
destination-zone
destination-ip
service
application-ddos
Application Server
source–zone-1
dst-1
any
http
http-appddos1
1.1.1.1:80
source-zone-2

http-appddos2
1.1.1.1:80
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, the application-level
denial-of-service (application-level DDoS) rulebase (rulebase-ddos) does not
support port mapping. If you configure an application other than default, and if
the application is from either predefined JUNOS Software applications or a custom
application that maps an application service to a nonstandard port,
application-level DDoS detection will not work.
When you configure the application setting as default, IDP uses application
identification to detect applications running on standard and nonstandard ports,
hence the application-level DDoS detection would work properly.
■
On SRX210, SRX240, and SRX650 devices, the maximum number of IDP sessions
supported is 16,000.
■
On SRX Series devices, all IDP policy templates are supported except All Attacks.
There is a 100-MB policy size limit for integrated mode and a 150-MB policy size
limit for dedicated mode, and the current IDP policy templates supported are
dynamic, based on the attack signatures being added. Therefore, be aware that
supported templates might eventually grow past the policy-size limit.
On SRX Series devices, the following IDP policies are supported:
■
DMZ_Services
■
DNS_Service
■
File_Server
■
153
■
■
■
Getting_Started
■
IDP_Default
■
Recommended
■
Web_Server
IDP deployed in both active/active and active/passive chassis clusters has the
following limitations:
■
No inspection of sessions that fail over or fail back.
■
The IP address action table is not synchronized across nodes.
■
The Routing Engine (RE) on the secondary node might not be able to reach
networks that are reachable only through a Packet Forwarding Engine (PFE).
■
The SSL session-ID cache is not synchronized across nodes. If an SSL session
reuses a session-ID and it happens to be processed on a node other than the
one on which the session-ID is cached, the SSL session cannot be decrypted
and will be bypassed for IDP inspection.
IDP deployed in active/active chassis clusters has the following limitation:
■
For time-binding scope source traffic, if attacks from a source with more
than one destination have active sessions distributed across nodes, the attack
might not be detected because time-binding counting has a local-node-only
view. Detecting this sort of attack requires an RTO synchronization of the
time-binding state that is not currently supported.
■
On SRX100, SRX210, SRX240, and SRX650 devices, maximum supported entries
in ACS table for is 100,000 entries. However, since the user land buffer has fix
size of 1MB as a limitation, therefore it displays maximum 38837 cache entries.
■
IDP does not allow header checks for nonpacket contexts.
■
On J Series devices, some J-Web pages for new features (for example, the Quick
Configuration page for the switching features on J Series devices) display content
in one or more modal pop-up windows. In the modal pop-up windows, you can
interact only with the content in the window and not with the rest of the J-Web
page. As a result, online Help is not available when modal pop-up windows are
displayed. You can access the online Help for a feature only by clicking the Help
button on a J-Web page.
■
On SRX Series devices, you cannot use J-Web to configure a VLAN interface for
an IKE gateway. VLAN interfaces are not currently supported to be used as IKE
external-interfaces.

NetScreen-Remote
■
On SRX Series devices, NetScreen-Remote is not supported in JUNOS Release
10.1.
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, IKE negotiations
involving NAT traversal do not work if the IKE peer is behind a NAT device that
will change the source IP address of the IKE packets during the negotiation. For
example, if the NAT device is configured with DIP, it changes the source IP
because the IKE protocol switches the UDP port from 500 to 4500.
■
The following describes the maximum numbers of NAT rules and rule sets
supported:
■
For static NAT, up to 32 rule sets and up to 256 rules per rule set can be
configured on a device.
■
For destination NAT, up to 32 rule sets and up to 8 rules per rule set can be
configured on a device.
■
For source NAT, the following are the maximum numbers of source NAT
rules that can be configured on a device:
■
512 for J Series, SRX100, and SRX210 devices
■
1024 for SRX240 and SRX650 devices
■
8192 for SRX3400, SRX3600, SRX5600, and SRX5800 devices
These are systemwide maximums for total numbers of source NAT rules.
There is no limitation on the number of rules that you can configure in a
source NAT rule set as long as the maximum number of source NAT rules
allowed on the device is not exceeded.
■

Performance
■
J Series devices now support IDP and UTM functionality. Under heavy network
traffic in a few areas of functionality, such as NAT and IPsec VPN, performance
is still being improved to reach the high levels to which Juniper Networks is
consistently committed.
■
On J Series devices, the SNMP NAT-related MIB is not supported in JUNOS Release
10.1.
■
On SRX650 devices, if one of the four Gigabit Ethernet ports (ge-0/0/0 through
ge-0/0/3) is linked up at 10 or 100 Mbps, it will not support jumbo frames.
Frames greater than 1500 bytes are dropped.
SNMP
System
Unified Threat Management (UTM)
■
UTM requires 1 GB of memory. If your J2320, J2350, or J4350 device has only
512 MB of memory, you must upgrade the memory to 1 GB to run UTM.
■
On SRX100, SRX210, SRX240, SRX650, and J Series devices, the IRB (VLAN)
interface cannot be used as the underlying interface for Point-to-Point Protocol
over Ethernet (PPPoE).
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, the IPsec NAT-T tunnels
scaling and sustaining issues are as follows:
VLAN
VPNs
■
For a given private IP address, the NAT device should translate both 500
and 4500 private ports to same public IP address.
■
The total number of tunnels from a given public translated IP cannot exceed
1000 tunnels.
WLAN
■
156
■
The following are the maximum numbers of access points that can be configured
and managed from SRX Series devices:
■
SRX210—4 access points
■
Issues in JUNOS Release 10.1 for SRX Series Services Gateways and J Series Services Routers
■
NOTE: The number of licensed access points can exceed the maximum number of
supported access points. However, you can only configure and manage the maximum
number of access points.

The following problems currently exist in SRX Series and J Series devices. The
identifier following the description is the tracking number in our bug database.
■
On SRX5600 devices, if you run the show security alg sip counters command
while doing a bulk call generation, it might bring down the SPU with a flowd
core file error. [PR/292956]
■
On SRX210 devices, the Skinny Client Control Protocol (SCCP)call cannot be set
up after disabling and enabling the SCCP ALG. The call does not go through.
[PR/409586]
■
On SRX3400 and SRX3600 devices, Real-Time Streaming Protocol (RTSP),, TFTP,
and FTP ALG at scale in Layer 2 mode with A/P is not supported in JUNOS Release
10.1. [PR/474140]
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, ALGs are enabled by
default. When security policies are configured with IDP service, there might be
packet drops. When IDP service is enabled through security policy configuration,
we recommend that you disable some or all the ALGs through configuration to
avoid packet drops. For example: set security alg rtsp disable. [PR/474629]
■
157
NOTE: Disabling ALGs will prevent auxiliary or pinhole session creation, and those
sessions might not be permitted based on security policy. The choice depends on
the customer network and what services are being run, whether ALGs need to be
enabled, and whether IDP inspection is required for all or a subset of the traffic.
Authentication
■
On J Series devices, your attempt to log in to the router from a management
device through FTP or Telnet might fail if you type your username and password
in quick succession before the prompt is displayed, in some operating systems.
As a workaround, type your username and password after you see the prompts.
[PR/255024]
■
On J Series devices, after the user is authenticated, if the webauth-policy is deleted
or changed and an entry exists in the firewall authentication table, then an
authentication entry created as a result of webauth will be deleted only if a traffic
flow session exists for that entry. Otherwise, the webauth entry will not be deleted
and will only age out. This behavior will not cause a security breach. [PR/309534]
■
On SRX210 PoE devices, the access point reboots when 100 clients are associated
simultaneously and each one is transmitting 512 bytes packets at 100 pps.
[PR/469418]
■
On SRX650 devices, when an access point is part of a default cluster and you
change the default cluster after the access point is connected to it, the changes
might not be reflected. As a workaround, restart the wireless LAN service.
[PR/497752]
■
On J Series devices in a chassis cluster, the show interface terse command on
the secondary Routing Engine does not display the same details as that of the
primary Routing Engine. [PR/237982]
■
On J4350 Services Routers, because the clear security alg sip call command
triggers a SIP RTO to synchronize sessions in a chassis cluster, use of the
command on one node with the node-id, local, or primary option might result in
a SIP call being removed from both nodes. [PR/263976]
■
On J Series devices, when a new redundancy group is added to a chassis cluster,
the node with lower priority might be elected as primary when the preempt
option is not enabled for the nodes in the redundancy group. [PR/265340]
■
On J Series devices, when you commit a configuration for a node belonging to
a chassis cluster, all the redundancy groups might fail over to node 0. If graceful
protocol restart is not configured, the failover can destabilize routing protocol
adjacencies and disrupt traffic forwarding. To allow the commit operation to
take place without causing a failover, we recommend that you use the set chassis
cluster heartbeat-threshold 5 command on the cluster. [PR/265801]

On J Series devices in a chassis cluster, a high load of SIP ALG traffic might result
in some call leaks in active resource manager groups and gates on the backup
router. [PR/268613]
■
On SRX Series devices in a chassis cluster, configuring the set system process
jsrp-service disable command only on the primary node causes the cluster to go
into an incorrect state. [PR/292411]
■
On SRX Series devices in a chassis cluster, using the set system processes
chassis-control disable command for 4 to 5 minutes and then enabling it causes
the device to crash. Do not use this command on an SRX Series device in a
chassis cluster. [PR/296022]
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, 8-queue configurations
are not reflected on the chassis cluster interface. [PR/389451]
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, the iflset functionality
is not supported for aggregated interfaces such as reth. [PR/391377]
■
On an SRX210 device in a chassis cluster, when you upgrade the nodes,
sometimes the forwarding process might crash and be restarted. [PR/396728]
■
On an SRX210 device in a chassis cluster, when you upgrade to the latest software
image, the interface links do not come up and are not seen in the Packet
Forwarding Engine. As a workaround, you can reboot the device to bring up the
interface. [PR/399564]
■
On an SRX210 device in a chassis cluster, sometimes the reth interface MAC
address might not make it to the switch filter table. This results in the dropping
of traffic sent to the reth interface. As a workaround, restart the Packet
Forwarding Engine. [PR/401139]
■
On an SRX210 device in a chassis cluster, the fabric-monitoring option is enabled
by default. This can cause one of the nodes to move to a disabled state. You can
disable fabric monitoring by using the following CLI command:
set chassis cluster fabric-monitoring disable
[PR/404866]
■
On an SRX210 Low Memory device in a chassis cluster, the firewall filter does
not work on the reth interfaces. [PR/407336]
■
On an SRX210 device in a chassis cluster, the restart forwarding method is not
recommended because when the control link goes through forwarding, the restart
forwarding process causes disruption in the control traffic. [PR/408436]
■
On an SRX210 device in a chassis cluster, there might be a loss of about 5 packets
with 20 Mbps of UDP traffic on an RG0 failover. [PR/413642]
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, no trap is generated
for redundancy group 0 failover. You can check on the redundancy group 0 state
only when you log in to the device. The nonavailability of this information is
caused by a failure of the SNMP walk on the backup (secondary) node. As a
workaround, use a master-only IP address across the cluster so that you can
query a single IP address and that IP address will always be the master for
redundancy group 0. [PR/413719]
■
On an SRX210 device with an FTP session ramp-up rate of 70, either of the
following might disable the secondary node:
■
159
■
Back-to-back redundancy group 0 failover
■
Back-to-back primary node reboot
[PR/414663]
■
If an SRX210 device receives more traffic than it can handle, node 1 either
disappears or is disabled. [PR/416087]
■
On SRX3400, SRX3600, SRX5600, SRX5800, and J Series devices in an
active/active chassis cluster, when the fabric link fails and then recovers, services
with a short time-to-live (such as ALG FTP) stop working. [PR/419095]
■
On SRX5800 devices, SNMP traps might not be generated for the
ineligible-primary state. [PR/434144]
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices in chassis cluster
active/active mode, the J-Flow samplings do not occur and the records are not

On SRX5600 devices, low-impact in-service software upgrade (ISSU) chassis
cluster upgrade does not succeed with the no-old-master-upgrade option when
you upgrade from JUNOS Release 9.6R2 to JUNOS Release 10.1. [PR/471235]
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, the secondary node
displays incorrect interface status after a low-impact in-service software upgrade
(ISSU) from JUNOS Release 9.6R2 to JUNOS Release 10.1R1. [PR/482566]
■
On SRX3400 and SRX3600 devices, chassis cluster upgrades (LICU) with
no-old-master-upgrade from JUNOS Release 9.6R2.11 to 10.0R1.x and from
JUNOS Release 10.0R1.8 to 10.1x.x do not work. [PR/483485]
■
On SRX3600 devices, after you disable and enable the secondary node track,
the IP status remains unreachable. [PR/488890]
■
On SRX5600, SRX5800 devices, the shaping rate doubles during LICU upgrades
after the secondary node becomes the primary node and continues to be the
same doubled value after LICU, when the LICU upgrade is performed for JUNOS
Release 10.0R2 to 10.1R2. [PR/491834]
■
On SRX5600 and SRX5800 devices, the shaping rate is not honored during LICU
upgrades. During LICU upgrades, when the secondary node is upgraded to the
primary node, the shaping rate is doubled and continues to be the same doubled
value after the LICU upgrade is finished. [PR/499481]
■
J4350 and J6350 devices might not have the requisite data buffers needed to
meet expected delay-bandwidth requirements. Lack of data buffers might degrade
CoS performance with smaller (500 bytes or less) packets. [PR/73054]
■
On J Series devices, with a CoS configuration, when you try to delete all the flow
sessions using the clear security flow session command, the WXC application
acceleration platform might fail over with heavy traffic. [PR/273843]
■
On SRX Series devices, class-of-service-based forwarding (CBF) does not work.
[PR/304830]
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, when you change the

Dynamic Host Configuration Protocol (DHCP)
■
On SRX210 and SRX240 devices, when autoinstallation is configured to run on
a particular interface and the default static route is set with options discard,
retain and no-advertise, then the DHCP client running on the interface tries
fetching the configuration files from the TFTP server. During this process, the
UDP data port on the TFTP server might be unreachable. Because of the TFTP
server being unreachable, the autoinstallation process might remain in the
configuration acquisition state. When autoinstallation is disabled, the TFTP might
fail. In this case, you should manually fetch the file from the server or the client
through the relay.
As a workaround, remove the static route options: Discard, Retain, and
no-advertise from the configuration. [PR/454189]
Enhanced Switching
■
On J Series devices, if the access port is tagged with the same VLAN that is
configured at the port, the access port accepts tagged packets and determines
the MAC. [PR/302635]
■
On J Series devices, even when forwarding options are set to drop packets for
the ISO protocol family, the device forms End System-to-Intermediate System
(ES-IS) adjacencies and transmits packets because ES-IS packets are Layer 2
terminating packets. [PR/252957]
■
On SRX Series devices, the show security flow session command currently does
not display aggregate session information. Instead, it displays sessions on a
per-SPU basis. [PR/264439]
■
On J Series devices, OSPF over a multipoint interface connected as a
hub-and-spoke network does not restart when a new path is found to the same
destination. [PR/280771]
■
On SRX Series devices, when traffic matches a deny policy, sessions will not be
created successfully. However, sessions are still consumed, and the
unicast-sessions and sessions-in-use fields shown by the show security flow session
summary command will reflect this. [PR/284299] [PR/397300]
■
On J Series devices, outbound filters will be applied twice for host-generated
IPv4 traffic. [PR/301199]
■
On SRX Series devices, configuring the flow filter with the all flag might result
in traces that are not related to the configured filter. As a workaround, use the
flow trace flag basic with the command set security flow traceoptions flag.

■
■
On SRX240 devices, traffic flooding occurs when multiple multicast IP group
addresses are mapped to the same multicast MAC address because multicast
switching is based on the Layer 2 address. [PR/418519]
■
On SRX650 devices, the input DA errors are not updated when packets are
dropped because of MAC filtering on the following:
■
SRX240 device
■
SRX210 device
■
16-port and 24-port GPIMs
■
SRX650 front-end port
This is due to MAC filtering implemented in hardware.

On SRX5600 and SRX5800 devices, the network processing bundle configuration
CLI does not check if PICs in the bundle are valid. [PR/429780]
■
On SRX650 devices, packet loss is observed when the device interoperates with
an SSG20 with AMI line encoding. [PR/430475]
■
On an SRX210 on-board Ethernet port, an IPv6 multicast packet received gets
duplicated at the ingress. This happens only for IPv6 multicast traffic in ingress.
[PR/432834]
■
On SRX3400 and SRX3600 devices, the ramp rate of session creation is slow at
times for fragmented UDP traffic. [PR/434508]
■
On SRX5800 devices, when there are nonexistent PICs in the network processing
bundle, the traffic is sent out to the PICs and is lost. [PR/434976]
■
The SRX5600 and SRX5800 devices create more than the expected number of
flow sessions with NAT traffic. [PR/437481]

On J Series devices, NAT traffic that goes to the WXC ISM 200 and return back
clear (that is, not accelerated by the WXC ISM 200) does not work. [PR/438152]
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, there is missing
information in the jnxJsFwAuthMultipleFailure trap message. The trap message is
required to contain the username, IP address, application, and trap name, but
the username is missing. [PR/439314]
■
On SRX5800 devices, for any network processing bundle configuration change
to take effect, a reboot is needed. Currently there is no message displayed after
a bundle configuration change. [PR/441546]
■
On SRX5800 devices, the IOC hot swap is not supported with network processing
bundling. If an IOC that has network processing bundling configured gets
unplugged, all traffic to that network processor bundle will be lost. [PR/441961]
■
On SRX5800 devices with interfaces in a network processing bundle, the ICMP
flood or UDP flood cannot be detected at the threshold rate. However, it can be
detected at a higher rate when the per-network processor rate reaches the

■
On SRX210, SRX240, and J6350 devices, the serial interface goes down for long
duration traffic when FPGA 2.3 version is loaded in the device. As a result, the
multilink goes down. This issue is not seen when downgrading the FPGA version
from 2.3 to 1.14. [PR/461471]

■
On SRX100 and SRX210 devices, every time the VDSL2 PIM is restarted in the
ADSL mode, the first packet passing through the PIM will be dropped. This occurs
because there is a bug in the SAR engine, which will not set the ATM connection
until the first packet has been dropped due to no ATM connection. [PR/493099]
■
The destination and destination-profile options for address and
unnumbered-address within family inet and inet6 are allowed to be specified

the firewall DSCP value. [PR/297437]
■
On SRX5600 and SRX5800 devices, when the device is processing heavy traffic,
the show security idp status operational command might fail. As a result, IDP
flow, session, and packet statistics do not match firewall statistics. [PR/389501]
[PR/388048]
■
The SRX210 device supports only one IDP policy at any given time. When you
make changes to the IDP policy and commit, the current policy is completely
removed before the new policy becomes effective. During the update, IDP will
not inspect the traffic that is passing through the device for attacks. As a result,
there is no IDP policy enforcement. [PR/392421]

Engine (500 MB) is reached. [PR/449731]
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices in
maximize-idp-sessions mode, there is an IPC channel between two data plane
processes. The channel is responsible for transferring the "close session" message
(and other messages) from the firewall process to the IDP process. Under stress

When an SRX Series device running JUNOS Release 10.1 (Layer 2
access-integrated mode) is rolled back to the JUNOS Release 9.6 image, the DUT

On SRX3400, SRX3600, SRX5600, and SRX5800 devices, the application-level
distributed denial-of-service (application-level DDoS) rulebase (rulebase-ddos)
does not support port mapping. If you configure an application other than default,
and if the application is from either predefined JUNOS Software applications or
a custom application that maps an application service to a nonstandard port,
application-level DDoS detection will not work. When you configure the
application setting as default, IDP uses application identification to detect
applications running on standard and nonstandard ports, hence the
application-level DDoS detection works properly. [PR/472522]
■
SRX3400, SRX3600, SRX5600, and SRX5800 devices support 4-byte autonomous
system (AS) for BGP configuration. However, the J-Flow template versions 5 and

Power over Ethernet (PoE)
■
On SRX240 and SRX210 devices, the output of the PoE operational commands
takes roughly 20 seconds to reflect a new configuration or a change in status of
the ports. [PR/419920]
■
On SRX210 and SRX240 devices, the deactivate poe interface all command does
not deactivate the PoE ports. Instead, the PoE feature can be turned off by using
the disable configuration option. Otherwise, the device must be rebooted for the
deactivate setting to take effect. [PR/426772]
■
On SRX210 and SRX240 devices, reset of the PoE controller fails when the restart
chassis-control command is issued and also after system reboot. PoE functionality
is not negatively impacted by this failure. [PR/441798]
■
On SRX210 PoE devices managing AX411 Access Points, the devices might not
be able to synchronize time with the configured NTP Server. [PR/460111]
■
On SRX210 devices, the fourth access point connected to the services gateway
fails to boot with the default Power over Ethernet (PoE) configuration. As a
workaround, configure all the PoE ports to a maximum power of 12.4 watts.
Use the following command to configure the ports:
root#set poe interface all maximum-power 12.4
[PR/465307]
■
On SRX100, SRX210, SRX240, and SRX650 devices, with factory default
configurations the device is not able to manage the AX411 Acess Point. This
might be due to the DHCP default gateway not being set. [PR/468090]

■
On SRX210 PoE devices, high latencies might be observed for the Internet Control
Message Protocol (ICMP) pings between two wireless clients when 32 virtual
access points (VAPs) are configured. [PR/472131]
■
On SRX210 PoE devices, when AX411 Access Points managed by the SRX Series
devices reboot, the configuration might not be reflected onto the AX411 Access
Points. As a result, the Ax411 Access Points retain the factory default
configuration. [PR/476850]
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, the egress filter-based
forwarding (FBF) feature is not supported. [PR/396849]
■
On SRX210, SRX3400, SRX3600, SRX5600, and SRX5800 devices in a chassis
cluster, if the Infranet Controller auth table mapping action is configured as
provision auth table as needed, UAC terminates the existing sessions after Routing
Engine failover. You might have to initiate new sessions. Existing sessions will
not get affected after Routing Engine failover if the Infranet Controller auth table
mapping action is configured as always provision auth table. [PR/416843]
■
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, you should not
configure rulebase-DDoS rules that have two different application-DDoS objects
to run on one destination service because the traffic destined to one application
server can encounter more than one rule. Essentially, for each protected
application server, you have to configure a single application-level DDoS rule.

■
On SRX210 High Memory devices, content filtering provides the ability to block
protocol commands. In some cases, blocking these commands interferes with
protocol continuity, causing the session to hang. For instance, blocking the FETCH
command for the IMAP protocol causes the client to hang without receiving any
response. [PR/303584]
■
On SRX210 High Memory devices, when the content filtering message type is
set to protocol-only, customized messages appear in the log file. [PR/403602]
■
On SRX210 High Memory devices, the express antivirus feature does not send
a replacement block message for HTTP upload (POST) transactions if the current
antivirus status is engine-not-ready and the fallback setting for this state is block.
An empty file is generated on the HTTP server without any block message
contained within it. [PR/412632]
■
On SRX240, SRX650, and J Series devices, Outlook Express is sending infected
mail (with an EICAR test file) to the mail server (directly, not through DUT).
Eudora 7 uses the IMAP protocol to download this mail (through DUT). Mail
retrieval is slow, and the EICAR test file is not detected. [PR/424797]
■
On SRX650 devices operating under stress conditions, the UTM subsystem file
partition might fill up faster than UTM can process and clean up existing
temporary files. In that case, the user might see error messages. As a workaround,

■
On SRX240 High Memory devices, FTP download for>4 MB files does not work
in a two-device topology. [PR/435366]
■
On SRX210, SRX240, and SRX650 devices, the Websense server stops taking
new connections after HTTP stress. All new sessions get blocked. As a
workaround, reboot the Websense server. [PR/435425]
■
On SRX240 devices, if the device is under UTM stress traffic for several hours,
users might get the following error while using a UTM command:
the utmd subsystem is not responding to management requests.
As a workaround, restart the utmd process. [PR/436029]
USB Modem
■
On SRX210 High Memory devices and J6350 devices, packet loss is seen during
rapid ping operations between the dialer interfaces when packet size is more
than 512 Kbps. [PR/484507]
■
On SRX210 High Memory devices, the modem interface can handle bidirectional
traffic of up to 19 Kbps. During oversubscription of 20-Kbps or more traffic, the
keepalive packets are not exchanged and the interface goes down. [PR/487258]
■
On SRX210 High Memory devices, IPv6 is not supported on dialer interfaces
with a USB modem. [PR/489960]
■
On SRX210 High Memory devices, http traffic is very slow through the umd0
interface. [PR/489961]
■
On SRX210 High Memory devices, on multiple resets of the umd0 interface, the
umd0 interface keeps flapping if the d10 (dialer) interface on either the dial-in
or dial-out interface goes down because no keepalive packets are exchanged. As
a workaround, increase the ATS0 value to 4 or greater. [PR/492970]
■
On SRX210 High Memory devices and J6350 devices, the D10 link flaps during
long-duration traffic of 15 Kbps and also when packet size is 256 Kbps or more.
[PR/493943]
■
On SRX650 devices, when VLAN tagging is configured and traffic is sent, the
output of show interfaces ge-0/0/1 media detail VLAN tagged frame count is not
shown. [PR/397849]
■
On SRX240, SRX650, J4350, and J6350 devices, tagged frames on an access
port with the same VLAN tag are not dropped. [PR/414856]
■
On SRX100, SRX210, and SRX240 devices, the packets are not being sent out
of the physical interface when the VLAN ID associated with the VLAN interface
is changed. As a workaround, you need to clear the ARP. [PR/438151]

On SRX5600 devices, the shared IKE limit for IKE users is not currently enforced.
More users than are specified in the shared IKE limit are able to establish
IKE/IPsec tunnels. [PR/288551]
■
On SRX210 and SRX240 devices, concurrent login to the device from a different
management systems (for example, laptop or computers) are not supported.
The first user session will get disconnected when a second user session is started
from a different management system. Also, the status in the first user system is
displayed incorrectly as “Connected”. [PR/434447]
■
On SRX Series and J Series devices, the site-to-site policy-based VPNs in a three
or more zone scenario will not work if the policies match the address “any”,
instead of specific addresses, and all cross-zone traffic policies are pointing to
the single site-to-site VPN tunnel. As a workaround, configure address books in
different zones to match the source and destination, and use the address book
name in the policy to match the source and destination. [PR/441967]
■
On SRX210, SRX240 and SRX650 devices, J-Web online Help displays the list

The “Services Configuration Statement Hierarchy” section in the JUNOS® Software
CLI Reference refers to the JUNOS Services Interfaces Configuration Guide, which has
the following error in the sections “Data Size” and “Configuring the Probe”:
■
The minimum data size required by the UDP timestamp probe is identified as 44

In the “Example: Configuring an IPsec Phase 2 Proposal (CLI)” section of the
Junos OS Security Configuration Guide, the second paragraph of the first example
states that the SA, “. . . terminates after 1800 KB of data pass through it.” It
should instead say, “. . . after 1800 seconds.” The same error is present in the
“Example: Configuring an IPsec Phase 2 Proposal (J-Web Point and Click CLI)”
section.
■
In the “Example: Accommodating End-to-End TCP Communication for J Series
Services Routers” section of the Junos OS Security Configuration Guide, one CLI
command given in the example in both the CLI Quick Configuration and
Step-by-Step Procedure is incomplete. The set security flow tcp-mss all-tcp
command must be followed by the keyword mss value. Therefore, the CLI
example in both cases should read set security flow tcp-mss all-tcp mss 1400.
The same error is present in the “Example: Setting the Maximum Segment Size
for All TCP Sessions for SRX Series Services Gateways (CLI)” section.

The “Understanding Selective Stateless Packet-Based Services” section in the
JUNOS Software Administration Guide states: “The following security features are
not supported with selective stateless packet-based services—stateful firewall
NAT, IPsec VPN, DOS screens, J-flow traffic analysis, WXC integrated security
module, security policies, zones, attack detection and prevention, PKI, ALGs,
and chassis cluster.” This statement is not correct. With selective packet-mode,
traffic that is sent through flow is able to use all of those services, even in a single
VR scenario.
■
Information about secure context and router context has been removed from
the JUNOS Software Administration Guide and the JUNOS Software Security

are supported. The guide should state that only DOCSIS 3.0 US model of DOCSIS
Mini-PIM is supported.
Installing Software Packages
■
The current SRX210 documentation does not include the following information:
On SRX210 devices, the /var hierarchy is hosted in a separate partition (instead
of the root partition). If JUNOS Software installation fails as a result of insufficient
space:
■
1.
Use the request system storage cleanup command to delete temporary files.
2.
Delete any user-created files in both the root partition and under the /var
hierarchy.
The “Installing Software using the TFTPBOOT Method on the SRX100, SRX210,
and SRX650 Services Gateway” section in the JUNOS Software Administration
Guide contains the following inaccuracies:
■
The documentation incorrectly implies that the TFTPBOOT method requires
a separate secondary device to retrieve software from the TFTP server.
■
The documentation should indicate that the TFTPBOOT method does not
work reliably over slow speeds or large latency networks.
■
The documentation indicates that before starting the installation, you only
need to configure the gateway IP, device IP address, and device IP netmask
manually in some cases, when actually you need to configure them manually
in all cases.
■
The documentation should indicate that on the SRX100, SRX210, and SRX240
devices, only the ge-0/0/0 port supports TFTP in uboot, and on the SRX650
device, all front-end ports support TFTP in uboot.
■
Step 2 of the “Installing JUNOS Software Using TFTPBOOT” instructions
should mention that the URL path is relative to the TFTP server’s TFTP root
directory. The instructions should also mention that you should store the
JUNOS Software image file in the TFTP server’s TFTP root directory.
■
The documentation should indicate that the TFTPBOOT method installs
software on the internal flash on SRX100, SRX210, and SRX240 devices,
whereas on SRX650 devices, the TFTP method can install software on the
internal or external CompactFlash card.

The JUNOS Software Administration Guide is missing the following information
about installing software using USB on SRX100, SRX210, SRX240, and SRX650
devices:
You can install or recover the JUNOS Software using USB on SRX100, SRX210,
SRX240, and SRX650 devices. During the installation process, the installation
package from the USB is installed on the specified boot media.
Before you begin the installation, ensure the following prerequisites are met:
■
U-boot and Loader are up and running on the device.
■
USB is available with the JUNOS Software package to be installed on the
device.
To install the software image on the specified boot media:
1.
Go to the Loader prompt. For more information on accessing the Loader
prompt, see “Accessing the Loader Prompt” on page 260 of the JUNOS
Software Administration Guide.
2.
Enter the following command at the Loader prompt:
Loader>install URL
Where URL is file:///package
Example:
Loader>install file:///junos-srxsme-9.4-200811.0-domestic.tgz
When you are done, the file reads the package from the USB and installs the
software package. After the software installation is complete, the device boots
from the specified boot media.
NOTE: USB to USB installation is not supported. Also, on SRX100, SRX210, and
SRX240 devices, the software image will always be installed on NAND flash, but on
SRX650 devices, the software image can be installed either on the internal or external
CompactFlash card based on the boot media specified.

Transceiver Compatibility for SRX Series and J Series Devices
We strongly recommend that only transceivers provided by Juniper Networks be
used on SRX Series and J Series interface modules. Different transceiver types
(long-range, short-range, copper, and others) can be used together on multiport SFP
interface modules as long as they are provided by Juniper Networks. We cannot
guarantee that the interface module will operate correctly if third-party transceivers
are used.
Please contact Juniper Networks for the correct transceiver part number for your
device.
Power and Heat Dissipation Requirements for J Series PIMs
On J Series Services Routers, the system monitors the PIMs and verifies that the PIMs
fall within the power and heat dissipation capacity of the chassis. If power
management is enabled and the capacity is exceeded, the system prevents one or
more of the PIMs from becoming active.
CAUTION: Disabling power management can result in hardware damage if you
overload the chassis capacities.
You can also use CLI commands to choose which PIMs are disabled. For details about
calculating the power and heat dissipation capacity of each PIM and troubleshooting
procedures, see the J Series Services Routers Hardware Guide.
Supported Third-Party Hardware
The following third-party hardware is supported for use with J Series Services Routers
running Junos OS.

Dual-Root Partitioning Scheme Documentation for SRX Series Services Gateways
Dual-Root Partitioning Scheme
JUNOS Release 10.1 supports dual-root partitions on SRX100, SRX210, SRX240, and
SRX650 devices. Dual-root partition allow the SRX Series devices to remain functional
if there is file system corruption and facilitate easy recovery of the corrupted file
system.
SRX Series devices running JUNOS Release 9.6 or earlier support a single-root
partitioning scheme where there is only one root partition. Because both the primary
and backup JUNOS Software images are located on the same root partition, the
system fails to boot if there is corruption in the root file system. The dual-root
partitioning scheme guards against this scenario by keeping the primary and backup
JUNOS Software images in two independently bootable root partitions. If the primary
root partition becomes corrupted, the system will be able to boot from the backup
JUNOS Software image located in the other root partition and remain fully functional.
SRX Series devices that ship with JUNOS Release 10.1 are formatted with dual-root
partitions from the factory. SRX Series devices that are running JUNOS Release 9.6
or earlier can be formatted with dual-root partitions when upgrading to JUNOS Release
10.1.
NOTE: The dual-root partitioning scheme allows the SRX Series devices to remain
functional if there is file system corruption and facilitates easy recovery of the
corrupted file system. Although you can install JUNOS Release 10.1 on SRX100,
SRX210, SRX240, and SRX650 devices with the single-root partitioning scheme, we
strongly recommend the use of the dual-root partitioning scheme.
192
■
Selection of Boot Media and Boot Partition
When the SRX Series device powers on, it tries to boot the JUNOS Software from the
default storage media. If the device fails to boot from the default storage media, it
tries to boot from the alternate storage media.
SRX100, SRX210, SRX240 devices boot from the following storage media (in order
of priority):
1.
Internal NAND flash (default; always present)
2.
USB storage device (alternate)
SRX650 devices boot from the following storage media (in order of priority):
1.
Internal CompactFlash card (default; always present)
2.
External CompactFlash card (alternate)
3.
USB storage device (alternate)
With the dual-root partitioning scheme, the SRX Series device first tries to boot the
JUNOS Software from the primary root partition and then from the backup root
partition on the default storage media. If both primary and backup root partitions of
a media fail to boot, then the SRX Series device tries to boot from the next available
type of storage media. The SRX Series device remains fully functional even if it boots
the JUNOS Software from the backup root partition of storage media.
Important Differences Between Single-Root and Dual-Root Partitioning Schemes
Note the following important differences in how SRX Series devices use the two types
of partitioning systems.
■
With the single-root partitioning scheme, there is one root partition that contains
both the primary and backup JUNOS Software images. With the dual-root
partitioning scheme, the primary and backup copies of JUNOS Software are in
different partitions. The partition containing the backup copy is mounted only
when required.
■
With the dual-root partitioning scheme, when the request system software add
command is performed for a JUNOS Software package, the contents of the other
root partition are erased. The contents of the other root partition will not be valid
unless the installation is completed successfully.
■
With the dual-root partitioning scheme, after a new JUNOS Software image is
installed, add-on packages like jais or jfirmware should be reinstalled as required.
■
With the dual-root partitioning scheme, the request system software rollback CLI
command does not delete the current JUNOS Software image. It is possible to
switch back to the image by using the rollback command again.
■
With the dual-root partitioning scheme, the request system software delete-backup
CLI command does not take any action. The JUNOS Software image in the other
root partition will not be deleted.
■
193
Upgrade Methods
SRX Series devices that ship from the factory with JUNOS Release 10.1 are formatted
with the dual-root partitioning scheme.
Existing SRX Series devices that are running JUNOS Release 9.6 or earlier use the
single-root partitioning scheme. While upgrading these routers to JUNOS Release
10.1, you can choose to format the storage media with dual-root partitions (strongly
recommended) or retain the existing single-root partitioning.
Certain JUNOS Software upgrade methods format the internal media before
installation, whereas other methods do not. To install JUNOS Release 10.1 with the
dual-root partitioning scheme, you must use an upgrade method that formats the
internal media before installation.
The following upgrade methods format the internal media before installation:
■
Installation from the boot loader using a TFTP server
■
Installation from the boot loader using a USB storage device
■
Installation from the CLI using the special partition option (available in JUNOS
Release 10.1)
The following upgrade methods retain the existing partitioning scheme:
■
Installation using the CLI
■
Installation using J-Web
WARNING: Upgrade methods that format the internal media before installation wipe
out the existing contents of the media. Only the current configuration will be
preserved. Any important data should be backed up before starting the process.
NOTE: Once the media has been formatted with the dual-root partitioning scheme,
you can use conventional CLI or J-Web installation methods, which retain the existing
partitioning and contents of the media, for subsequent upgrades.
Upgrading to JUNOS Release 10.1 Without Transitioning to Dual-Root Partitioning
If dual-root partitioning is not desired, use the conventional CLI and J-Web installation
methods, as described in the Junos OS Administration Guide for Security Devices.
Upgrading to JUNOS Release 10.1 with Dual-Root Partitioning
To format the media with dual-root partitioning while upgrading to JUNOS Release
10.1, use one of the following installation methods:
194
■
■
Installation from the boot loader using a TFTP server. This method is preferable
if console access to the system is available and a TFTP server is available in the
network.
■
Installation from the boot loader using a USB storage device. This method is
preferable if console access to the system is available and the system can be
physically accessed to plug in a USB storage device.
■
Installation from CLI using the special partition option. This method is
recommended only when console access is not available. This installation can
be performed remotely.
NOTE: After upgrading to JUNOS Release 10.1, the U-boot and boot loader must be
upgraded for the dual-root partitioning scheme to work properly.
Each of the aforementioned methods of installing JUNOS 10.1 with dual-root
partitioning is described in detail in the following sections:
■
Installing from the Boot Loader Using a TFTP Server on page 195
■
Installing from the Boot Loader Using a USB Storage Device on page 196
■
Installing from the CLI Using the partition Option on page 196
■
Upgrading the Boot Loader on page 197
Installing from the Boot Loader Using a TFTP Server
See the Junos OS Administration Guide for Security Devices for detailed information
on installing JUNOS Software using a TFTP server.
To install JUNOS Release 10.1 from the boot loader using a TFTP server:
1.
Upload the JUNOS Software image to a TFTP server.
2.
Stop the device at the loader prompt and set the following variables:
■
ipaddr
loader> set ipaddr=<IP-address-of-the-device>
■
netmask
loader> set netmask=<netmask>
■
gatewayip
loader> set gatewayip=<gateway-IP-address>
■
serverip
loader> set severip=<TFTP-server-IP-address>
3.
Install the image using the following command at the loader prompt:
■
195
loader> install tftp://<server-ip>/<image-path-on-server>
For example:
loader> install tftp://10.77.25.12/junos-srxsme-10.1R1-domestic.tgz
This will format the internal media and install the new JUNOS Software image
on the media with dual-root partitioning.
4.
Once the system boots up with JUNOS Release 10.1, upgrade the U-boot and
boot loader immediately. See “Upgrading the Boot Loader” on page 197.
Installing from the Boot Loader Using a USB Storage Device
To install JUNOS Release 10.1 from the boot loader using a USB storage device:
1.
Format a USB storage device in MS-DOS format.
2.
Copy the JUNOS Software image onto the USB storage device.
3.
Plug the USB storage device into the SRX Series device.
4.
Stop the device at the loader prompt and use the following command:
loader> install file:///<image-path-on-usb>
For example:
loader> install file:///junos-srxsme-10.1R1-domestic.tgz
This will format the internal media and install the new JUNOS Software image
on the media with dual-root partitioning.
5.
Once the system boots up with JUNOS Release 10.1, upgrade the U-boot and
boot loader immediately. See “Upgrading the Boot Loader” on page 197.
Installing from the CLI Using the partition Option
To install JUNOS Release 10.1 with the partition option:
1.
Upgrade the device to JUNOS Release 10.1 or later using the CLI or J-Web. This
will install the new image with the older single-root partitioning scheme.
2.
After the device reboots with JUNOS Release 10.1, upgrade the boot loader to
version 1.5. See “Upgrading the Boot Loader” on page 197.
3.
Reinstall the 10.1 image from JUNOS CLI using the request system software add
command with the partition option. This will copy the image to the device, then
reboot the device for installation. The device will boot up with the 10.1 image
installed with the dual-root partitioning scheme.
NOTE: This process might take 15–20 minutes. The system will not be accessible
over the network during this time.
196
■
Upgrading the Boot Loader
To upgrade the boot loader to version 1.5:
1.
Upgrade to JUNOS Release 10.1 (with or without dual-root support enabled).
The JUNOS 10.1 image contains the latest boot loader binaries in the following
path: /boot/uboot, /boot/loader.
2.
Enter the shell prompt.
3.
Run the following command from the shell prompt:
bootupgrade –u /boot/uboot –l /boot/loader
Installing JUNOS Release 9.6 or Earlier Release on Systems with Dual-Root
Partitioning
JUNOS Release 9.6 and earlier is not compatible with the dual-root partitioning
scheme. These releases can only be installed if the media is reformatted with
single-root partitioning. Any attempt to install JUNOS Release 9.6 or earlier on a
device with dual-root partitioning without reformatting the media will fail with an
error. You must install the JUNOS Release 9.6 or earlier image from the boot loader
using a TFTP server, USB storage device or CLI partition.
NOTE: You do not need to reinstall the earlier version of the boot loader.
Reinstalling the Single-Root Partition Release Over TFTP
To reinstall JUNOS Software from the boot loader using a TFTP server:
1.
Upload the JUNOS Software image to a TFTP server.
2.
Stop the device at the loader prompt and set the following variables:
■
ipaddr
loader> set ipaddr=<IP-address-of-the-device>
■
netmask
loader> set netmask=<netmask>
■
gatewayip
loader> set gatewayip=<gateway-IP-address>
■
serverip
loader> set severip=<TFTP-server-IP-address>
■
197
3.
Install the image using the following command at the loader prompt:
user@host> install tftp://<server-ip>/<image-path-on-server>
For example:
loader> install tftp://10.77.25.12/junos-srxsme-9.6R1-domestic.tgz
This will format the internal media and install the JUNOS Software image on the
media with single-root partitioning.
Reinstalling the Single-Root Partition Release Using USB
To reinstall JUNOS Software from the boot loader using a USB storage device:
1.
Format a USB storage device in MS-DOS format.
2.
Copy the JUNOS Software image onto the USB storage device.
3.
Plug the USB storage device into the SRX Series device.
4.
Stop the device at the loader prompt and use the following command:
user@host> install file://<image-path-on-usb>
For example:
loader> install file:///junos-srxsme-9.6R1-domestic.tgz
This will format the internal media and install the JUNOS Software image on the
media with single-root partitioning.
Installing from the CLI Using the partition Option
To reinstall JUNOS Release 9.6 with the partition option:
1.
Upgrade the boot loader to version 1.5 if your boot loader is older than it. See
“Upgrading the Boot Loader” on page 197

Reinstall the 9.6 image from JUNOS CLI using the request system software add
command with the partition option. This will copy the image to the device, then
reboot the device for installation. The device will boot up with the 9.6 image
installed with the single-root partitioning scheme.
NOTE: This process might take 15–20 minutes. The system will not be accessible
over the network during this time.
Recovery of the Primary JUNOS Software Image with Dual-Root Partitioning Scheme
If the SRX Series Services Gateway is unable to boot from the primary JUNOS Software
image, and boots up from the backup JUNOS Software image in the backup root
198
■
partition, a message is displayed on the console at the time of login indicating that
the device has booted from the backup JUNOS Software image:
login: user
Password:
***********************************************************************
**
**
**
WARNING: THIS DEVICE HAS BOOTED FROM THE BACKUP JUNOS IMAGE
**
**
**
**
It is possible that the active copy of JUNOS failed to boot up
**
**
properly, and so this device has booted from the backup copy.
**
**
**
**
Please re-install JUNOS to recover the active copy in case
**
**
it has been corrupted.
**
**
**
***********************************************************************
Because the system is left with only one functional root partition, you should
immediately restore the primary JUNOS Software image. This can be done by installing
a new image using the CLI or J-Web. The newly installed image will become the
primary image, and the device will boot from it on the next reboot.
CLI Changes
This section describes CLI changes when the SRX Series device runs JUNOS Release
10.1 with the dual-root partitioning scheme.
■
Changes to the Snapshot CLI on page 199
■
partition Option with the request system software add Command on page 200
Changes to the Snapshot CLI
On an SRX Series device, you can configure the primary or secondary boot device
with a “snapshot” of the current configuration, default factory configuration, or rescue
configuration. The snapshot feature is modified to support dual-root partitioning.
The options as-primary, swap-size, config-size, root-size, var-size, and data-size are not
supported on SRX Series devices.
With the dual-root partitioning scheme, performing a snapshot to a USB storage
device that is less than 1 GB is not supported.
■
199
With the dual-root partitioning scheme, you must use the partition option when
performing a snapshot. If the partition option is not specified, the snapshot operation
fails with a message that the media needs to be partitioned for snapshot.
The output for the show system snapshot CLI command is changed in devices with
dual-root partitions to show the snapshot information for both root partitions:
user@host> show system snapshot media usb
Information for snapshot on
usb (/dev/da1s1a) (primary)
Creation date: Jul 24 16:16:01 2009
JUNOS version on snapshot:
junos
: 10.1I20090723_1017-domestic
Information for snapshot on
usb (/dev/da1s2a) (backup)
Creation date: Jul 24 16:17:13 2009
JUNOS version on snapshot:
junos
: 10.1I20090724_0719-domestic
NOTE: You can use the show system snapshot media internal command to determine
the partitioning scheme present on the internal media. Information for only one root
is displayed for single-root partitioning, whereas information for both roots is
displayed for dual-root partitioning.
NOTE: Any removable media that has been formatted with dual-root partitioning
will not be recognized correctly by the show system snapshot CLI command on
systems that have single-root partitioning. Intermixing dual-root and single-root
formatted media on the same system is strongly discouraged.
partition Option with the request system software add Command
A new partition option is available with the request system software add CLI command.
Using this option will cause the media to be formatted and repartitioned before the
software is installed.
When the partition option is used, the format and install process is scheduled to run
on the next reboot. Therefore, it is recommended that this option be used together
with the reboot option.
For example:
user@host>request system software add junos-srxsme-10.1R1-domestic.tgz no-copy
no-validate partition reboot
Copying package junos-srxsme-10.01R1-domestic.tgz to var/tmp/install
200
■
Maximizing ALG Sessions
Rebooting ...
The system will reboot and complete the installation.
WARNING: Using the partition option with the request system software add CLI
command erases the existing contents of the media. Only the current configuration
is preserved. Any important data should be backed up before starting the process.
On SRX3400, SRX3600, SRX5600, and SRX5800 devices, by default, the session
capacity number for RTSP, FTP, and TFTP ALG sessions is 10,000 per flow SPU. The
maximize-alg-sessions option enables you to increase defaults as follows:
■
RTSP, FTP, and TFTP ALG session capacity: 25,000 sessions per flow SPU
■
TCP Proxy connection capacity: 40,000 sessions per flow SPU
NOTE: Flow session capacity will be reduced to half per flow SPU and the above
capacity numbers will not change on the central point SPU.
You can configure maximum ALG sessions as follows:
security {
forwarding-process {
application-services {
maximize-alg-sessions;
}
}
}
You must reboot the device (and its peer in the chassis cluster) for the configuration
to take effect.
Using Dual Chassis Cluster Control Links: Upgrade Instructions for the Second Routing
Engine
A second Routing Engine is required for each device in a cluster if you are using the
dual control links feature (SRX5000 line only). The second Routing Engine does not
provide backup functionality; its purpose is only to initialize the switch on the Switch
Control Board (SCB). The second Routing Engine must be running JUNOS Release
10.1 or later.
Because you cannot run the CLI or enter configuration mode on the second Routing
Engine, you cannot upgrade the JUNOS Software image with the usual upgrade
commands. Instead, use the master Routing Engine (RE0) to create a bootable USB
storage device, which you can then use to install a software image on the second
Routing Engine (RE1).
■
201
To upgrade the software image on the second Routing Engine (RE1):
1.
Use FTP to copy the installation media into the /var/tmp directory of the master
Routing Engine (RE0).
2.
Insert a USB storage device into the USB port on the master Routing Engine
(RE0).
3.
In the UNIX shell, navigate to the /var/tmp directory:
start shell
cd /var/tmp
4.
Log in as root or superuser:
su [enter]
password: [enter SU password]
5.
Use the following command;
dd if=installMedia of=/dev/externalDrive bs=64k
where
■
externalDrive—Refers to the removable media name. For example, the
removable media name on an SRX5000 line device is da0 for both Routing
Engines.
■
installMedia—Refers to the installation media downloaded into the /var/tmp
directory. For example, install-media-srx5000-10.1R1-domestic.tgz.
The following code example can be used to write the image that you copied to
the master Routing Engine (RE0) in step 1 onto the USB storage device:
dd if=install-media-srx5000-10.1R1-domestic.tgz of=/dev/da0 bs=64k
6.
Log out as root or superuser:
exit
7.
After the software image is written to the USB storage device, remove the device
and insert it into the USB port on the second Routing Engine (RE1).
8.
Move the console connection from the master Routing Engine (RE0) to the second
Routing Engine (RE1), if you do not already have a connection.
9.
Reboot the second Routing Engine (RE1). Use the following command:
# reboot
■
When the following system output appears, press y:
WARNING: The installation will erase the contents of your disks.
Do you wish to continue (y/n)?
■

Upgrade and Downgrade Instructions for JUNOS Release 10.1 for SRX Series Services
To upgrade to JUNOS Release 10.1 or later, your device must be running one of the
following JUNOS Software releases:
■
9.1S1
■
9.2R4
■
9.3R3
■
9.4R3
■
9.5R1 or later
If your device is running an earlier release, upgrade to one of these releases and then
to the 10.1 release. For example, to upgrade from Release 9.2R1, first upgrade to
Release 9.2R4 and then to Release 10.1R2.

EX2200 switch—The EX2200 switch is a fixed-configuration switch that is
available in four models—24-port or 48-port models with either all ports equipped
for Power over Ethernet (PoE) or none of the ports equipped for PoE.
All EX2200 models provide network ports that have 10/100/1000BASE-T Gigabit
Ethernet connectors and uplink ports that support 1-gigabit small form-factor
pluggable (SFP) transceivers for use with fiber connections and copper
connections. For information about software features supported on the EX2200
switch, see EX Series Switch Software Features Overview.
The following optical interfaces are supported on the EX2200 switch:
■
204
■
■
EX-SFP-1GE-T (1000BASE-T, 100 m)
■
EX-SFP-1GE-SX (1000BASE-SX, 220 m, 275 m, 500 m, or 550 m)
■
EX-SFP-1GE-LX (1000BASE-LX, 10 km)
■
EX-SFP-1GE-LH (1000BASE-LH or 1000Base-LH, 70 km)
■
EX-SFP-1FE-FX (100BASE-FX, 2 km)
■
EX-SFP-FE20KT13R15 (100BASE-BX-U, 20 km)
■
EX-SFP-FE20KT15R13 (100BASE-BX-D, 20 km)
New optical transceiver support—The 8-port 10-Gigabit Ethernet SFP+ line
card in EX8200 switches now supports one new optical transceiver:
EX-SFP-10GE-ER (10GBase-ER, 40 km).
Access Control and Port Security
■
Captive portal authentication—Captive portal authentication allows you to
authenticate users on EX Series switches by redirecting Web browser requests
to a login page that requires users to input a username and password before
they are allowed access to the network. In addition to using the feature to control
network access by requiring users to provide information that is authenticated
against a RADIUS server database, you can use it to display an acceptable-use
policy to users before they access your network. An authentication whitelist
allows you to specify MAC addresses that are allowed to bypass authentication.
Bridging, VLANs, and Spanning Trees
■
Proxy ARP—Proxy ARP can be configured on a per-VLAN basis, in either
restricted or unrestricted mode.
■
IPv6 unicast VRF support—EX Series switches now support IPv6 unicast virtual
routing and forwarding (VRF) traffic.
■
Private VLANs—Private VLANs (PVLANs) are now supported on EX8200 switches.
Class of Service (CoS)
■
Port shaping and queue shaping—Port shaping and queue shaping (the
shaping-rate configuration statement) is now available on EX8200 switches.
Infrastructure
■
IPv6 support on EX8200 switches—EX8200 switches now support configuration
of IPv6 addresses.
■
Automatic refreshing of scripts—You can refresh commit, event, and op scripts
automatically using operational mode commands such as request system scripts
refresh-from commit, request system scripts refresh-from event, or request system
scripts refresh-from op.
■
Source gateway IP address selection for relayed DHCP packets—The source
gateway IP address selection for relayed DHCP packets feature allows you to use
the gateway IP address (giaddr) as the source IP address of the switch for relayed
DHCP packets when an EX Series switch is used as the DHCP relay agent.
■
205
Interfaces
■
Unicast reverse-path forwarding support—Unicast reverse-path forwarding
(RPF) is available on EX8200 switches. The unicast RPF feature can be enabled
on specific interfaces on EX8200 switches and supports ECMP traffic.
Layer 2 and Layer 3 Protocols
■
IPv6 Layer 3 multicast routing and forwarding—EX3200 and EX4200 switches
now support IPv6 Layer 3 multicast routing and forwarding, which includes
Multicast Listener Discovery (MLD) version 1 and version 2 to manage multicast
group membership; reverse-path forwarding (RPF) to enable multicast routers
to correctly forward multicast traffic to other multicast routers; Protocol
Independent Multicast sparse mode (PIM SM) and PIM source-specific multicast
(PIM SSM) protocols; and static rendezvous point (RP), bootstrap RP, and
embedded RP to manage RP information for multicast groups.
Management and RMON
■
Real-time performance monitoring (RPM) support on EX8200 switches—RPM
is supported on EX8208 and EX8216 switches.
■
SNMP MIB enhancements—On EX2200 switches, the SNMP agent polls and
gets details of all MIBs.
MPLS
■
MPLS enhancements—On EX3200 and EX4200 switches, MPLS supports class
of service (CoS), IP over MPLS, and fast reroute to reroute the label-switched
path in cases of link failure.
Packet Filters
■
IPv6 support for firewall filters on EX3200 and EX4200 switches—On EX3200
and EX4200 switches, you can apply match conditions to IPv6 traffic on Layer
3 interfaces, aggregated Ethernet interfaces, and loopback interfaces.
The following are the match conditions applicable to IPv6 traffic:
destination-address, destination-port, destination-prefix-list, icmp-code, icmp-type,
interface, next-header, packet-length, source-address, source-port, source-prefix-list,
tcp-established, tcp-flags, tcp-initial, and traffic-class.
The following are the actions and action modifiers applicable to IPv6 traffic:
accept, discard, routing-instance, analyzer, count, forwarding-class, loss-priority, and
policer.
■
206
■
Enhancement to the interface match condition on EX8200 switches—On
EX8200 switches, you can now specify aggregated Ethernet interfaces as match
conditions using the interface match condition. You can configure an ingress or
Changes in Default Behavior and Syntax in JUNOS Release 10.1 for EX Series Switches
egress firewall filter with an aggregated Ethernet interface as a match condition
and apply the firewall filter to ports, VLANs, and Layer 3 interfaces.

Upgrade and Downgrade Issues for JUNOS Release 10.1 for EX Series Switches
on page 218
The following changes in system behavior, configuration statement usage, or
operational mode command usage have occurred since the previous release and
might not yet be documented in the JUNOS Software for EX Series switches
documentation:
Layer 2 and Layer 3 Protocols
■
EX Series switches now support the show multicast rpf instance instance-name
command.
■
The iso option is not available in the show pfe route command because it is not
supported on EX Series switches.
■
On EX Series switches, the sip-server statement in the [edit system services dhcp]
hierarchy is now supported, allowing explicit configuration of SIP server addresses
for DHCP servers.
Infrastructure
■
On EX3200 switches and EX4200 switches, the request system power-off
other-routing-engine and the request system power-off both-routing-engines
commands are disabled.
■
The output of the show chassis hardware command for EX3200 switches and
EX4200 switches has been changed. The Description field in the output now
displays SFP-100-LX40 for the 100Base-LH interface and SFP-100-LH for the
100Base-ZX interface.
■
If you enable PIM on all interfaces using the interface all command, it is not
enabled on the me0 and vme interfaces by default. Therefore you do not need
■
207
to explicitly disable PIM on these management interfaces. Previously, enabling
PIM on all interfaces caused it to be enabled on these management interfaces.

Limitations in JUNOS Release 10.1 for EX Series Switches
This section lists the limitations in JUNOS Release 10.1R4 for EX Series switches.
Access Control and Security
■
When you have configured more than 1024 supplicants on a single interface,
802.1X authentication might not work as expected and the 802.1X process
(dot1xd) might fail.
■
On EX8200 switches, classification of packets using ingress firewall filter rules
with forwarding-class and loss-priority configurations does not rewrite the DSCP
or 802.1p bits. Rewriting of packets is determined by the forwarding-class and
loss-priority values set in the DSCP classifier applied on the interface.
■
On EX4200 switches, the traffic is shaped at rates above 500 kbps, even when
the shaping rate configured is less than 500 kbps.
■
When the scheduler map bound to an interface is changed, there might be packet
drops temporarily on all the interfaces bound to the scheduler map while the
configuration change is being implemented.
■
On EX Series switches, when interface ranges or VLAN ranges are used in
configuring firewall filters, egress firewall filter rules take more than 5 minutes
to take effect.
■
IGMP packets are not matched by user-configured firewall filters.
Class of Service
Firewall Filters
208
■
Infrastructure
■
If you configure interface parameters on an EX3200 or EX4200 switch running
JUNOS Release 9.2 or Release 9.3 for EX Series switches and then attempt to
upgrade to a later release or a later version of Release 9.3 than the one that is
currently installed, the switch might display the following error message: init:
interface-control is thrashing , not restarted. As a workaround, on the interfaces
you had previously configured, configure no-auto-negotiation and set the link
mode to full-duplex, then commit the revised configuration.
■
The RADIUS request sent by an EX Series switch contains both Extensible
Authentication Protocol (EAP) Identity Response and State attributes.
■
On EX Series switches, an SNMP query fails when the SNMP index size of a table
is greater than 128 bytes, because the Net SNMP tool does not support SNMP
index sizes greater than 128 bytes.
■
Spanning-tree, GVRP, or IGMP snooping configuration windows might load slowly
in the J-Web interface. Wait till the windows load completely before entering
information, or some information might get lost.
■
On EX Series switches, the show snmp mib walk etherMIB does not display any
output, even though the etherMIB is supported. This occurs because the values
are not populated at the module level—they are populated at the table level only.
You can issue show snmp mib walk dot3StatsTable, show snmp mib walk
dot3PauseTable, and show snmp mib walk dot3ControlTable commands to display
the output at the table level.
■
When you issue the request system power-off command, the switch halts instead
of turning off power.
■
In the J-Web interface, the Ethernet Switching monitoring page might not display
monitoring details if there are more than 13,000 MAC entries on the switch.
■
In the J-Web interface, changing the port role from Desktop, Desktop and Phone,
or Layer 2 Uplink to another port role might not remove the configurations for
enabling dynamic ARP inspection and DHCP snooping.
■
On EX8200 switches, if IS-IS is enabled on routed VLAN interfaces (RVIs), IS-IS
adjacency states go down and come up after a graceful Routing Engine switchover
(GRES).
■
When an external RADIUS server goes offline and comes back online after some
time, subsequent captive portal authentication requests might fail until the authd
daemon is restarted. As a workaround, configure the revert interval—the time
after which to revert to the primary server—and restart the authd daemon.
■
Momentary loss of an inter-Routing Engine IPC message might trigger the alarm
that displays the message Loss of communication with Backup RE. There is no
functionality affected.
■
209
Interfaces
■
EX Series switches do not support queued packet counters. Therefore, the queued
packet counter in the output of the show interfaces interface-name extensive
command always displays a count of 0 and is never updated.
■
The following message might appear in the system log:
Resolve request came for an address matching on Wrong nh nh:355,
type:Unicast...?
You can ignore this message.

■
On EX3200 and EX4200 switches, when port mirroring is configured on any
interface, the mirrored packets leaving a tagged interface might contain an
incorrect VLAN ID.
■
On EX8200 switches, port mirroring configuration on a Layer 3 interface with
the output configured to a VLAN is not supported.
■
On EX8200 switches, when an egress VLAN that belongs to a routed VLAN
interface (RVI) is configured as the input for a port mirroring analyzer, the
analyzer incorrectly appends a dot1q (802.1Q) header to the mirrored packets
or does not mirror any packets at all. As a workaround, configure a port mirroring
analyzer with each port of the VLAN as egress input.
■
The following interface counters are not supported on routed VLAN interfaces
(RVIs): local statistics, traffic statistics, and transit statistics.
■
EX Series switches do not support IPv6 interface statistics. Therefore, all values
in the output of the show snmp mib walk ipv6IfStatsTable command always display
a count of 0.
■
The show interface detail | extensive command might display double counting of
packets or bytes for the transit statistics and traffic statistics counters. You can
use the counter information displayed under the Physical interface section of the
output.
■
When a virtual management Ethernet (VME) interface is used as a default gateway
and the VME interface is the indirect next hop for any route, the route might not

use an HTTP connection to access the J-Web interface to upload or download a
configuration file. [PR/551200]
■
If you have accessed the J-Web interface using Microsoft Internet Explorer, you
might not be able to commit a configuration when an SSL certificate has been
added to the switch using the CLI editor (Configure >CLI tools > CLI Editor).
As a workaround, you can use Firefox to commit configurations. [PR/552629]

The following are the issues that have been resolved since JUNOS Release 10.1R1
for EX Series switches. The identifier following the descriptions is the tracking number
in our bug database.
■
When both DHCP relay and DHCP snooping are configured on an EX2200 switch,
the DHCP snooping database might not be built on the switch. [PR/480682: This
■
When Multiple VLAN Registration Protocol (MVRP) and MSTP are enabled together
on EX Series switches, convergence does not occur between MVRP and MSTP.
■
On EX4200 switches, with the access interface through which traffic enters the
switch configured as trusted (secure-access-port interface interface-name
■
213
dhcp-trusted), VLAN Spanning Tree Protocol (VSTP) bridge protocol data units
(BPDUs) are sent to the Routing Engine with the learning CPU code 37 instead
of the reserved learning CPU code 306. [PR/468095: This issue has been resolved.]
■
On EX3200 and EX4200 switches with large VLAN configurations (more than
1024 VLANs), stale dynamic VLAN entries might be found in the Ethernet
switching process (eswd) after you delete VLANs or deactivate the Multiple VLAN
Registration Protocol (MVRP). [PR/471647: This issue has been resolved.]
■
On an EX2200 switch, when there is no spanning-tree protocol or redundant
trunk group configured in the network and there is traffic looping, after the
network loop is broken, sometimes MAC learning might not occur. As a
workaround, restart the forwarding (pfem) process. [PR/473454: This issue has
been resolved.]
■
On EX Series switches, in a scaled environment with more than 4000 VLANs,
MVRP advertisements might not be sent intermittently when the VLAN
membership is modified. [PR/475701: This issue has been resolved.]
■
When MVRP and VSTP are enabled together on EX Series switches, convergence
does not occur between MVRP and VSTP. [PR/477019: This issue has been
resolved.]
■
On EX3200 and EX4200 switches, when MVRP dynamic VLAN creation is
disabled, deregistration of VLANs on trunk interfaces does not occur even after
the tag associated with the VLAN has been modified. [PR/479636: This issue has
been resolved.]
■
On EX3200 and EX4200 switches, stale MVRP VLAN membership entries might
be found on blocked interfaces even after MVRP has been deactivated on the
peer switch. [PR/482126: This issue has been resolved.]
■
On an EX2200 switch, when a queue is oversubscribed and you modify a
scheduler with the buffer-size exact option on it such that it reduces the allocated
buffers on the queue, the queue can stop dequeueing packets. As a workaround,
stop traffic going out on the port, and deactivate and reactivate class of service
(CoS). You can also reboot the switch. [PR/481401: This issue has been resolved.]
■
The accept action and the log and syslog action modifiers in the firewall filter
configuration might not work as expected for packets destined for the switch.
■
If an ingress firewall has been configured with a LAG interface match condition
and you delete this firewall configuration, the forwarding (pfem) process might
create a core file. When the pfem process is restarted, it works as expected.
■
On EX3200 and EX4200 switches, if you configure an egress firewall filter with
the match condition source-address or destination-address on a VLAN and its
Class of Service
Firewall Filters
214
■
routed VLAN interface (RVI), the firewall filter might not work properly.
■
On an EX2200 switch, when you add a syslog action modifier to the firewall
filter, the forwarding (pfem) process might create a core file when the filter
binding is changed from an egress VLAN to an ingress VLAN. [PR/495572: This
■
On 48-port SFP line cards used in EX8200 switches, do not install a transceiver
in the first or last port on the bottom row (ports 1 and 47). Transceivers installed
in these ports are difficult to remove. As a workaround, remove the transceiver
by using a small flathead screwdriver or other tool to lift the lock on the
transceiver. [PR/423694: This issue has been resolved.]
■
On an EX2200 switch, if the following message is displayed when the switch is
booting, the installed package might be corrupted:
Hardware
Infrastructure
mount_check: SHA1 (/packages/jkernel-ex-10.1-20090925.0) =
f45dd191b053b608dafecc0ef3ea329c9f85693b
!=5fe72546eed0c0cb83e6addc6709720f56e8b6da
As a workaround, reinstall the image from the loader prompt with the -- format
option set. [PR/433663: This issue has been resolved.]
■
On EX Series switches, MAC addresses not present in the forwarding database
(FDB) because of hash collision are not removed from the Ethernet switching
process (eswd). These MAC addresses do not age out of the Ethernet switching
table even if traffic is stopped completely and are never relearned when traffic
is sent to these MAC addresses, even when there is no hash collision. As a
workaround, clear those MAC addresses from the Ethernet switching table.
■
Though the interface-range configuration statement is not supported under the
[edit groups] hierarchy, an error message might not be displayed when you use
the interface-range statement. [PR/453538: This issue has been resolved.]
■
The DHCP snooping database is not built after graceful Routing Engine switchover
(GRES) is performed twice. Even though packets are coming from the DHCP
server, they are not inserted in the DHCP relay. [PR/461318: This issue has been
resolved.]
■
If an interface is assigned to a VLAN before the interface's stg state is set, loops
might form in the network if a VLAN ID is assigned to the VLAN while the
interface is active in a redundant topology. [PR/472617: This issue has been
resolved.]
■
On EX2200 switches, the MIB OID ipv6Forwarding indicates that IPv6 is supported
even though IPv6 is not supported. The value of the ipv6Forwarding.0 MIB object
is 1. [PR/473128: This issue has been resolved.]
■
On EX8200 switches, after a graceful Routing Engine switchover (GRES), you
can navigate through the Maintenance menu in the LCD even after the
■
215
Maintenance menu in the LCD has been disabled using the set chassis lcd
maintenance-menu disable command. As a workaround, delete the LCD
Maintenance menu configuration using the CLI on the new master switch, and
then disable the LCD Maintenance menu using the set chassis lcd
maintenance-menu disable command. [PR/473597: This issue has been resolved.]
■
In some rare cases, switch bootup fails when the JUNOS Software is loading. The
message Device not ready displays because the NAND flash is not responding.
Workaround: Power cycle the switch. [PR/482026: This issue has been resolved.]
■
If you attempt to set the time zone to Europe/Berlin on a switch with dual Routing
Engines, the commit command might fail. [PR/483273: This issue has been
resolved.]
■
The name of the ethernet-switching-options authentication-whitelist statement will
be changed. The new name is correct in the documentation but is shown in the
CLI as ethernet-switching-options white-list. [PR/487167: This issue has been
resolved.]
■
A memory leak might be present in the pfem SPF database. As a workaround,
you can restart the forwarding (pfem) process. [PR/493197: This issue has been
resolved.]
■
In the J-Web interface, uploading a software package to the switch might not
work properly if you are using Microsoft Internet Explorer Web browser version
7. [PR/424859: This issue has been resolved.]
■
In the J-Web interface, the Edit MSTI window in the Spanning Tree Configuration
page might not display details of an uncommitted interface configuration.
■
In the J-Web interface, the menu on the left side of the J-Web pages and contents
of the J-Web pages might disappear when you double-click the Troubleshoot tab.
As a workaround, click the Dashboard tab or the Configure tab, and then click
the Troubleshoot tab to display the menu and contents of the page. [PR/459936:
This issue has been resolved]
■
In the J-Web interface, in the OSPF Configuration page, no flags are displayed
for the Traceoptions tab in OSPF Global Settings. [PR/461558: This issue has
been resolved.]
■
In the J-Web interface, in the BGP Configuration page (Configuration > Routing
> BGP), if the values entered in the text boxes (for protocols, filename, and
description) contain double quotation marks, the J-Web interface does not allow
you to delete those values. If the value in the Group Name field contains double
quotation marks, the J-Web interface allows you to delete the BGP group name,
but the deleted value reappears when you refresh the BGP Configuration page.
As a workaround, delete the values that contain double quotation marks using
the CLI. [PR/464030: This issue has been resolved.]
■
When you access the J-Web interface using the Mozilla Firefox Web browser and
move a J-Web window (for example, the Add Interface window) over the browser
toolbars, the window appears behind the browser toolbars. After this problem
occurs, the window cannot be moved, because the title bar of the window is not

■
In the J-Web interface, in the OSPF Configuration page (Configuration > Routing
> OSPF), the Traceoptions tab in the Edit Global Settings window does not
display the available flags (tracing parameters). As a workaround, use the CLI to
view the available flags. [PR/475313: This issue has been resolved.]
■
In the J-Web interface Static Routing Configuration page, you might not be able
to delete a configured next-hop address because the Delete button is disabled.
■
In the J-Web interface, the OSPF Monitoring page might display an error message
if there are multiple interfaces or neighbors detected in an autonomous system.

The following pages list the issues in JUNOS Release 10.1R4 for EX Series switches
regarding software upgrade or downgrade:
■
■
■
Upgrading from JUNOS Release 9.2 to Release 10.1 for EX Series
■
Switches
The ARP aging time configuration in the system configuration stanza in JUNOS Release
9.4R1 is incompatible with the ARP aging time configuration in JUNOS Release 9.3R1
or earlier and JUNOS Release 9.4R2 or later. If you have configured system arp
aging-timer aging-time on EX Series switches running JUNOS Release 9.4R1 and upgrade
to JUNOS Release 9.4R2 or later or downgrade to JUNOS Release 9.3R1 or earlier,
the switch will display configuration errors on booting up after the upgrade or
downgrade. As a workaround, delete the arp aging-timer aging-time configuration in
the system configuration stanza and reapply the configuration after you complete
the upgrade or downgrade.
The format of the file in which the Virtual Chassis topology information is stored was
changed in JUNOS Release 9.4. When you downgrade JUNOS Release 9.4 or later
running on EX4200 switches in a Virtual Chassis to JUNOS Release 9.3 or earlier,
make topology changes, and then upgrade to JUNOS Release 9.4 or later, the topology
changes you have made using JUNOS Release 9.3 or earlier are not retained. The
switch restores the last topology change you have made using JUNOS Release 9.4.
Switches
If you are upgrading from JUNOS Release 9.3R1 and have voice over IP (VoIP) enabled
on a private VLAN (PVLAN), you must remove this configuration before upgrading,
to prevent upgrade problems. VoIP on PVLAN interfaces is not supported in releases
later than JUNOS Release 9.3R1.
Upgrading from JUNOS Release 9.2 to Release 10.1 for EX Series Switches
For JUNOS Release 9.3 and later for EX Series switches, during the upgrade process,
the switch performs reference checks on VLANs and interfaces in the 802.1X
configuration stanza. If there are references in the 802.1X stanza to names or tags
of VLANs that are not currently configured on the switch or to interfaces that are not
218
■
configured or do not belong to the ethernet-switching family, the upgrade will fail. In
addition, static MAC addresses on single-supplicant mode interfaces are not supported.
CAUTION: If your Release 9.2 configuration includes any of the following conditions,
revise the configuration before upgrading to Release 10.1. If you do not take these
actions, the upgrade will fail:
■
Ensure that all VLAN names and tags in the 802.1X configuration stanza are
configured on the switch and that all interfaces are configured on the switch and
assigned to the ethernet-switching family. If the VLAN or the interface is not
configured and you try to commit the configuration, the commit will fail.
■
Remove static MAC addresses on single-supplicant mode interfaces. If they exist
and you try to commit the configuration, the commit will fail.
■
In an 802.1X configuration stanza, if authentication-profile-name does not exist
and you try to commit the configuration, the commit will fail.
■
In an 802.1X configuration stanza, broadcast and multicast MAC addresses are
not supported in a static MAC configuration. If they exist and you try to commit
the configuration, the commit will fail.
■
Support for static MAC bypass in single or single-secure mode has been removed.
If static MAC bypass exists and you try to commit the configuration, the commit
will fail.
■
In an 802.1X configuration stanza, the switch will not accept the option vrange
as an assigned VLAN name. If it exists and you try to commit the configuration,
the commit will fail.
■
Enabling 802.1X and the port mirroring feature on the same interface is not
supported. If you enable 802.1X and port mirroring on the same interface and
then attempt to commit the configuration, the commit will fail.
■
In an 802.1X configuration stanza, if the VLAN name or tag specified under dot1x
authenticator static does not exist and you try to commit the configuration, the
commit will fail.
■
If the MSTP configuration contains a VLAN (under protocols mstp msti msti-id)
that does not exist on the switch and you try to commit the configuration, the
commit will fail. Remove the VLAN from the MSTP configuration before you
perform an upgrade.
■
In the interfaces configuration stanza, if no-auto-negotiation is configured but
speed and link duplex settings are not configured under ether-options and you
try to commit the configuration, the commit will fail. If no-auto-negotiation is
configured under ether-options, you must configure speed and link duplex settings.
■
In the ethernet-switching-options configuration, if action is not configured for the
number of MAC addresses allowed on the interface (under secure-access-port
interface interface-name mac-limit in the CLI or in the Port Security Configuration
page in the J-Web interface), and you try to commit the configuration, the commit
will fail. You must configure an action for the MAC address limit before upgrading
from Release 9.2 to Release 10.1.
■
If you have configured a tagged interface on logical interface 0 (unit 0), configure
a tagged interface on a logical interface other than unit 0 before upgrading from
■
219
Release 9.2 to Release 10.1. If you have not done this and you try to commit
the configuration, the commit will fail. Beginning with JUNOS Release 9.3 for EX
Series switches, untagged packets, BPDUs (such as in LACP and STP), and
priority-tagged packets are processed on logical interface 0 and not on logical
interface 32767. In addition, if you have not configured any untagged interfaces,
the switch creates a default logical interface 0.
■
On EX4200 switches, if you have installed advanced licenses for features such
as BGP, rename the /config/license directory to /config/.license_priv before
upgrading from Release 9.2 to Release 9.3 or later. If the switch does not have
a /config/license directory, create the /config/.license_priv directory manually
before you upgrade. If you do not rename the /config/license directory or create
the /config/.license_priv directory manually, the licenses installed will be deleted
after you upgrade from Release 9.2 to Release 9.3 or later.
Switches
When you downgrade a Virtual Chassis configuration from JUNOS Release 10.1 to
Release 9.2 for EX Series switches, member switches might not retain the mastership
priorities that had been configured previously. To restore the previously configured
mastership priorities, commit the configuration by issuing the commit command.
