New Features in Junos OS Release 10.4 for M Series, MX Series, and T Series Routers

The following features have been added to Junos OS Release 10.4. Following the description is the title of the manual or manuals to consult for further information.

Class of Service

•

Hierarchical policer functionality extended to Modular Interface Cards (MICs) (MX Series routers)—Provides hierarchical policer feature parity with Enhanced Intelligent

Queuing (IQE) PICs. This is useful in provideredge applications using aggregate policing for general traffic and when applying a separate policer for premium traffic on a logical or physical interface.

Hierarchical policing on MICs supports the following features:

•

Ingress traffic is first classified into premium and non-premium traffic before a policer is applied.

•

The hierarchical policer contains two policers: premium and aggregate.

Premium trafficis policed by both the premium policer and the aggregate policer. While the premium policer rate-limits premium traffic, the aggregate policer only decrements the credits but does not drop packets. Non-premium traffic is rate-limited by the aggregate policer only, resulting in the following behavior:

•

Premium trafficis assured to have the bandwidth configuredforthe premium policer.

•

Non-premium traffic is policed to the specified rate limit.

For a list of supported MICs, refer to:

http://www.juniper.net/techpubs/en_US/release-independent/junos/topics/reference/ general/mic-mx-series-supported.html.

The logical-interface-policer and physical-interface-policerstatements provide additional hierarchical policer parameters beyond those of the IQE PICs.

You can apply the policer at the inet, inet6, or mpls family level, as follows:

[edit interfaces ge-0/1/0 unit 0 family (inet | inet6 | mpls)] input-hierarchical-policer Test-HP;

New Features in Junos OS Release 10.4 for M Series, MX Series, and T Series Routers

By making a hierarchical policer a logical-interface-policer, you can achieve aggregation within a logical interface. A hierarchical policer configured as a physical-interface-policer supports aggregation within a physical interface. Please note that you still apply the hierarchical policer at the interface and traffic of the families that do not have the hierarchical policer will be policer. This is different from IQE PICs, where you apply a hierarchical policer at the logical or physical interface.

For hierarchical policing of all traffic through a logical interface, a hierarchical policer can be made a logical-interface-policerand applied to all families in the logical interface. Similarly, you can achieve aggregation at the physical interface level.

[Network Interfaces, Class of Service, Policy]

•

DSCP classification for VPLS at the ingress PE (M320 with Enhanced Type III FPC and M120)—Enables you to configure DSCP classification for VPLS at an ingress PE

for encapsulation types vlan-vpls (IQ2 or IQ2E PICs) or ATM II IQ PIC. To configure, define the DSCP classifier at the [edit class-of-service classifiers dscp dscp-name] hierarchy level and apply the DSCP classifier at the [edit interfaces at-fpc-pic-port

unit-logical-unit-numberclassifiers]hierarchylevel.The ATM interfacemust be included

in the routing instance.

[Class of Service]

Interfaces and Chassis

•

Ethernet encapsulation for ATM scheduler (M7i, M10i, M120, and M320 [with Enhanced III FPC] routers)—Enables support for the configuration of an ATM scheduler

map on an Ethernet VPLS over a bridged ATM interface.

[Network Interfaces]

•

Synchronous Ethernet (SyncE) on MX80 routers and MX Series routers with MPCs—Supportsthe Ethernet synchronization messaging channel (ESMC), G.8264-like

clock selection mechanism, and external clocking on MX80 routers and MX Series routers with MPCs. Wireless backhaul and wireline transport services are the primary applications for these features.

The following features are supported:

•

On MX80 routers and MX Series routers, MPCs based on G.8261 and G.8262. This feature does not work on the fixed configuration version of the MX80 routers.

•

All Ethernet type ports are supported on MX80 routers and MX Series routers with MPCs

•

ESMC support as per G.8264

•

CLI command selection of clock sources

•

Monitoring clock sources (maximum of two clock sources can be monitored simultaneously)

•

Revertive and nonrevertive modes

JUNOS OS 10.4 Release Notes

To configure SyncE, include the synchronization statement and its substatements at the [edit chassis] hierarchy level.

[Network Interfaces, Interfaces Command Reference]

•

Enhanced container interface allows ATM children for containers—M Series and T Series routers with ATM2 PICs automatically copy the parent container interface configuration to the children interfaces. Container interfaces do not go down during APS switchovers, thereby shielding upper layers. This feature allows the various ATM features to work over the container ATM for APS.

To specify ATMchildrenwithin a container interface, use the container-list cin statement and (primary | standby) option at the [edit interface at-fpc/pic/slot container] hierarchy level.

To configure a container interface, including its children, use the cin statement and its options at the [edit interface ci-n] hierarchy level.

Container ATM APS does not support inter-chassis APS. MLPPP over ATM CI is also not supported.

[Network Interfaces]

•

Signaling neighboring routers of fabric down on T1600 and T640 routers—The signaling of neighboring routers is supported when a T640 or T1600 router is unable to carry traffic due to all fabric planes being taken offline for one of the following reasons:

•

CLI or offline button pressed

•

Automatically taken offline by the SPMB due to high temperature.

•

PIO errors and voltage errors detected by the SPMB CPU to the SIBs.

The following scenarios are not supported by this feature:

•

All PFEs get destination errors on all planes to all destinations, even with the SIBs staying online.

•

Complete fabric loss caused by destination timeouts, with the SIBs still online.

When chassisd detects that all fabric planes are down, the router reboots all FPCs in the system. When the FPCs come back up, the interfaces will not be created again, since all fabric planes are down.

Once you diagnose and fix the cause of all fabric planes going down, you must then bring the SIBs back online. Bringing the SIBs back online brings up the interfaces.

Fabric down signaling to neighboring routers offers the following benefits:

•

FPCs reboot when the control plane connection to the Routing Engine times out.

•

Extends a simple approach to reboot FPCs when the dataplane blacks out.

When the router transitions from a state where SIBs are online or spare to a state where there are no SIBs are online, then all the FPCs in the system are rebooted. An ERRMSG

New Features in Junos OS Release 10.4 for M Series, MX Series, and T Series Routers

indicates if all fabric planes are down, and the FPCs will reboot if any fabric planes do not come up in 2 minutes.

An ERRMSG indicates the reason for FPC reboot on fabric connectivity loss.

The chassisd daemon traces when an FPC comes online, but a PIC attach is not done because no fabric plane is present.

A CLI warning that the FPCs will reboot is issued when the last fabric plane is taken offline.

You will need to bring the SIBs online after determining why the SIBs were not online. When the first SIB goes online, and link training with the FPCs completes, the interfaces will be created.

Fabric down signaling to neighboring routers functionality is available by default, and no user configuration is required to enable it.

No new CLI commands or alarms are introduced for this feature. Alarms are already implemented for when the SIBs are not online.

[Network Interfaces, System Basics]

•

New enterprise-specific MIB to support digital optical monitoring (MX960, MX480, MX240, and 10-Gigabit Ethernet LAN/WAN PIC with XFP on T640 and T1600 routers)—Junos OS Release 10.4 introduces JUNIPER-DOM-MIB, a new

enterprise-specific MIB to extend MIB support for digital optical monitoring.

JUNIPER-DOM-MIB supports the SNMP Get request for statistics and SNMP Trap

notifications for alarms.

JUNIPER-DOM-MIB is part of the JUNIPER-SMI MIB hierarchy level.

The following MIB objects are supported by JUNIPER-DOM-MIB for digital optical monitoring:

•

jnxDomCurrentTable

•

jnxDomAlarmSet

•

jnxDomAlarmCleared

[SNMP MIBs and Traps Reference]

•

Transition of IPv4 traffic to IPv6 addresses using Dual Stack Lite (DS-Lite)—Adds support for DS-Lite, a means for transitioning IPv4 traffic to IPv6 addresses. This transition will become necessary as the supply of unique IPv4 addresses nears exhaustion. New subscriber homes are allocated IPv6 addresses and IPv6-capable equipment; DS-Lite provides a method for the private IPv4 addresses behind the IPv6 equipment to reach the IPv4 network. An IPv4 host communicateswith a NATendpoint over an IPv6 network using softwires. DS-Lite creates the IPv6 softwires that terminate on the services PIC. Packets coming out of the softwire can then have other services such as NAT applied on them.

[Services Interface, System Basics and Services Command Reference]

JUNOS OS 10.4 Release Notes

•

IPv6 statistics from IQ2 and IQ2E PICs on M320 routers with Enhanced III FPCs and T Series routers—Support statistical accounting for IPv6 traffic traversing the IQ2 and

IQ2E PICs on M320 routers with Enhanced III FPCs and T Series routers.

For IQ2 and IQ2E PIC interfaces,the IPv6 trafficthat is reported will be the total statistics (sum of local and transit IPv6 traffic) in the ingress and egress direction. The IPv6 traffic in the ingress direction will be accounted separately only if the IPv6 family is configured for the logical interface.

Statistics are maintained for routed IPv6 packets in the egress direction.

Byte and packet counters are maintained in the ingress and egress direction.

Differences in IPv6 statistics for IQ2 interfaces and all other interfaces are as follows:

•

IQ2 and IQ2E PIC interfaces report the total statistics for the IPv6 traffic. For other interfaces, the transit statistics are reported.

•

IQ2 and IQ2E PIC interfaces report all IPv6 traffic received on the logical interface. For all other interfaces, only the routed traffic is accounted.

•

IQ2 and IQ2E PIC interfaces report IPv6 statistics for the Layer 2 frame size. For all other interfaces, the Layer 3 packet size is accounted.

The IPv6 statistics can be viewed by logging in to the individual IQ2 PIC or IQ2E PIC, or by using the CLI.

Local statistics are not accounted separately.

To display total IPv6 statistics for IQ2 and IQ2E PICs, use the show interfaces extensive command.

NOTE: The reported IPv6 statistics do not account for the traffic manager

drops in egress direction or the Packet Forwarding Engine/traffic manager drops in the ingress direction. Transitstatistics are not accountedseparately because the IQ2 and IQ2E PICs cannot differentiate between transit and local statistics.

•

100-Gigabit Ethernet PIC interoperability with VLAN steering—Supports interoperability with similar PICs from other vendors using a VLAN steering forwarding option. Previously, the PICs required interconnection to the same model PIC. Interoperabilitywith interfacesfromother vendors was not supported.Junos OS Release

10.4 introduces a new VLAN steering algorithm to configure 100-Gigabit Ethernet PIC interoperation with similar interfaces from other vendors.

Two packet forwarding modes exist under the forwarding-mode statement.SA multicast mode, for proprietary connection of two Juniper Networks 100-Gigabit Ethernet PICs, uses the Ethernet header SA MAC address multicast bit to steer the packets to the appropriate PFE. VLAN steering mode allows the PIC to connect to non-Juniper Networks equipment. On ingress, the PIC compares the outer VLAN ID against a

New Features in Junos OS Release 10.4 for M Series, MX Series, and T Series Routers

user-defined VLAN ID and VLAN mask combination and steers the packet accordingly. Modifying the forwarding mode config reboots the PIC.

VLAN steering overview:

•

In VLAN steering mode, the SA multicast bit is not used for packet steering.

•

In SA multicast bit steering mode, VLAN ID and VLAN mask configuration is not used for packet steering.

•

Configuration of packet forwarding mode and VLAN steering mode uses CLI commands that result in a PIC reboot.

•

There are three tag types for ingress packets:

•

Untagged ingress packet–The packet is sent to PFE1.

•

Ingress packet with one VLAN–The packet forwards based on the VLAN ID.

•

Ingress packet with two VLANs–The packet forwards based on the outer VLAN ID.

•

VLAN rules describe how the router forwards packets. For VLAN steering, you must use one of the two rules available in the CLI:

•

Odd-even rule–Odd number VLAN IDs go to PFE1; even number VLAN IDs go to PFE0.

•

High-low rule–1 through 2047 VLAN IDs go to PFE0; 2048 through 4096 VLAN IDs go to PFE1.

•

When configured in VLAN steering mode, the PIC can be configured in two physical interface mode or in aggregated Ethernet (AE) mode:

•

Two physical interface mode–When the PIC is in two physical interface mode, it creates physical interfaces et-x/0/0:0 and et-x/0/0:1. Each physical interface can configure its own logical interface and VLAN. CLI enforces the followingrestrictions on commit:

•

The VLAN ID configuration must comply with the selected VLAN rule.

•

The previous restriction implies that the same VLAN ID cannot be configured on both physical interfaces.

•

AE mode–In AE mode, the two physical interfaces on the same PIC are aggregated into one AE physical interface. PIC egress traffic is based on the AE internal hash algorithm. PIC ingress traffic steering is based on the customized VLAN ID rule. CLI enforces the following restrictions on commit:

•

The PIC AE working in VLAN steering mode includes both links of this PIC, and only the links of this PIC.

•

The PIC AE working in SA multicast steering mode can include more than one PIC to achieve more than 100-gigabit capacity.

JUNOS OS 10.4 Release Notes

To configure the PIC forwarding mode, include the forwarding-mode statement and its options at the [edit chassis fpc number pic number] hierarchy level.

[Network Interfaces]

•

New control queue disable feature (T Series routers with 10-Gigabit Ethernet PIC with oversubscription)—Providesa new CLI statement for disabling the control queue

feature for the 10-Gigabit Ethernet PIC with oversubscription. To disable the control queue, use the no-pre-classifier statement at the [chassis] hierarchy level.

When the no-pre-classifier statement is set, the control queue feature will be disabled for all ports on that 10-Gigabit Ethernet PIC with oversubscription. Deleting this configuration results in the control queue feature being re-enabled on all the ports of that PIC.

[edit chassis]

fpc 2 {

pic 0 {

no-pre-classifier;

}

NOTE:

1. This feature is applicable in both oversubscribed and line-rate modes.

2. The control queue feature is enabled by default in both oversubscribed

and line-rate modes, which can be overridden by the user configuration.

3. CLI show commands remain unchanged. When the control queue is

disabled, various show queue commands continue to show the control queue in the output. However, all control queue counters are reported as zeros.

4. Enabling or disabling the control queue feature results in the PIC being

bounced (offline/online).

Once the control queue feature is disabled, then the Layer 2 and Layer 3 controlpackets are subject to queue selection based on the BA classification. However, the following control protocol packets are not classified using BA classification, as they might not have a VLAN, MPLS, or IP header:

•

Untagged ARP packets

•

Untagged Layer 2 control packets such as LACP or Ethernet OAM

•

Untagged IS-IS packets

When the control queue feature is disabled, untagged ARP/IS-IS and other untagged Layer 2 control packets will go to the restricted queue corresponding to the forwarding class associated with queue 0.

Layer 2 Ethernet Services

•

Feature support for Trio 3D MPCs and MICs (MX Series routers)—Enables you to configurethe following features through Junos OS Release 9.1: load balancing, Ethernet OAM IEEE 802.1ag Phase 4 MIP support, LLDP, BPDU guard and loop guard, IRB support for interworking of LDP-VPLS and BGP-VPLS, BGP multihoming for Inter-AS VPLS, VPLS Ethernet as a core-facing interface, and limitations on next-hop flooding.

[Layer 2 Configuration]

JUNOS OS 10.4 Release Notes

•

Ethernet CFM support on Trio 3D MPCs and MICs (MX Series routers)—Enables support for Ethernet connectivity fault management (CFM) defined by IEEE 802.1ag for family bridge interfaces.However, MEP configuration is not supported on aggregated Ethernet interfaces.

[Layer 2 Configuration]

MPLS Applications

•

MPLS support on services PICs—Adds MPLS label pop support for services PICs on Junos OS routers. Previously all MPLS traffic would be dropped at the services PIC. No changes are required to CLI configurations for this enhancement. In-service software upgrade (unified ISSU) is supported for tag next hops for MPLS on services PIC traffic, but no support is provided for tags over IPv6 packets or labels on multiple gateways.

[MPLS]

•

Adding descriptions for bypass LSP—You can now add a text describing a bypass LSP using the description option at the [edit protocols rsvp interface interface-name

link-protection bypass bypass-lsp-name] hierarchy level. Enclose any descriptive text

that includes spaces in quotation marks (" "). Any descriptive text you include is displayed in the output of the show rsvp session bypass command and has no effect on the operation of the bypass LSP.

[MPLS]

Multicast

•

Nonstop active routing PIM support for IPv6—Starting with Release 10.4, Junos OS extends the nonstop active routing support for Protocol Independent Multicast (PIM), which is already supported on IPv4, to include the IPv6 address families. The extension of nonstop active routing PIM support to IPv6 enables IPv6 routers to maintain self-generation IDs, multicastsession states, dynamic interface states, list of neighbors, and RPSets across Routing Engine switchovers.

The nonstop active routing support for PIM on IPv6 is similar to the nonstop active routing PIM support on IPv4 except for the following:

•

Nonstop active routing support for PIM on IPv6 supports an embedded rendezvous point (RP) on non-RP routers.

•

Nonstop active routing support for PIM on IPv6 does not support auto-RP,as auto-RP is not supported on IPv6.

For more information about nonstop active routing PIM support on IPv4 and IPv6, see the Junos OS High Availability Configuration Guide.

[High Availability, Multicast]

Routing Policy and Firewall Filters

•

New routing policy system log message—Junos OS Release 10.3 supports a new routing policy system log message. The RPD_PLCY_CFG_NH_NETMASK system log message provides information about ignored netmasks. If you have a policy statement with a term that contains a next-hop address with a netmask, the netmask is ignored.

New Features in Junos OS Release 10.4 for M Series, MX Series, and T Series Routers

The following sample shows the new systemlog message (depending on your network configuration, the type of message you see might be different):

Jun 18 11:22:43 pro5-d rpd[1403]: RPD_PLCY_CFG_NH_NETMASK: Netmask ignored for

next hop: 10.0.0.1/24.

[System Log Messages Reference]

•

Support for displaying the firewall filter version information—You can display the version number of the firewall filter installed in the Routing Engine. The initial version number is 1 and increments by one when you modify the firewall filter settings or an associated prefix action. To show the version number of the installed firewall filter, use the show firewall filter version operational mode command.

[Routing Protocols and Policies Command Reference]

Routing Protocols

•

Point-to-multipoint (P2MP) LSP load balancing across aggregated Ethernet links (M Series except M320)—Enables you to load-balance VPLS multicast and P2MP

multicast traffic over link aggregation. This feature also re-load-balances traffic after a change in the next-hop topology. Next-hop topology changes might include but are not limited to:

•

Layer 2 membership change in the link aggregation

•

Indirect next-hop change

•

Composite next-hop change

No new configuration is required to configure this feature. The load balancing over aggregated links is automatically enabled with this release. For a sample topology and configuration example, see Junos OS Policy Framework Configuration Guide.

[Policy]

•

Support for disabling traps for passive OSPFv2 interfaces—You can now disable interface state change traps for passive OSPF interfaces. Passive OSPF interfaces advertise address information as an internal OSPF route, but do not run the actual protocol. If you are only interested in receiving notifications for active OSPF interfaces, disabling traps for passive OSPF interfaces reduces the number of notificationsreceived and processed by the SNMP server. This allows you to more quickly and easily scan the logs for potential issues on active OSPF interfaces.

To disable and stop receiving notifications for statechanges in a passiveOSPF interface, include the no-interface-state-traps statement at the following hierarchy levels:

•

[edit logical-systems logical-system-name protocols ospf area area-id interface

interface-name]

•

[edit logical-systems logical-system-name routing-instances routing-instance-name

Behavior change for BGP-independent AS domains—Independent domains use the transitive path attribute 128 (attribute set) messages to tunnel the independent domain’s BGP attributes through the internal BGP (IBGP) core. In Junos OS Release

10.3 and later,if you have not configured an independent domain in any routing instance, BGP treats the received attribute 128 message as an unknown attribute. The AS path field in the show route command has been updatedto display an unrecognized attribute and associated hexadecimal value if you have not configured an independent domain. The following is a sample output of the AS path field (depending on your network configuration, the output might be different):

AS path: [12345] I Unrecognized Attributes: 40 bytes AS path: Attr flags e0 code 80: 00 09 eb 1a 40 01 01 00 40 02 08 02 03 fd e9 fd e9 01

2d 40 05 04 00 00 00 64 c0

[Routing Protocols]

•

Support for disabling the attribute set messages on independent AS domains for BGP loop detection—BGP loop detection for a specific route uses the localautonomous

system (AS) domain for the routing instance. By default, all routing instances belong to a single primary routing instance domain. Therefore, BGP loop detection uses the local ASs configured on all of the routing instances. Depending on your network configuration, this default behavior can cause routes to be looped and hidden.

To limit the local ASs in the primary routing instance, configure an independent AS domain for a routing instance. Independent domains use the transitive path attribute 128 (attribute set) messages to tunnel the independent domain’s BGP attributes through the internal BGP (IBGP) core. If you want to configure independent domains to maintain the independence of local ASs in the routing instance and perform BGP loop detection only for the specified local ASs in the routing instance, disable attribute set messages on the independent domain. To disable attribute set messages, include the independent-domain no-attrset statement at the following hierarchy levels:

NAT-PT with DNS ALG support (M Series and T Series routers)—You can configure Domain Name Service (DNS) application-level gateways (ALGs) using NAT with protocol translation (NAT-PT) for IPv6 to IPv4. The implementation is described in RFC 2766 and RFC 2694.

New Features in Junos OS Release 10.4 for M Series, MX Series, and T Series Routers

When you configure NAT-PT with DNS ALGsupport, you must configure two NAT rules. The first NAT rule ensures that the DNS query and response packets are translated correctly. For this rule to work, you must configure a DNS ALG application and reference it in the rule. The second rule is required to ensure that NAT sessions are destined to the address mapped by the DNS ALG.

•

To configure the correct translation of the DNS query and response packets, include the dns-alg-pool dns-alg-pool or dns-alg-prefix dns-alg-prefix statement at the [edit

services nat rule rule-name term term-name then translated] hierarchy level.

•

To configure the DNS ALG application, include the application application-name statement at the [edit applications] hierarchy level, then reference it at the [edit

services nat rule rule-name term term-name from] hierarchy level.

•

To configure destination translation with the DNS ALG address map, use the

use-dns-map-for-destination-translation statement at the [edit services nat rule rule-name term term-name then translated] hierarchy level. This statement correlates

the DNS query or response processing done by the first rule with the actual data sessions processed by the second rule.

You can also control the translation of IPv6 and IPv4 DNS queries in the following ways.

•

For translation control of IPv6 DNS queries, use the

do-not-translate-AAAA-query-to-A-query statement at the [edit applications application application-name] hierarchy level.

•

For translation control of IPv4 queries, use the

do-not-translate-A-query-to-AAAA-query statement at the [edit applications application application-name] hierarchy level.

NOTE: The above two statements cannot be configured together. You can only configure one at a time, but not both.

To check that the flows are established properly, use the show services

stateful-firewall flows command or the show services stateful-firewall conversations

command.

Enhancements to active flow monitoring—Add support for extraction of bandwidth usage information for billing purposes in PIC-based sampling configurations. This capability is supported on M Series, MX Series, and T Series routers and applies only to IPv4 and IPv6 traffic. It is enabled only at the global instance hierarchy level and is not available for per Packet Forwarding Engine instances. To configure the sampling of traffic for billing purposes, include the template as-peer-billing-template-name statement at the [edit forwarding-options sampling family (inet | inet6) output

flow-server server-name version version-number] hierarchy level. To define the peer-AS

billing functionality, include the peer-as-billing-template statement at the [edit services

template fields, see the Junos OS Services Interfaces ConfigurationGuide. You can apply

JUNOS OS 10.4 Release Notes

the existing destination class usage (DCU) policy option configuration for use with this feature.

In addition, the MPLS top label IP address is added as a new field in the existing MPLS-IPv4 flow template. Youcan use this field to gather MPLS forwarding equivalence class (FEC) -based traffic information for MPLS network capacity planning. These ALGs that use Junos Services Framework (JSF) (M Series) is a PIC-only feature applied on sampled traffic and collected by the services PIC or DPC. You can define it for either global or per Packet Forwarding Engine instances for MPLS traffic.

The show services accounting aggregation template operational command has been updated to include new output fields that reflect the additional functionality.

Support for the RPM timestamp on the Services SDK (M Series, MX Series, and T Series)—Real-time performance monitoring (RPM), which has been supported on the

Adaptive Services (AS) interface, is now supported by the Services SDK. RPM is supported on all platforms and service PICs that support the Services SDK.

RPM timestamping is needed to account for any latency in packet communications. You can apply timestamps on the client, the server, or both the client and server. RPM timestamping is supported only with the icmp-ping, icmp-ping-timestamp, udp-ping, and udp-ping-timestamp probe types.

To specify the Services SDK interface, include the destination-interface statement at the [edit services rpm probe probe-owner test test-name] hierarchy level:

Enhancements to port mirroring with next-hop groups (MX Series only)—Adds support for binding up to two port-mirroring instances to the same MX Series Packet FowardingEngine. This enables you to choose multiple mirror destinations by specifying different port-mirroring instances in the filters. Filters must include the

port-mirror-instanceinstance-name statementat the [edit firewall filter filter-name term term-name then] hierarchy level. You must also include the port-mirror-instance instance-name statement at the [edit chassis fpc number] hierarchy level to specify the

FPC to be used.

Inline port mirroring allows you to configure instances that are not bound to the FPC specified in the firewall filter then port-mirror-instance instance-name action. Instead, you can define the then next-hop-group action. Inline port-mirroring aims to decouple the port-mirror destination from the input parameters, such as rate. While the input parameters are programmed in the Switch Interface Board (SIB), the next-hop destination for the mirrored packet is available in the packet itself.

A port-mirroring instance can now inherit input parameters from another instance that specifies it. To configure this option, include the input-parameters-instance

instance-name statement at the [edit forwarding-options port-mirror instance instance-name] hierarchy level.

You can also now configure port mirroring to next-hop groups using a tunnel interface.

Multiple IDP detector support (M120, M320, and MX Series routers with Enhanced III FPCs)—The IDP detector provides information about services, contexts, and

anomalies that are supported by the associated protocol decoder.

The specified routers now support loading multiple IDP detectors simultaneously. When a policy is loaded, it is also associated with a detector. If the new policy being loaded has an associated detector that matches the detector already being used by

JUNOS OS 10.4 Release Notes

the existing policy, the new detector is not loaded and both policies use a single associated detector. However, if the new detector does not match the current detector, the new detector is loaded along with the new policy. In this case, each loaded policy will then use its own associated detector for attack detection. Note that with the specified routers, a maximum of four detectors can be loaded at any given time.

Multiple IDP detector support for the specified routers functions in a similar way to the existing IDP detector support on J Series and SRX Series devices, except for the maximum number of decoder binary instances that are loaded into the process space.

To view the current policy and the corresponding detector version, use the show security

Subscriber Access Management

•

Redirecting HTTP redirect requests (MX Series routers)—Enables support for HTTP traffic requests from subscribers to be aggregated from access networks onto a BRAS router, where HTTP traffic can be intercepted and redirected to a captive portal. A captive portal provides authentication and authorization services for redirected subscribers before granting access to protected servers outside of a walled garden. A walled garden defines a group of servers where access is provided to subscribers without reauthorization through a captive portal. You can use a captive portal page as the initial page a subscriber sees after logging in to a subscriber session and as a page used to receive and manage HTTP requests to unauthorized Web resources. An HTTP redirectremoteserver that resides in a walled garden behind Junos OS routers processes HTTP requests redirected to it and responds with a redirect URL to a captive portal.

To configure HTTP redirect, include the captive-portal-content-delivery statement at the [edit services] hierarchy level.

•

Filter support for service packet counting—You can count service packets, applying them to a specific named counter (__junos-dyn-service-counter), for use by RADIUS.

To enable service packet accounting, specify the service-accounting action at the [edit

firewall family family-name filter filter-name term term-name then] hierarchy level.

[Policy Framework, Subscriber Access]

•

Support for domain maps that apply configuration options based on subscriber domain names (MX Series and M Series routers)—You use domain maps to apply

access options and session-specific parameters to subscribers whose domain name corresponds to the domain map name. You can also create a default domain map that the router uses for subscribers whose username does not include a domain name or has a non-matching domain name.

Domain maps apply subscriber-related characteristics such as profiles (access, dynamic, and tunnel), target and AAA logical system mapping, address pool usage, and PADN routing information.

You configure domain maps at the [edit access domain] hierarchy level.

[Subscriber Access]

•

L2TP LAC support for subscriber management (MX Series routers)—You can now configure an L2TP access concentrator (LAC) on MPC-equipped MX Series routers.

As part of the new L2TP LAC support, you can configure how the router selects a tunnel for a PPP subscriber from among a set of available tunnels. The default tunnel selection method is to fail over between tunnel preference levels. When a PPP user tries to log in to a domain, the router attempts to connect to a destination in that domain by means of the associated tunnel with the highest preference level. If the destination is unreachable, the router then moves to the next lower preference level and repeats the process. No configuration is required for this tunnel selection method.

You can include the fail-over-within-preference statement at the [edit services l2tp] hierarchy level to configure tunnel selection failover within a preference level. With this

JUNOS OS 10.4 Release Notes

method, when the router tries to connect to a destination and is unsuccessful, it selects a new destination at the same preference level. If all destinations at a preference level are marked as unreachable, the router does not attempt to connect to a destination at that level. It drops to the next lower preference level to select a destination. If all destinations at all preference levels are marked as unreachable, the router chooses the destination that failed first and tries to make a connection. If the connection fails, the router rejects the PPP user session without attempting to contact the remote router.

By default, the router uses a round-robin selection process among tunnels at the same preference level. Include the weighted-load-balancing statement at the statement at the [edit servicesl2tp] hierarchy level to specify that the tunnel with the highest weight within a preference is selected until its maximum sessions limit is reached. Then the tunnel with the next highest weight is selected until its limit is reached, and so on. The tunnel with the highest configured maximum sessions value has the greatest weight.

Another feature of L2TP LACs on MX Series routers is the ability to control whether the LAC sends the Calling Number AVP 22 to the LNS. The AVP value is derived from the Calling-Station-Id and identifies the interface that is connected to the customer in the access network. By default, the LAC includes this AVP in ICRQ packets it sends to the LNS. In some networks you may wish to conceal your networkaccessinformation. To prevent the LAC from sending the Calling Number AVP to the LNS, include the

disable-calling-number-avp statement at the [edit services l2tp] hierarchy level.

•

Support for dynamic interface sets (M120, M320, and MX Series routers)—Enables you to configure sets of subscriber interfaces in dynamic profiles. Interface sets are used for providing hierarchical scheduling. Previously, interface sets were supported for interfaces configured in the static hierarchies only.

Supported subscriber interfaces include static and dynamic demux, static and dynamic PPPoE, and static and dynamic VLAN interfaces.

To configure an interface set in a dynamic profile, include the interface-set

interface-set-name statement at the [edit dynamic-profiles interfaces] hierarchy level.

To add a subscriber interface to the set, include the interface interface-name unit

logical-unit-number statement at the [edit dynamic-profiles interfaces interface-set interface-set-name]hierarchy level. Youapplytrafficshaping and scheduling parameters

to the interface-set by including the interface-set interface-set-name and

output-traffic-control-profile profile-name statements at the static [editclass-of-service interfaces] hierarchy level.

A new Juniper Networks VSA (attribute 26-130) is now supported for the interface set name, and includes a predefined variable, $junos-interface-set-name. The VSA is supported for RADIUS Access-Accept messages only; change of authorization (CoA) requests are not supported.

Support for service session accounting statistics (MX Series routers)—You can now capture accounting statistics for subscriber service sessions. Subscriber management supports service session accounting based on service activation and deactivation, as

New Features in Junos OS Release 10.4 for M Series, MX Series, and T Series Routers

well as interim accounting. Time-based accounting is supported for all service sessions. Time and volume-based accounting is supported for classic firewall filter and fast update firewall filter service sessions only.

To provide volume service accounting, the well-known accounting counter (junos-dyn-service-counter) must also be configured for the classic firewall filter and fast update firewall filter service. You define the counter at the [edit firewall family

Subscriber secure policy traffic mirroring supported for L2TP sessions on the LAC (MX Series routers)—The L2TP access concentrator (LAC) implementation supports

RADIUS-initiated per-subscriber traffic mirroring. Both subscriber ingress traffic (from the subscriber into the tunnel) and subscriber egress traffic (from the tunnel to the subscriber) is mirrored at the (subscriber-facing) ingress interface on the LAC. The ingress traffic is mirrored after PPPoE decapsulation and before L2TP encapsulation. The egress traffic is mirrored after L2TP decapsulation. The mirrored packet includes the complete HDLC frame sent to the LNS.

Support for static and dynamic CoS on L2TP LACsubscriber interfaces(M120,M320, and MX Series routers)—Enables you to configure static and dynamic CoS for L2TP

accessconcentrator (LAC) tunnels that transport PPP subscribers at Layer 2 and Layer 3 of the network.

IP and L2TP headers are added to packets arriving at the LAC from a subscriber before being tunneled to the L2TP network server (LNS). Classifiers and rewrite-rules enable you to properly transfer the type-of-service (ToS) value or the 802.1p value from the inner IP header to the outer IP header of the L2TP packet.

For ingress tunnels, you configure fixed or behavior aggregate (BA) classifiers for the PPP interface or an underlying VLAN interface at Layer 2. You can configure Layer 3

JUNOS OS 10.4 Release Notes

classifiers for a family of PPP interfaces. Layer 2 and Layer 3 classifiers can co-exist for a PPP subscriber.

For example, to classify incoming packets for a PPP subscriber, include the classifier

type classifier-name statement at the [edit class-of-service interfaces pp0 unit logical-unit-number] hierarchy level or at the [edit dynamic-profiles class-of-service interfaces pp0 unit logical-unit-number] hierarchy level.

On egress tunnels, you configure rewrite rules to set the ToS or 802.1p value of the outer header. For example, to configure a rewrite-rule definition for an interface with

802.1p encapsulation, include the [rewrite-rule ieee-802.1 (rewrite-name | default) statementat the edit class-of-service interfacesinterface-name unit logical-unit-number] hierarchy level or the [edit dynamic-profiles class-of-service interfaces pp0 unit

logical-unit-number] hierarchy level.

Rewriterulesare applied accordinglytothe forwarding class, packet loss priority (PLP), and code point. The proper transfer of the inner IP header to the outer IP header of the L2TP packet depends on the classifier and rewrite rule configurations.

The following table shows how the classifier and rewrite-rule values transfer from the inner IP header to the outer IP header. The inner IP header (ob001) is classified with assured-forwarding and low loss priority at the ingress interface. Based on the assured-forwarding class and low loss priority in the rewrite rule, the outer IP header is set to ob001 at the egress interface.

L2TP tunnel profiles and AAA support for tunnels in subscriber management (MX Series routers)—You can configure a set of attributes to define an L2TP tunnel for PPP

subscribers. More than one tunnel can be defined for a tunnel profile. Tunnel profiles are applied by a domain map before RADIUS authentication. When the RADIUS Tunnel-Group VSA [26-64] is specified in the RADIUS login, then the RADIUS tunnel profile (group) overrides a tunnel profile specified by the domain map. The tunnel is then configured according to RADIUS tunnel attributes and VSAs.

To configure a tunnel profile, include the tunnel-profile profile-name statement at the

[edit access] hierarchy level. To define a tunnel for a profile, include the tunnel tunnel-id

statement at the [edit access tunnel-profile profile-name] hierarchy level.

Define the attributes of the tunnel at the [edit access tunnel-profile profile-name tunnel

tunnel-id] hierarchy level. You must configure a preference for the tunnel and the IP

address of the LNS tunnel endpoint; all other attributes are optional. Include the

preferencenumber statement to configure the preference. Include the remote-gateway address server-ip-address statement to configure the LNS address.

You can optionally configure the remaining tunnel attributes. Include the

remote-gateway name server-name statement to configure the LNS hostname. Include

the source -gatewayaddressclient-ip-addressstatementand the source-gatewayname

client-name statements to configure the local (LAC) tunnel endpoint. Although you

can configure a medium type (medium type) and protocol type (tunnel tunnel-type) for the tunnel, only the default values of ipv4 and l2tp are supported in this release. Include the identification name statement to configure an assignment ID for the tunnel. Include the max-sessions number statement to configure the maximum number of sessions permitted for the tunnel. Include the secret password statement to configure a cleartext password for authentication by the remote tunnel endpoint (LNS). Finally, you can configure a logical system and routing instance for the tunnel by including the

Dynamic reconfiguration of extended DHCPv6 local server clients (MX Series routers)—You can enable dynamic reconfiguration of DHCPv6 clients to enable the

extended DHCPv6 local server to initiate a client update without waiting for the client to initiate a request. In subscriber management scenarios, a client may need to be quickly updated with its network address and configuration in the event of server changes, such as a restructuring of the service provider’s addressing scheme or a change in the local server IP addressesthat were provided to the clients.

Support for ascend data filters (RADIUS attribute 242) in subscriber firewall filters (MX Series routers)—You can now configure subscriber management to use ascend

data filters (ADFs) to create and apply firewall filters to subscriber traffic. The ADF creates a rule that specifies match conditions on the source and destination IP address, the protocol, and the source and destination port, and also specifies the action to perform (such as accept or discard). The ADF rule also specifies the filter direction, and can optionally provide traffic class and policer information. The router supports ADF rules for family types inet and inet6.

Subscriber management uses dynamic profilestoobtain the ADF rules from the RADIUS server. You can use the new Junos OS predefined variables ($junos-adf-rule-v4 for familyinet and $junos-adf-rule-v6 for inet6) to map ADF rules to Junos OS functionality, or you can statically create ADF rules.

Automaticbinding of stray DHCP requests (MX Series routers)—The default behavior has changed for handling DHCP requests that are received but which have no entry in the database (stray requests). Beginning with Junos OS Release 10.4,automatic binding of stray requests is enabled by default. In Junos OS Release 10.3 and earlier releases, automatic binding of stray requests is disabled by default.

By default, DHCP relay and DHCP relay proxy now attempt to bind the requesting client by creating a database entry and forwarding the request to the DHCP server. If the server responds with an ACK, the client is bound and the ACK is forwarded to the client. If the server responds with a NAK, the database entry is deleted and the NAK is forwarded to the client. This behavior occurs regardless of whether authentication is configured.

In Junos OS Release 10.3 and earlier releases, DHCP relay drops stray requests and forwards a NAK to the client when authentication is configured. Otherwise, DHCP relay attempts to bind the requesting client. In those releases, DHCP relay proxy always

Support for VPLS Layer 2 wholesale configuration in a subscriber access network—Enables you to configure Layer 2 wholesaling within a subscriber access

network. Wholesale access is the process by which an access network provider (wholesaler) 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).

NOTE: In this release, Layer 2 wholesaling supports the use of only the

default logical system using multiple routing instances.

The Juniper Networks Layer 2 wholesale solution is similar to the Layer 3 wholesale solution in many ways. However, when configuring the Juniper Networks Layer 2 wholesale solution, keep the following in mind:

•

No Layer 3 components (address assignment, Layer 3 interfaces, and so on) are involved.

•

S-VLANs must be unique to any Gigabit Ethernet or Aggregated Ethernet interfaces within the entire network (not just unique to one router).

•

Layer 2 wholesale supports only CoA disconnect and variable modification; CoA service activation is not supported.

NOTE: For general information about configuring dynamic wholesale for

your subscriber access network, see the Broadband Subscriber Management Solutions Guide.
