To choose a new Cisco IOS software release by comparing feature support or memory requirements, use Cisco Feature Navigator. Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS and Catalyst OS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or by feature set (software image). Under the release section, you can compare Cisco IOS software releases side by side to display both the features that are unique to each software release and the features that the releases have in common.
Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

Feature Support
Cisco IOS software is packaged in feature sets that consist of software images that support specific platforms. The feature sets available for a specific platform depend on which Cisco IOS software images are included in a release. Each feature set contains specific Cisco IOS features.
Caution Cisco IOS images with strong encryption (including, but not limited to 168-bit [3DES] data encryption feature sets) are subject to U.S. government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay because of U.S. government regulations. When applicable, the purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.
Feature-to-image mapping is available through Cisco Feature Navigator. Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or by feature set (software image). You can compare Cisco IOS software releases side-by-side to display both the features unique to each software release and the features that the releases have in common.

Hot Fabric Sync
The switch fabric module functionality is built into the Supervisor Engine 720 and the RSP720. When a supervisor engine switchover occurs, a fabric switchover also occurs. During this process, the line cards must resynchronize with the new active switch fabric. The Hot Fabric Sync feature, which is enabled by default, keeps both the active and standby fabric in sync at the same time, minimizing the switchover time and thereby minimizing any impact on switch fabric traffic. To verify the fabric sync status of active and standby supervisors, enter the show fabric status command.
This feature is supported on the following chassis: Cisco 7603-S, Cisco 7604, Cisco 7606-S, and Cisco 7609-S. All WAN modules with DFC, SIP-200, SIP-400, and WS-67xx with DFC or CFC are supported.

Configuration Partitioning
The Configuration Partitioning feature provides modularization (“partitioning”) of the running configuration state to provide granular access to the running configuration in Cisco IOS software. This feature is enabled by default in Cisco IOS software images that include this feature.
The Configuration Partitioning feature allows the system to group the configuration state of the device into parts (called “partitions”) so that only the configuration state the user wishes to review is retrieved when a user issues the show running-config partition part command. This feature improves performance for high-end systems with complex configurations because only a part of the running configuration state is processed when generating the running configuration command list, as opposed to the existing method of processing the entire system configuration state.
Default configuration partitions are provided by the introduction of this feature; other Cisco IOS software features may define their own command partitions in later releases.

Interfaces MIB: SNMP Context-based Access
The interface MIB (IF-MIB) has been modified to support context-aware packet information in Virtual Route Forwarding (VRF) environments. VRF environments require that contexts apply to Virtual Private Networks (VPNs) so that clients can be given selective access to the information stored in the IF-MIB. Clients that belong to a particular VRF can access information about the interface from the IF-MIB that belongs to that VRF only. When a client tries to get information from an interface that is associated with a particular context, the client can see only the information that belongs to that context and cannot see IF-MIB information that is associated with interfaces that are connected to another VRF to which it is not entitled. No commands have been modified or added to support this feature.
The IF-MIB supports all tables that are defined in RFC 2863 and the CISCO-IFEXTENSION-MIB.

PBR over TE Tunnel
In Cisco IOS Release 12.2(33)SRB, hardware switching support is introduced for policy-based routing (PBR) packets that are sent over a traffic engineering (TE) tunnel interface on a Cisco 7600 series router. When a TE tunnel interface is configured by using the set interface command in a policy, the packets are processed in hardware. In previous releases, PBR packets that were sent over TE tunnels were fast-switched by route-processor software.

System Logging - EAL4 Certification Enhancements
Note Official EAL4 certification is not claimed by Cisco. This feature is part of current and planned enhancements which may qualify Cisco IOS Software for future certification.
This feature includes the following enhancements:
- The system logging process will now generate “audit start” and “audit stop” messages.
- The system logging process will now generate messages that include the date and time of an event, the type of event, the subject identity, and the outcome (success or failure) of an event.
- Changes to logging parameters will be logged.
- Further enhancements to minimize lost audit records.
VPLS and SVI-Based EoMPLS - Routed Pseudowire Support
The VPLS and SVI-Based EoMPLS - Routed Pseudowire Support feature makes it possible to route (Layer 3) as well as switch (Layer 2) frames for pseudowire connections between provider edge (PE) devices. Both point-to-point PE connections, in the form of Ethernet over MPLS (EoMPLS), and multipoint PE connections, in the form or Virtual Private LAN Services (VPLS), are supported. The ability to route frames to and from these interfaces now makes it possible to terminate a pseudowire into a Layer 3 network (VPN or global) on the same router, or to tunnel Layer 3 frames over a Layer 2 tunnel (EoMPLS or VPLS). The feature supports faster network convergence in the event of a physical interface or device failure through the MPLS Traffic Engineering (MPLS-TE) and Fast Reroute (FRR) features of the network. In particular, the feature enables MPLS TE-FRR protection for Layer 3 multicast over a VPLS domain.
To configure routing support for the pseudowire, configure an IP address and other Layer 3 features for the Layer 3 domain (VPN or global) in the virtual LAN (VLAN) interface configuration. The following example assigns the IP address 10.10.10.1 to the VLAN 100 interface, and enables Multicast PIM. (Layer 2 forwarding is defined by the VFI VFI100.)
ip address 10.10.10.1 255.255.255.0The following example assigns an IP address 20.20.20.1 of the VPN domain VFI200. (Layer 2 forwarding is defined by the VFI VFI200.)

Any Transport over MPLS (AToM) Graceful Restart
Any Transport over MPLS (AToM) Graceful Restart (GR) assists neighboring routers that have MPLS AToM stateful switchover/nonstop forwarding (SSO/NSF) support and Graceful Restart to recover gracefully from an interruption in service. In Cisco IOS Release 12.2(33)SRA, AToM GR functions strictly in helper mode, which means it can only help other routers that are enabled with AToM SSO/NSF and GR to recover. If the router with AToM GR fails, its peers cannot help it recover. AToM GR is based on MPLS Label Distribution Protocol (LDP) Graceful Restart.
Note The NSF/SSO: Any Transport over MPLS and Graceful Restart feature (which is also referred to as “AToM SSO/NSF”) is not supported in Release 12.2(33)SRA. The AToM GR feature that is supported in Release 12.2(33)SRA refers to AToM GR helper mode.

Configuration Logger Persistency
The Configuration Logger Persistency feature implements a “quick save” functionality. The aim is to provide a “configuration save” mechanism in which the time to save changes from the startup configuration is proportional to the size of the incremental changes (with respect to the startup configuration) that must be saved. The persisted commands from the Cisco IOS Configuration logger are used as an extension to the startup configuration. The saved command, which is used as an extension to the startup configuration, provides a quick-save ability. Rather than saving the entire startup configuration, Cisco IOS software now saves just the commands that were entered since the last startup configuration was generated.

Encrypted Multicast over GRE
The Encrypted Multicast over GRE feature, also referred to as secure multicast over Generic Routing Encapsulation (GRE), is integrated in Cisco IOS Software Release 12.2(33)SRA. This feature provides a secure and scalable solution to protect multicast traffic in an enterprise or managed service-provider environment. Each head-end device that is configured with an IP Security (IPsec) Virtual Private Network (VPN) shared port adapter (SPA) can support IPsec encrypted multicast traffic for up to 500 remote tunnels. The practical applications include voice, video, and data broadcast.
Note that this feature requires specific hardware, including a Cisco Catalyst 6500 series switch or a Cisco 7600 series router with an IPsec VPN SPA and a Services SPA Carrier (SSC) module: either an SPA-IPsec-2G or an 7600-SSC-400.

Front Side VRF for the IPsec VPN SPA
The VRF-Aware IPsec feature provides IP Security (IPsec) tunnel mapping to Multiprotocol Label Switching (MPLS) Virtual Private Networks (VPNs). By using the VRF-Aware IPsec feature, you can map IPsec tunnels to Virtual Routing and Forwarding (VRF) instances by using a single public-facing address.
A VRF instance is a per-VPN routing information repository that defines the VPN membership of a customer site attached to the Provider Edge (PE) router. A VRF comprises an IP routing table, a derived Cisco Express Forwarding (CEF) table, a set of interfaces that use the forwarding table, and a set of rules and routing protocol parameters that control the information that is included in the routing table. A separate set of routing and CEF tables is maintained for each VPN customer.
Front Door VRF (FVRF) and Inside VRF (IVRF) are central to understanding the feature.
Each IPsec tunnel is associated with two VRF domains. The outer encapsulated packet belongs to one VRF domain, called the FVRF, while the inner protected IP packet belongs to another domain called the IVRF. Another way of stating the same thing is that the local endpoint of the IPsec tunnel belongs to the FVRF while the source and destination addresses of the inside packet belong to the IVRF.
One or more IPsec tunnels can terminate on a single interface. The FVRF of all these tunnels is the same and is set to the VRF that is configured on that interface. The IVRF of these tunnels can be different and depends on the VRF that is defined in the Internet Security Association and Key Management Protocol (ISAKMP) profile that is attached to a crypto map entry.
In previous releases of the IPsec VPN SPA, VRF-Aware IPsec was supported, but FVRF was not; as of Cisco IOS Release 12.2(33)SRA, FVRF is supported.
For more information about the VRF-Aware IPsec feature, including Front Door VRF, see the VRF-Aware IPSec document:

Secure SNMP Views
The USM, VACM and Community MIBs have information that can potentially be used to gain access to the router using SNMP. Therefore, the USM, VACM, and Community MIBs are excluded from the default SNMP access view so as not to allow remote access unless specifically configured. However, when an SNMP view is created with any parent object identifier (OID) of these MIBs included (for example “internet included”), these MIBs also get included in the view. To increase security, the Secure SNMP Views enhancement excludes these MIBs from SNMP access views even when parent OIDs are included in the view. Prior to this release, when configuring SNMP views with parent OIDs that include the USM, VACM, or Community OIDs, the user was required to explicitly exclude them. For example, the following configuration can be used for excluding security-sensitive MIBs from the SNMP view named “test”:
! - include all MIBs under the parent tree "internet" snmp-server view test internet included
! -- exclude snmpUsmMIB snmp-server view test 1.3.6.1.6.3.15 excluded
! -- exclude snmpVacmMIB snmp-server view test 1.3.6.1.6.3.16 excluded
! -- exclude snmpCommunityMIB snmp-server view test 1.3.6.1.6.3.18 excludedBeginning in Cisco IOS Releases 12.0(26)S and 12.2(2)T, the USM, VACM, and Community MIBs are excluded from any parent OIDs in a configured view by default. If you wish to include these MIBs in a view, you must now explicitly include them.

This section describes limitations and restrictions in Cisco IOS Release 12.2(33)SRE and later releases.
Enhanced Optical Services Modules Not Supported
Beginning with Cisco IOS Release 12.2(33)SRE, Enhanced Optical Service Modules are not supported by Cisco 7600 routers. The following modules are now unsupported:
- OSM Guidelines and Restrictions
- Gigabit Ethernet WAN
- OC-48 Packet over SONET
- OC-48 DPT/Packet over SONET
- OC-12 Packet over SONET
- OC-3 Packet over SONET
- OC-12 Channelized
- CT3/T1 Channelized/Unchannelized
- OC-12 ATM

Limitations and Restrictions in Cisco IOS Release 12.2(33)SRC2
This section describes limitations and restrictions in Cisco IOS Release 12.2(33)SRC2 and later releases.
Cisco 7600 With Redundant Supervisor Cards Running 12.2(33)SRC2
You might experience an error condition with a Cisco 7600 chassis that has redundant supervisor cards running the 12.2(33)SRC2 IOS image and a NAM service blade. The error occurs when you perform a sequential boot of the two supervisor cards because the secondary (standby) supervisor does not go into proper standby mode.
You can find more information about this issue in Field Notice #63179.
- When you boot the two supervisor cards in parallel
- When you boot the standby supervisor card after the primary supervisor is up
- When the Cisco 7600 router runs the 12.2SRC1 image
- When only one supervisor card is installed in the Cisco 7600 chassis
When the primary supervisor functions as a standalone with the secondary supervisor card in RPR mode, the Cisco 7600 chassis functions normally (as if it has a standalone supervisor card). A switchover causes the system to be unavailable for up to three minutes because the secondary supervisor card is not in proper standby mode.
Note When both supervisors are booted simultaneously, the system will go to Hot Standby status. The primary supervisor will reboot when you issue the redun force-switchover command which causes the redundant supervisor to boot up to be the primary and the primary to be the redundant.
This problem requires you to downgrade the IOS image from 12.2SRC2 to 12.2SRC1. Account teams will help you do this if needed.
This problem will be fixed in 12.2SRC3, targeted for mid-January, 2009. When IOS image 12.2SRC3 is available, upgrade the image from 12.2SRC1 to 12.2SRC3 at your earliest opportunity.
Limitations and Restrictions in Cisco IOS Release 12.2(33)SRC
This section describes limitations and restrictions in Cisco IOS Release 12.2(33)SRC and later releases.
Cisco 7200VXR Limitations on Support for Voice Features
Voice-related port adaptors and features are not supported on Cisco 7200VXR platforms in Cisco IOS Release 12.2(33)SRC and later releases. The following port adaptors are not supported on the Cisco 7200VXR:
Cisco 7600 Platform Restrictions for Broadband Support with Cisco IOS Release 12.2SRC
Physical Interface Restrictions
- The Broadband/ISG sessions are only supported on Gigabit (GE) Ethernet interfaces. See the Hardware Restriction section in the documentation for the specific type of GE interfaces that are required.
- The Broadband/ISG sessions are not supported on ATM interfaces.
- The Broadband/ISG sessions are only supported on Cisco 7600 series routers with RSP720 as the supervisor.
- The Broadband/ISG sessions are only supported on Cisco 7600 series routers with 7600-SIP-400 as the subscriber facing line card.
- The Broadband/ISG sessions are only supported on Cisco 7600 series routers with SPA-5X1GE-V2 or SPA-1X10GE-L2 as the subscriber facing port adaptor.
The Broadband/ISG sessions are not supported with following access protocols:
The Broadband/ISG sessions are only supported with access subinterfaces, which were introduced in Cisco IOS Release 12.2(33)SRB. For more information on this restriction, see the following document:
http://www.cisco.com/en/US/docs/interfaces_modules/shared_port_adapters/configuration/7600series/sipspasw.html
- Traffic classes are not supported on Cisco 7600 series routers.
- Prepaid accounting is not supported on Cisco 7600 series routers.
- Per flow accounting using Traffic Classes is not supported on Cisco 7600 series routers.
- ISG Rate limiting via (QU,QD) is not supported on Cisco 7600 series routers.
- Layer 4 Redirect and PBHK are performed on the Centralized Route processor (RP) on Cisco 7600 series routers.
HA Support for DHCP Initiated IP Sessions When ISG Is a DHCP Relay Content
When ISG is configured as a DHCP relay, high availability for DHCP initiated IP sessions is supported only on “unnumbered” interfaces. On numbered interfaces, where the IP address is configured directly on the interface, HA is not supported.
HA Support for ISG Features Includes Change of Authorization but not Per-feature Push
ISG features can be dynamically changed through Change of Authorization (COA). The COA commands are supported for SSO/ISSU. But if a feature is changed, dynamically via per-feature push, HA support is not provided.
VLAN Mobility Is Not Allowed for ISG Sessions
For IP sessions initiated through DHCP, ISG does not allow the users to roam from one VLAN to the other. ISG expects the VLAN to remain the same throughout the user session.
If the user moves from one VLAN to the other, the user needs to reboot the Customer Premise Equipment (laptop or the modem) to initiate a new session.
Limitations and Restrictions in Cisco IOS Release 12.2(33)SRB
This section describes limitations and restrictions in Cisco IOS Release 12.2(33)SRB and later releases.
IP Routing Protocols
Symptom: In rare cases a PE router running BGP may stop announcing BGP updates to subsets of its configured address families.
Conditions: A cisco7600 router running 12.2(33)SRB2 IOS in a L3VPN + L2 VPN converged topology may stop sending BGP updates during initial BGP convergence after enduring a period of interface flaps and linecard OIR.
Workaround: Un-configuring and re-configuring the corresponding neighbor configuration statement will clear the problem.
Multicast VPN
Symptoms: In rare cases, multicast traffic within VRF may not recover after a multicast RP router reload.
Conditions: In a mVPN environment, and on a Cisco7600 PE router running 12.2(33)SRB3 with PIM-SM running in the VRF and mvpn-bidir in the core and with auto-rp, if this PE router encountered a forced SSO switchover while the Multicast RP router is being reloaded, L3VPN multicast traffic on this PE may not recover.
Workaround: Issuing a “clear ip mroute vrf red” command on the PE router will restore the traffic flow.
Symptoms: After a SSO switchover on the PE encap router, mVPN multicast traffic may drop in a VRF
Conditions: In a mVPN environment, and on a Cisco 7600 PE router running 12.2(33)SRB3, and with mvpn-bidir in the core, sparse mode in the VRFs, and with auto-rp, if the encap PE router is reloaded and then followed by a forced SSO switchover, multicast traffic within the VRF may stop forwarding.
Workaround: Unconfiguring and reconfiguring MDT via the following commands will restore the traffic:
Quality of Service
Symptoms: All traffic on an ES-20 line card may get classified as class-default mistakenly .
Conditions: On a Cisco7600 router that is running Cisco IOS Release 12.2(33)SRB3, and with an egress policy-map configured on an ES20 to match multiple class-maps, a policy-map may match all traffic as class-default due to unknown triggers.
L2VPN
Symptoms: Traffic may stop flowing across ONE VC after system reload.
Conditions: This problem is seen on Cisco 7600 router that is running Cisco IOS Release 12.2SRB3 image with ES20 having around 100 EVCs configured with encap dot1q and Xconnect. The problem may be triggered after a router reload or the reset of the ES20 module. To verify if the problem condition is resent, from the ES20 console issue the command sh hw-module subslot slot-no tcam entry vlan port vlan-id1 vlan-id2 etype and if the Ingress policy field is marked as “Deny” as opposed to “Permit” then the condition is present.
Workaround: Reload the ES20 module using command hw-module module module_no reset .
Miscellaneous
Symptoms: Mac-address tables on different DFCs may get out of sync and cause flooding.
Conditions: This problem may occur on a Cisco 7600 that is running Cisco IOS Release 12.2SRB code with distributed forwarding and multi-vc per spoke VPLS configuration on an ES20, SIP400 or SIP600 with mac-sync enabled.
Workaround: Use software based Mac-sync along with Mac-aging timer adjustments using the following guidelines:
–
–
–
Symptoms: The clock source is active immediately after the addition of 'network-clocks' command corresponding to the source, though it is still in OOR actually.
Conditions: On a Cisco 7600 router running 12.2(33)SRB with Dual CEoP Spas, receiving a ref-clock with revertive mode. Once the primary is in OOR, the reference clock switches over to the secondary. If the primary clock source is reconfigured too quickly (removing and adding 'network-clocks select' command), that primary source is reverted back to the reference immediately without waiting for the stabilization.
MPLS
Symptoms: Scalable Ethernet over MPLS configuration on a Cisco 7600 does not work in some configurations. This problem is only for the Scalable EoMPLS case, in which xconnect is configured on SIP400 sub-interfaces, a feature which is documented in the following URL:
http://www.cisco.com/en/US/docs/interfaces_modules/shared_port_adapters/configuration/7600series/76cfgeth.html#wp1172434
Conditions: This symptom is observed on a Cisco 7600 series router with sup720 and IOS 12.2(33)SRA5 and a SIP400 card configured with Scalable EoMPLS.
Workaround: Issue the command 'clear ip route ' when the problem is seen.
The problem is also not seen in the following EoMPLS configurations so changing to the following configurations will avoid the problem:
–
–
L2VPN Pseudowire Redundancy
The following restrictions affect the L2VPN Pseudowire Redundancy feature on the Cisco 7600 series in Cisco IOS Release 12.2(33)SRB:
- IP (routed) Ethernet to VLAN Interworking is not supported.
- Data traffic may switch from the primary pseudowire to the backup pseudowire when the primary attachment circuit at the tail-end goes down. However, when the MPLS switching path for the primary pseudowire goes down, data traffic is not switched from the primary pseudowire to the backup pseudowire.
Limitations and Restrictions in Cisco IOS Release 12.2(33)SRA
This section describes limitations and restrictions in Cisco IOS Release 12.2(33)SRA and later releases.
ADM and AGM Modules
In Cisco IOS Release 12.2(33)SRA and later releases, traffic Anomaly Detection Module (ADM) and Anomaly Guard Module (AGM) modules are supported on the Supervisor Engine 720 but not on the Supervisor Engine 32.
Advanced QinQ Service Mapping
In Cisco IOS Release 12.2(33)SRA and later releases, Advanced QinQ Service Mapping is not supported on the OSM-2+4GE-WAN+ Optical Services Module (OSM).
Cisco IOS CEF
In Cisco IOS Release 12.2(33)SRA and later releases, the Cisco IOS CEF ip load-sharing per-packet , ip cef accounting per-prefix , and ip cef accounting non-recursive commands are not supported on the Cisco 7600 series routers.
Content Switching Modules
In Cisco IOS Release 12.2(33)SRA and later releases, the Content Switching Module (CSM) and Content Switching Module with SSL (CSM-S) are not supported.
IP Services Bundle Image
In the IP services bundle image of Cisco IOS Release 12.2(33)SRA and later releases, you cannot configure both MPLS and IPv6.
IPSec Not Supported by Cisco 7200
Cisco IOS Release 12.2SR does not support IPSec on Cisco 7200 platforms.
L2VPN Interworking
The Cisco 7600 series does not support IP (routed) Ethernet to VLAN Interworking. This restriction affects the L2VPN Interworking feature in Cisco IOS Release 12.2(33)SRA.
Maximum Number of IPsec Tunnels with PKI
In Cisco IOS Release 12.2(33)SRA and later releases, when Public Key Infrastructure (PKI) is configured with the IPsec VPN SPA, a maximum number of 2000 IP security (IPsec) tunnels is supported.
MPLS Aware Netflow
MPLS aware netflow is not supported on Cisco 7600 series routers due to hardware limitation of EARL7 and EARL7.5.
OSM-1CHOC12/T1-SI and QoS Packet Counts
On an OSM-1CHOC12/T1-SI, when Class-Based Weighted Fair Queueing (CBWFQ) or Low Latency Queueing (LLQ) is configured in combination with any feature that requires MSFC or PFC processing, the counters in the output of the show policy-map interface command do not increment. This situation occurs because the MSFC and PFC do not support CBWFQ or LLQ and do not count packets for QoS purposes.
Examples of configurations for which the counters do not increment are the following:
- frame-relay ip tcp header-compression
- frame-relay ip rtp header-compression
- access-list access-list-number permit ip any any log
Note that the log keyword in the access-list command causes packets to be processed by the MSFC or PFC.
Symptoms: On a Cisco 7600 series that is configured with a Supervisor Engine 720 and an OSM-1CHOC12/T1-SI, the output of the show policy-map interface command may display a packet counter of 0 for a serial interface.
This symptom is observed on a Cisco 7600 series that has a Class-Based Weighted Fair Queueing (CBWFQ) or Low Latency Queueing (LLQ) configuration when packets are process-switched in software on the MSFC or PFC instead of being fast-switched, and then the router is reloaded with one of the following saved configurations:
–
access-list 199 permit ip any any log
–
frame-relay ip tcp header-compression
Workaround for the ACL symptom: Remove the log keyword from the access-list command, and then reload the router.
Workaround for the header compression symptom: Enter the no frame-relay ip tcp header-compression command or the no frame-relay ip rtp header-compression command, and then reload the router.
SNMP Version 1 BGP4-MIB Limitations
You may notice incorrect BGP trap OID output when you use the SNMP version 1 BGP4-MIB that is available for download at ftp://ftp.cisco.com/pub/mibs/v1/BGP4-MIB-V1SMI.my . When a router sends BGP traps (notifications) about state changes on an SNMP version 1 monitored BGP peer, the enterprise OID is incorrectly displayed as .1.3.6.1.2.1.15 (bgp) instead of .1.3.6.1.2.1.15.7 (bgpTraps). The problem is not due to any error with Cisco IOS software. This problem occurs because the BGP4-MIB does not follow RFC 1908 rules regarding version 1 and version 2 trap compliance. This MIB is controlled by IANA under the guidance of the IETF, and work is currently in progress by the IETF to replace this MIB with a new version that represents the current state of the BGP protocol. In the meantime, we recommend that you use the SNMP version 2 BGP4-MIB or the CISCO-BGP4-MIB to avoid an incorrect trap OID.
Important Notes
The following sections contain important notes about Cisco IOS Release 12.2SR that can apply to the Cisco 7600 series routers.

Old Behavior: You cannot configure the NetFlow and microflow policy on an interface together.
New Behavior: You can configure per-interface NetFlow and QoS micropolicing on an interface. However, do not configure different flow mask types on an interface. Only a single flow mask type should be configured for the per-interface NetFlow and microflow policy.
Additional Information: http://www.cisco.com/en/US/docs/routers/7600/ios/15S/configuration/guide/nde.html#wp1131072
Old Behavior: The mp-recovery-enable keyword is not available for the hw-module slot command.
New Behavior: The mp-recovery-enable keyword is available.
Additional Information: http://www.cisco.com/en/US/docs/ios-xml/ios/interface/command/ir-f1.html#GUID-642623C0-B2E7-4C48-8163-534377F38142

New Behavior: Taps on the same stream with different port range is accepted.
Additional Information: http://www.cisco.com/en/US/docs/routers/7600/ios/12.2SR/configuration/lawful_intercept/76LIch2.html
- The snmp-server enable traps atm snmp-walk-serial command, which is used to include missing ATM VC SNMP MIB objects of cAal5VccEntry type, is introduced.
Old Behavior: Some ATM VC SNMP MlB objects of cAal5VccEntry type are not displayed when you use the snmpwalk application.
New Behavior: The missing ATM VC SNMP MIB objects are displayed.
Additional Information: http://www.cisco.com/en/US/docs/ios-xml/ios/snmp/command/nm-snmp-cr-book.html
Old Behavior: The switchport commands could be configured on Layer 2 EtherChannel ports, which frequently caused mismatched attributes between the member ports and with LACP, the formation of a secondary aggregator.
New Behavior: The switchport commands cannot be configured on Layer 2 EtherChannel ports. The switchport commands can be configured only on the Layer 2 port-channel interface.
Additional Information: This message is displayed if you attempt to configure the switchport command on an EtherChannel member port:
Configuration is not allowed on Port members. Remove the interface from the Port Channel to modify its config.Cisco IOS Release 12.2(33)SRE6
The following behavior changes are introduced in Cisco IOS Release 12.2(33)SRE6.
- Status of the snmp trap link-status command on the ATM subinterface changes when the device is reloaded.
Old Behavior: The snmp-server enable traps atm subif command enables Simple Network Management Protocol (SNMP) link trap generation on all the ATM subinterfaces. When the device is reloaded SNMP trap generation is enabled on all ATM subinterfaces.
New Behavior: To enable SNMP link trap generation on an ATM subinterface, first configure the snmp-server enable traps atm subif command in global configuration mode and then configure the snmp trap link-status command on the ATM subinterface on which SNMP link trap generation is to be enabled.
Additional Information: http://www.cisco.com/en/US/docs/ios-xml/ios/snmp/command/nm-snmp-cr-s4.html
- Optimization of ACL TCAM entry consumption on the 7600 platforms for Policy Based Routing under certain circumstances.
Old Behavior: When configuring multiple PBR sequences (or a single PBR sequence with multiple ACLs) in which more than one PBR ACL contains DENY entries, the result of the merge is sub-optimal in terms of number of TCAM entries and masks used.
New Behavior: Entering the new platform ipv4 pbr optimize tcam command allows for better optimization in the case described.
http://www.cisco.com/en/US/docs/routers/7600/ios/15S/configuration/guide/layer3.html#wp1027016
Cisco IOS Release 12.2(33)SRE5
The following behavior changes are introduced in Cisco IOS Release 12.2(33)SRE5.
Old Behavior: When the neighbor prefix-length-size command is configured in the L2VPN VPLS address family, if that neighbor has a peer policy or route map that is removed, the neighbor prefix-length-size command setting is also removed.
New Behavior: When the neighbor prefix-length-size command is configured in the L2VPN VPLS address family, the value of that command overrides the value set for the peer-group. If the command is locally configured for the peer, it will not be inherited from the peer-group.
Old Behavior: Prior to the Cisco IOS SRE4 release, the SPA-1xCHOC12/DS0 SPA boots up with the old controller status. If it is not admin down, it starts with no admin down and interfaces comes up as soon as the SPA boots up.
New Behavior: Effective from Cisco IOS Release 15.1(3)S and Cisco IOS Release 12.2(33)SRE05, the SPA-1xCHOC12/DS0 boots up with admin down status and the original SPA status is restored after one second of the SPA bootup. Wait for a second after the log message “SPA_OIR-6-ONLINECARD: SPA (SPA-1XCHOC12/DS0) online in subslot” is displayed, to configure the SPA.
Additional Information: http://www.cisco.com/en/US/docs/interfaces_modules/shared_port_adapters/configuration/7600series/76ovwser.html#wp1058053
Old Behavior: IPv6 IP addresses were blocked when configured under a subinterface.
New Behavior: IPv6 IP addresses are supported when configured under a subinterface using the xconnect command.
Additional Information: http://www.cisco.com/en/US/docs/ios/mpls/command/reference/mp_t1.html#wp1051476
Cisco IOS Release 12.2(33)SRE4
The following behavior changes are introduced in Cisco IOS Release 12.2(33)SRE4.
Old Behavior: By default, both IPv6 and IPv4 capability is exchanged with a BGP peer that has an IPv6 address. When an IPv6 peer is configured, that neighbor is automatically activated under the IPv4 unicast address family.
New Behavior: Starting with new peers being configured, an IPv6 neighbor is no longer automatically activated under the IPv4 address family. You can manually activate the IPv6 neighbor under the IPv4 address family if you want. If you do not want an existing IPv6 peer activated under the IPv4 address family, you can manually deactivate the peer with the no neighbor ipv6-address activate command. Until then, existing configurations that activate an IPv6 neighbor under the IPv4 unicast address family will continue to try to establish a session.

Old Behavior: Destination-only traffic classes cannot be controlled when more than one protocol is operating at the border routers.
New Behavior: Destination-only traffic classes can be controlled when more than one protocol is operating at the border routers using dynamic PBR.
Additional Information: http://www.cisco.com/en/US/docs/ios-xml/ios/pfr/command/pfr-cr-book.html
Old Behavior: Only two members can be added to the port-channel access type subinterface.
New Behavior: Multiple members can be added to the port-channel access type subinterface if the ISG is not configured.

Cisco IOS Release 12.2(33)SRE3
The following behavior changes are introduced in Cisco IOS Release 12.2(33)SRE3.
- SNMP agent returns new error values if the NMS sending the query has a correct SNMP community but does not have a read or a write view.
Old Behavior: In the case of the NMS sending the query, the SNMP agent checks whether the community string is valid. If the community string is valid, then it ensures whether the community has access to a read or write view. This causes a very high CPU load.
New Behavior: In the case of the NMS sending the query having a correct SNMP community but that does not have a read or a write view, the SNMP agent returns the following error values:
–

http://www.cisco.com/en/US/docs/ios/mpls/command/reference/mp_s3.html
http://www.cisco.com/en/US/docs/ios/netmgmt/command/reference/nm_20.html
- Source IP address sent in prune echo messages is now set to the source IP address of the prune echoer.
Old Behavior: The source IP address of prune echo messages is not set to the source IP address of the router that is echoing the prune message (prune echoer). This behavior is not in accordance with RFC 4601 and could potentially cause interoperability issues in certain IPTV deployment scenarios, for example, in VPLS deployments with a mix of Cisco and third-party routers.
New Behavior: The source IP address that is sent in prune echo messages is now set to the source IP address of the prune echoer.
Old Behavior: The following commands display flap-statistics, dampened-paths, and dampening parameters of VRFs under the VPNv4 or VPNv6 address family identifier:
–
–
New Behavior: Because VRFs can have dampening enabled independently of other VRFs and the global VPNv4 and VPNv6 topologies, the following commands display flap-statistics, dampened-paths, and dampening parameters of individual VRFs under that VRF name:
–
–
If dampening is not enabled for a VRF, that is stated under the VRF name.
For more information, see the Cisco IOS IP Routing: BGP Command Reference .
Old behavior: A crash occurs when removing an IPv6 access list that is still applied to a vty.
New behavior: The phrase "Identical restrictions should be set on all the virtual terminal lines because a user can connect to any of them" has been added so users can avoid this problem.
Additional Information: http://www.cisco.com/en/US/docs/ios/ipv6/command/reference/ipv6_05.html
Old Behavior: After a reload of a router, some or all of the BGP address families do not come up. This is because the router is receiving messages from a neighbor that the AFI or SAFI is not supported, and the router does not retry those AFIs. The output of show ip bgp all summary shows the address family in NoNeg or idle state, and it will never leave that state. Typical output looks like:
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd
x.x.x.x 4 1 0 0 1 0 0 never (NoNeg)New Behavior: When the router receives a message that the AFI or SAFI is not supported, the router does not simply drop the rejected AFIs or SAFIs from subsequent OPEN messages. Instead, the router retries the AFI/SAFI within the existing OPEN message retry timing sequence, but with an exponential backoff (stopping at 10 minutes) applied to decisions about whether to include a particular AFI/SAFI in an OPEN message. The timing of OPEN messages is not changed. Successful negotiation of the AFI results in a reset of the backoff sequence for future attempts. Also, when a BGP connection collision occurs with a session in the ESTABLISHED state, BGP sends a CEASE notification on the newly opened connection, and a keepalive message on the old connection. The new connection is closed. If the old session was stale, the keepalive causes it to be closed. The neighbor will retry its OPEN message after receiving the CEASE message and waiting a few seconds.
Old Behavior: The output of the debug ip mfib mrib and the debug ipv6 mfib mrib commands would display EOF messages for a particular multicast group.
New Behavior: EOF messages are no longer displayed in the output of the debug ip mfib mrib and debug ipv6 mfib mrib commands. The detail keyword was added to the debug ip mfib mrib and debug ipv6 mfib mrib commands to display detailed debugging output (including EOF messages). The removal of EOF messages from the display of the debug ip mfib mrib and debug ipv6 mfib mrib commands eases troubleshooting of the MFIB communication with the MRIB.
Old Behavior: ISG reverses the inbound and outbound data values in the ssg-control-info attribute.
New Behavior: The subscriber accounting ssg command allows ISG to use the same format as SSG for the ssg-control-info attribute.
Additional Information: http://www.cisco.com/en/US/docs/ios/isg/command/reference/isg_m1.html
Old Behavior: The total number of active NetFlow flows in a module obtained from an SNMP query is always instantaneous value.
New Behavior: A new keyword, cache , is added to the mls netflow command. When the mls netflow cache command is executed, the command returns a cached value of the total active flow count. The cached value is updated every 30 seconds.
http://www.cisco.com/en/US/docs/ios/netflow/command/reference/nf_02.html#wp1136217
Old Behavior: The MTU and TTL rate limiters were not enabled by default.
New Behavior: The MTU and TTL rate limiters are enabled by default. The default values are 970 and 97 respectively.

Old Behavior: In scaled scenario, SIP200_MP-4-PAUSE messages takes on a lot of logging space and in the process other important logs might get missed.
New Behavior: SIP200_MP-4-PAUSE message to avoid console flooding. Rate limit SIP200_MP-4-PAUSE ensures that one pause message is logged per unique occurrence across the SIP200 reloads and the subsequent occurrences are only statistically accounted.
http://www.cisco.com/en/US/docs/interfaces_modules/shared_port_adapters/configuration/7600series/76tblsip.html.

Cisco IOS Release 12.2(33)SRE2
The following behavior changes are introduced in Cisco IOS Release 12.2(33)SRE2.
Old Behavior: The error throttling command can be enabled only on T1 controllers.
New Behavior: The error throttling command can be enabled on E1 controllers of a channelized E3 port adapter also.
Additional Information: http://www.cisco.com/en/US/docs/ios/interface/command/reference/ir_d1.html#wp1015132
Old Behavior: DHCP server does not send infinite lease time to the clients for which manual bindings are configured.
New Behavior: DHCP server sends infinite lease time to the clients for which manual bindings are configured.
Additional Information: http://www.cisco.com/en/US/docs/ios/ipaddr/configuration/guide/iad_dhcp_svr_cfg_ps10592_TSD_Products_Configuration_Guide_Chapter.html#wp1155880
New Behavior: The optional force keyword was added to the vrf upgrade-cli command. Using this keyword disables the confirmation prompt when performing the upgrade process.
Old Behavior: When the neighbor as-override command is specified to configure that a PE router overrides the autonomous system number (ASN) of a site with the ASN of a provider, it is standard practice to also configure Site of Origin (SoO). SoO, configured on a PE along with neighbor as-override, helps to identify the site of origin for the prefix so that the prefix is not sent back to the source CE from a PE.
New Behavior: An alternative to the SoO feature is using the bgp update-group split as-override command. The bgp update-group split as-override command causes the peers configured with the neighbor as-override command under the same address-family IPv4 VRF, which were previously under one update group, to be removed from that update group and each placed in their own update group.
Additional Information: http://www.cisco.com/en/US/docs/ios/iproute_bgp/command/reference/irg_bgp1.htm
Old Behavior: BGP selects paths which are not the oldest paths for multipaths. This causes BGP to unnecessarily flap from multipaths to non-multipath as a result of route flaps
New Behavior: BGP uses the best-path selection algorithm to find a set of equally good routes. These routes are the potential multipaths. In Cisco IOS Release 12.2(33)SRD and later releases, when there are more equally good multipaths available than the maximum permitted number, then the oldest paths are selected as multipaths.

http://www.cisco.com/en/US/docs/ios/iproute_bgp/configuration/guide/irg_overview.html
Old Behavior: When a connected route is automatically summarized by the auto-summary (BGP) command, the route is not deleted from the BGP routing table if the interface assigned that address is shut down.
New Behavior: When a connected route is automatically summarized by the auto-summary (BGP) command, the route is properly deleted from the BGP routing table if the interface assigned that address is shut down.
For more information, see the auto-summary (BGP) command: http://www.cisco.com/en/US/docs/ios/iproute_bgp/command/reference/irg_bgp1.html
Old Behavior: Command accounting and command authorization that include a 4-byte ASN number are sent in the same format that is used on the command line interface.
New Behavior: Command accounting and command authorization that include a 4-byte ASN number are sent in the asplain notation irrespective of the format that is used on the command line interface.

http://www.cisco.com/en/US/docs/ios/ipv6/command/reference/ipv6_11.html
Old Behavior: On routed interfaces, when mls qos is enabled, ES+ mark the packet as “trust dscp” even when ingress marking of CoS is configured (“set cos 0-7 ”) in the policy map. Because of this, CoS value always propagated from dscp/prec (by EARL).
New Behavior: With the new behavior, for routed interfaces, ES+ mark the packet as “trust cos” when ingress marking of COS is configured. As the result of this, cos value configured using “set cos” will be preserved in the outgoing packet and will not be rewritten by EARL.
Impact to customer: The ES+ line card marks a packet as trust cos when ingress marking for CoS is configured for a routed interface. Hence, the CoS value configured using the set cos value command is retained on the outgoing packet. This cos value is not overwritten by EARL or derived from dscp.
Additional information: http://www.cisco.com/en/US/docs/routers/7600/install_config/ES40_config_guide/es40_chap7.html#wp1346147
Old Behavior: MIB uses the same diag code as BFD internal. However, the MIB definition has values starting at offset 1, while BFD internal (and ietf spec) starts at offset 0. This means all diag codes for down are off by 1.
New Behavior: BFD MIB: bfdSessDiag value for session down traps corrected and updated in the document.
Additional Information: https://www.cisco.com/en/US/docs/ios/iproute_bfd/configuration/guide/irb_bfd_mib.html
Old Behavior: The maximum MTU size that can be configured on POS interfaces is 117994.

Old Behavior: No note was present in the guide saying that the system will not retain the configuration of the old interface.
New Behavior: Added a note in the SIP/SPA Configuration Guide saying “If you move the SPA (SPA-8XTE1/SPA-4xCT3/DS0/SPA-2xCT3/DS0/SPA-1xCHSTM1/OC3) from one LC to another type of LC in the same bay and same slot, the system will not retain the configuration of the old interface”.

Cisco IOS Release 12.2(33)SRE1
The following behavior changes are introduced in Cisco IOS Release 12.2(33)SRE1.
- The syslog error message for multicast Call Admission Control (CAC) limits now shows information about both limits and interfaces.
Old Behavior: When the multicast CAC limit is configured at both the main and subinterface, the syslog error message shown when the multicast CAC limit was reached did not mention the exact interface limit that denied the OLE addition.
New Behavior: The syslog error message is updated with the information about the limit and the interface on which it was denied. See the following example:
*Feb 19 10:36:11.514 PST: %IPMCAST_LIB-4-IPMCAST_LIMIT: Adding Outgoing interface 'Ethernet0/0.2' denied for (*,FF03::1:1:6) due to limit (4) in Ethernet0/0
-Process= "PIM IPv6", ipl= 0, pid= 143.http://www.cisco.com/en/US/docs/ios/12_2sb/system/messages/sys_msg_book.html
Old Behavior: The dialer pool-member command was available on Cisco IOS Release 12.2(33)SRB and later releases.
New Behavior: The dialer pool-member command is not supported on Cisco IOS 12.2SR releases.
http://www.cisco.com/en/US/docs/ios/dial/command/reference/dia_d1.html#wp1033489
New Behavior: Use the BRE+APS feature to configure two VCs for the same VLAN, provided their parent interfaces too belong to the same Automatic Protection Switching (APS) group.
Old Behavior: BRE does not work on APS protected ATM interfaces. You should configure “bre-connect” on both ATM interfaces with the same vlan. Currently, software allows only one bre-connect per vlan. This restriction needs to be removed for making BRE work with APS.
http://www.cisco.com/en/US/docs/routers/7600/ios/12.2SR/configuration/guide/vlans.html and http://www.cisco.com/en/US/docs/routers/7600/ios/12.2SR/configuration/guide/vlans.html

New Behavior: Unicast and broadcast traffic from Private host isolated ports are sent over VPLS enabled interfaces.
Private Host feature can be enabled with VPLS enabled interfaces acting as Private host promiscuous ports.
New commands and key words included:
private-hosts mac-list mac-list-name mac address
private-hosts vlan-list vlan-id
private-hosts promiscuous mac-list-name [ vlan-list vlan-id ]
Old Behavior: 8 DWDM SFPs DWDM-SFP-3346, DWDM-SFP-3739, DWDM-SFP-4134, DWDM-SFP-4532, DWDM-SFP-4931, DWDM-SFP-5332, DWDM-SFP-5736, DWDM-SFP-6141 were not supported on ES20/SIP-400/SIP-600.
New Behavior: Support the additional 8 DWDM SFPs on ES20/SIP-400/SIP-600.
http://www.cisco.com/en/US/docs/routers/7600/Hardware/12.2SR_supported_hw/7600_hwd.html
New Behavior: Current operational state of the peer port is not “error disabled”and is in “Advertisment” state.
Old Behavior: When you configure SPAN and UDLD combinations on a port where the interface is a SPAN destination port, the current operational state of the peer is disabled as the peer disables the port.
Additional Information: http://www.cisco.com/en/US/docs/routers/7600/ios/12.2SR/configuration/guide/ude_udlr.html#wp1041358
Updated section: UDE Configuration Guidelines
No commands, keywords, and arguments that have been changed.
Changes to default behavior if appropriate: Peer port is no longer in error disabled state but is in Advertisement state.
Old Behavior: There is no limit on the number of L4 redirects.
New Behavior: Maximum number of L4 redirects can be configured with redirect session-limit command.
http://www.cisco.com/en/US/docs/ios/isg/configuration/guide/isg_l4_redirect.html and http://www.cisco.com/en/US/docs/ios/isg/command/reference/isg_m1.html
New Behavior: A new CLI enables or disables the trust state over the internal recirculate path. The CLI is described as: “[no] mls qos recirc untrust [slot ]”.
For complete syntax and usage information for the command mls qos recirc untrust , see the Cisco QoS command reference at this URL:
http://www.cisco.com/en/US/docs/ios/qos/command/reference/qos_book.html
Old Behavior: The bit “CR_UNTRUST” on DE_NOT_DE_MISC_CNTRL is currently enabled by default on the Earl, when it boots up in PFC3C mode and currently does not have any CLI to control or modify its state.
http://www.cisco.com/en/US/docs/routers/7600/ios/12.2SR/configuration/guide/swcg.html and http://www.cisco.com/en/US/docs/routers/7600/Hardware/Hardware_Guides/Supervisor_Engine_and_Route_Switch_Processor_Guide/76-sup-rsp.html
Updated section: QoS on the RSP720-10GE
Commands, keywords, and arguments have been changed. A new command mls qos recirc untrust is introduced
Old Behavior: Policy map with cos based wred is rejected on main interface of ES+ line card.
New Behavior: Policy map with cos based wred is accepted on the main interface of ES+ line card.
All the dot1q traffic passing through this main interface is subjected to this wred based on their respective cos markings.
Impact to customer: For EVC, subinterfaces, and Layer 3 main interface the WRED support is now dscp-based, precedence-based, and cos-based.

Old Behavior: The bfd-ctrl , bfd-echo , glbp , and vrrp keywords are not available with the mls qos protocol command.
New Behavior: These four keywords are now available with this command.
http://www.cisco.com/en/US/docs/ios/qos/command/reference/qos_m2.html
Old Behavior: Cisco IOS software releases process NTP mode 7 packets.
New Behavior: Cisco IOS software releases where CSCtd75033 is resolved do not process
NTP mode 7 packets, and instead, if debugs for NTP are enabled, display “NTP: Receive: dropping message: Received NTP private mode packet. 7”.
To have Cisco IOS Software process NTP mode 7 packets, enter the ntp allow mode private command (disabled by default).
Cisco IOS Release 12.2(33)SRD6
The following behavior changes are introduced in Cisco IOS Release 12.2(33)SRD6.
Old Behavior: In scaled scenario, SIP200_MP-4-PAUSE messages takes on a lot of logging space, and in the process other important logs might get missed.
New Behavior: SIP200_MP-4-PAUSE message is added to avoid console flooding.
Impact to customer: Rate limit SIP200_MP-4-PAUSE ensures that one pause message is logged per unique occurrence across the SIP200 reloads, and the subsequent occurrences are only statistically accounted.

- Source IP address sent in prune echo messages is now set to the source IP address of the prune echoer.
Old Behavior: The source IP address of prune echo messages is not set to the source IP address of the router that is echoing the prune message (prune echoer). This behavior is not in accordance with RFC 4601 and could potentially cause interoperability issues in certain IPTV deployment scenarios, for example, in VPLS deployments with a mix of Cisco and third-party routers.
New Behavior: The source IP address that is sent in prune echo messages is now set to the source IP address of the prune echoer.
Old Behavior: BGP selects paths which are not the oldest paths for multipaths. This causes BGP to unnecessarily flap from multipaths to non-multipath as a result of route flaps
New Behavior: BGP uses the best-path selection algorithm to find a set of equally good routes. These routes are the potential multipaths. In Cisco IOS Release 12.2(33)SRD and later releases, when there are more equally good multipaths available than the maximum permitted number, then the oldest paths are selected as multipaths.

Old Behavior: On routed interfaces, when mls qos enabled, ES+ mark the packet as “trust dscp” even when ingress marking of COS is configured (set con 0-7 ) in the policy map. Because of this, CoS value always propagated from dscp/prec.
New Behavior: With the new behavior, for routed interfaces, ES+ mark the packet as “trust cos” when ingress marking of CoS is configured. As the result of this, CoS value configured using “set cos” will be preserved in the outgoing packet and will not be rewritten.
Impact to customer: The ES+ line card marks a packet as trust cos when ingress marking for CoS is configured for a routed interface. Hence, the CoS value configured using the set cos value command is retained on the outgoing packet. This CoS value is not overwritten or derived from DSCP.

The following behavior changes are introduced in Cisco IOS Release 12.2(33)SRD4.
New Behavior: Added the domain command under - aaa dynamic author context which configures username domain options for the RADIUS application.
The latest command is available at:
http://www.cisco.com/en/US/docs/ios/security/command/reference/sec_d2.html
Old Behavior: More specific routes are advertised and withdrawn later, even if aggregate-address summary-only is configured. The BGP table shows the specific prefixes as suppressed.
New Behavior: The bgp aggregate-timer command now accepts the value of 0 (zero), which disables the aggregate timer and suppresses the routes immediately.
Old Behavior: When the neighbor as-override command is specified to configure that a PE router overrides the autonomous system number (ASN) of a site with the ASN of a provider, it is standard practice to also configure Site of Origin (SoO). SoO, configured on a PE along with neighbor as-override, helps to identify the site of origin for the prefix so that the prefix is not sent back to the source CE from a PE.
New Behavior: An alternative to the SoO feature is using the bgp update-group split as- override command. The bgp update-group split as-override command causes the peers configured with the neighbor as-override command under the same address-family IPv4 VRF, which were previously under one update group, to be removed from that update group and each placed in their own update group.
Additional Information: http://www.cisco.com/en/US/docs/ios/iproute_bgp/command/reference/irg_bgp1.html
- Old Behavior: BRE does not work on APS protected ATM interfaces. You should configure “bre-connect” on both ATM interfaces with the same vlan. Currently, software allows only one bre-connect per vlan. This restriction needs to be removed for making BRE work with APS.
New Behavior: Use the BRE+APS feature to configure two VCs for the same VLAN, provided their parent interfaces too belong to the same Automatic Protection Switching (APS) group.
Additional Information: http://www.cisco.com/en/US/docs/routers/7600/ios/12.2SR/configuration/guide/vlans.html
- In the earlier design (up to SRD3) subinterfaces numbered 1-300, support high bandwidth (> OC3) operation with QoS configured. Even if only say single subinterface is configured but with subinterface number > 300, then there is a chance that packets may be dropped if traffic rate exceeds OC3 and QoS is configured under the subinterface, due to QoS lock failures. The probability of packet drops, due to QoS lock failures is higher if the pps rate for the subinterface is high (pps cutoff not available) This happens because only subinterface numbered 1-300 are allocated QoS statistics in SRAM, any other subinterface is allocated QoS statistics in DRAM which is considerably slower.
With this DDTS, there is no limitation w.r.t subinterface number used. But, there is still a limit on the total number of subinterfaces (300) per physical port which can have QoS statistics in SRAM. So, with this change, if only g2/0/0.700 to g2/0/0.999 subinterfaces are configured under g2/0/0, then all the subinterfaces will have QoS statistics in SRAM, and there is no bandwidth limitation for these subinterfaces.
Look for following in line card output for interfaces with QoS configuration, below output will indicate if subinterface QoS statistics are maintained in SRAM or DRAM:
SIP-400-2#sh platform np qos class tables all | include SRAM
SIP-400-2#sh platform np qos class tables all | include DRAM
Old Behavior: Limits are not enforced on the number of subscriber sessions.
New Behavior: Number of subscriber sessions is restricted per ES+ line card, SIP400 line card, and per chassis.

- Old Behavior: When you configure SPAN and UDLD combinations on a port where the interface is a SPAN destination port, the current operational state of the peer is disabled as the peer disables the port.
New Behavior: Current operational state of the peer port is not “error disabled” and is in “Advertisement” state.

Cisco IOS Release 12.2(33)SRD3
The following behavior changes are introduced in Cisco IOS Release 12.2(33)SRD3.
Old Behavior: No cache was maintained for CISCO-FLASH-MIB
New Behavior: A new command snmp mib flash cache has been added to start a process that constructs and maintains a cache.

- Change for networks using redistribution from BGP into OSPF in VRF tables, either in MPLS VPN or VRF-lite environments, where redistribution happens on more than one router and the metric of the redistributed route is being used to choose the preferred exit point.
Old Behavior: If BGP is redistributed into OSPF and no route-map or default redistribution metric is specified, the OSPF route is assigned either a metric of 1 if redistribution happens in the global routing table or the metric of the BGP route if redistribution happens in a VRF.
New Behavior: A redistributed OSPF route inherits the BGP metric only if the OSPF route was received via MPLS VPN and contains extended attributes propagating the OSPF metric. In all other cases, the OSPF route receives a metric of 1, including the case of MPLS-VPN routes not carrying an OSPF metric in extended attributes.
Additional Information: http://www.cisco.com/en/US/docs/ios/mpls/configuration/guide/mp_cfg_layer3_vpn_ps6922_TSD_Products_Configuration_Guide_Chapter.html
Old Behavior: Packets dropped by the IP access control lists (ACLs), filters, ISG policing, and prepaid volume features were counted.
New Behavior: Starting with Cisco IOS Release 12.2(33)SRD3, ISG accounting does not count, and subscribers are not billed for, packets dropped by these features.
Additional information: http://www.cisco.com/en/US/docs/ios/isg/configuration/guide/cfg_isg_acctng.html
Old Behavior: Call-home is not VPN Routing/Forwarding (VRF) aware for email messages.
New Behavior: A new CLI command is introduced to enable the VRF support for call-home. Call-home can use the configured interface to send an email message.
Call-home can use the VRF infrastructure to route email messages. If a VRF is not specified in call-home configuration, call-home will use the global routing table to send email messages. If a VRF is specified in call-home config, call-home will only try to use the specified vrf table to send email messages.
Note that call-home HTTPS messages can be sent over a specified source interface on the VRF only by ip http client source-interface command, not depending on this new VRF command under call-home config mode.

Old Behavior: Unicast and broadcast traffic from Private host isolated ports were not sent over VPLS enabled interfaces.
New Behavior: Unicast and broadcast traffic from Private host isolated ports are sent over VPLS enabled interfaces. Private Host feature can be enabled with VPLS enabled interfaces acting as Private host promiscuous ports.
Old Behavior: If SAMI card was running a singleip application, it was not possible to execute rcal commands on TP/TCOPs from SUP through execute-on command.
New Behavior: Executing execute rcal commands on TP/TCOPs is now enabled by providing the command:
execute-on (slot)(control_proc) execute-on (traffic_proc | all) LINE

Old Behavior: The handling of IPv6 packets with hop-by-hop extension header was such that EARL treated them as layer 2 packets and punted all of them to the Routing Processor.
L3 ACLs could not be applied to these packets. A large number of these packets may cause a DoS attack. The requirement is to rate-limit these packets on the SIP-200 line card.
New Behavior: Rate-limiting IPv6 packets with Hop-By-Hop extension headers is supported on SIP-200.

CEoP SPA and APS
When a pseudowire is configured on an interface of a Circuit Emulation over Packet (CEoP) SPA, Automatic Protection Switching (APS) for the interface is useful only in conjunction with pseudowire redundancy.
CEoP SPA and ATMoMPLS
When ATM over MPLS (ATMoMPLS) is configured on a Circuit Emulation over Packet (CEoP) SPA, you cannot connect an ATM network to an OC-3 link nor can you connect an OC-12 network to a T1 link. In order for AToM tunnels that are configured for AAL0 encapsulation or VP mode to function over non-symmetric links, shape the VC or VP to a rate that can be carried by interfaces at both ends by configuring CBR, UBR, or UBR+.
CEoP SPA and Clock Recovery Configuration Guidelines

Detection Mechanism for the MPLS Traffic Engineering (TE)—Fast Reroute (FRR) Node Protection, with RSVP Hellos Support Feature
When the detection mechanism for the MPLS Traffic Engineering (TE)—Fast Reroute (FRR) Node Protection, with RSVP Hellos Support feature is configured with a refresh interval and missed refresh limit that are too short, a neighbor may be declared down while the neighbor is actually up, and a warning message may be generated. To prevent this situation, configure the refresh interval and missed refresh limit in the following ways:
- Ensure that the interval-value argument in the ip rsvp signalling hello refresh interval interval-value command is 200 milliseconds or longer.
- Ensure that the msg-countip argument in the rsvp signalling hello [ fast-reroute ] refresh misses msg-count command has a value of 4 or more.
The detection interval for the detection mechanism should be at least 800 milliseconds (that is, 200 milliseconds of the interval-value argument multiplied by the value 4 of the msg-countip argument) or longer.
ip routing protocol purge interface Command
As of Cisco IOS Release 12.2(33)SRA, you can use the ip routing protocol purge interface command in global configuration mode to enable routing protocols to purge their routes when an interface goes down in the global configuration mode. To disable this function, use the no form of this command.
For detailed information about this command, see the “IP Routing Protocol-Independent Commands” section of the Cisco IOS IP Routing Protocols Command Reference, Release 12.2 SR :
