For more information on configuring the EFP Egress Filtering feature including the associated EFP Egress Filtering commands on the Cisco ASR 9000 Series router, refer to the Egress EFP Filtering on the Cisco ASR 9000 Series Router feature module.
•
In prior releases the Cisco ASR 9000 Series Router acting as a bridge flooded broadcast and unknown unicast traffic to all the forwarding engines on all the line cards.
In Cisco IOS XR Software Release 3.7.2 if a pseudo wire is configured in a bridge domain all broadcast and unknown unicast traffic is flooded to all line cards in the system in order to attain fast convergence. With Cisco IOS XR Software Release 3.7.3 the flood optimization feature changes this default behavior. FGID will get programmed based on the primary paths on which the pseudo wire is going out and traffic will get flooded only to the line cards on which the pseudo wire resides. This mode is called Bandwidth Optimization mode.
But if a Fast ReRoute event occurs when fast convergence is set up it will take a longer time to complete the reroute as more hardware programming such as adding bridge ports etc. needs to be done. So for customers who are sensitive to this increased delay a command called flood mode convergence-optimized is provided in Cisco IOS XR Software Release 3.7.3. Use this flood mode convergence-optimized command to switch back to the convergence optimized mode where traffic gets flooded to all the line cards.
With this flood mode convergence-optimized command users are able to turn on/off the bandwidth optimized mode.
For more information on the flooding disable command and other Layer 2 VPLS commands on the Cisco ASR 9000 Series router, refer to the Multipoint Layer 2 Bridging Services (VPLS) Commands on Cisco ASR 9000 Series Routers section in the Cisco ASR 9000 Series Aggregation Services Router MPLS Command Reference here:
http://www.cisco.com/en/US/docs/routers/asr9000/software/mpls/command/reference/grasr9kvpls.html
•
In Cisco IOS XR software Release 3.7.3 as part of pseudo wire flood optimization, the Layer 3 interface list for a pseudo wire is now based on Virtual Connection labels. By using ECMP Link Bundle hashing, the Layer 3 interface list for a pseudo wire can be condensed to a single Layer 3 interface. This Layer 3 interface (slot and network protocol flood mask) is derived from the ordered array of Layer 3 interface list (masks).
•
Cisco IOS XR software Release 3.7.3 adds support for the Early Fast Discard command. This command was added to process all high priority packets
Command syntax:
(config)# hw-module location <loc> early-fast-discard(config-early-fast-discard)# mode [outer-encap-only | include-inner-encap](config-early-fast-discard)# vlan-cos <0-8> vlan-op [lt | ge]The defaults are 6 and ge (greater than or equal to)(config-early-fast-discard)# ip-prec <0-8> ip-op [lt | ge]The defaults are 6 and ge (greater than or equal to)(config-early-fast-discard)# mpls-exp <0-8> mpls-op [lt | ge]The defaults are 6 and ge (greater than or equal to)(config)# no hw-module location <loc> early-fast-discard•
Cisco IOS XR software Release 3.7.3 adds support for the user to override the Power Management feature in order to configure extra line cards without full power supply redundancy.
This feature allows a card to be forced to power up, regardless of an unprogrammed EEPROM power draw value. As with the ROMMON variable, this feature is intended for temporary use. After the cookie value has been programmed, remove this configuration by repeating the CLI command with the ''no'' option.
Command example:
RP/0/RSP0/CPU0:ios(admin-config)# hw-mod power override location <loc>•
Starting with Cisco IOS XR software Release 3.7.3, mrouter and membership states on the Cisco ASR 9000 Series Router no longer need to be relearned after a port goes down. Once a port goes down, the IGMP Snooping feature immediately removes all group membership states from that port. Once an mrouter port goes down, the IGMP Snooping feature removes the port from the list of mrouter ports and removes that port from the flood set of all multicast routes.
New CLI:
tcn_relearning [cisco | rfc4541 | none]
For more information on the IGMP Snooping feature on the Cisco ASR 9000 Series router, refer to the Implementing Layer 2 Multicast using IGMP Snooping on Cisco ASR 9000 Series Routers section in the Cisco ASR 9000 Series Aggregation Services Router Multicast Configuration Guide here:
•
Cisco IOS XR software Release 3.7.3 improves the Cisco ASR 9000 Series Router VRRP & FRR failover time after a hardware module reload to less than or equal to one second.
•
Layer 2 VPNs can provide pseudo wire resiliency through their routing protocols. When the connectivity between end-to-end PE routers fails, an alternative path to the directed LDP session and the user data takes over. With Cisco IOS XR software Release 3.7.3, the user can fall-back to the preferred path once it has been restored.

Caveats
Caveats describe unexpected behavior in Cisco IOS XR software releases. Severity-1 caveats are the most serious caveats; severity-2 caveats are less serious.
This section lists the caveats for Cisco ASR 9000 Series Router Software Release 3.9.0 and the Cisco ASR 9000 Series platform.
Open Cisco IOS XR Software Caveats
The following caveats apply to the Cisco ASR 9000 Series Router running Release 3.9.0 of the Cisco IOS XR software:
•
Basic Description:
%SECURITY-LOCALD-3-LWA_ADD_FAIL error when Secret is added for a User
Symptoms:
In rare circumstances, when a user tries to configure username and secret, the configuration succeeds, but the following console message is generated, which seems to suggest that the configuration did not succeed:
"% Failed to commit one or more configuration items.
Please issue 'show configuration failed' from this session to view the errors"
Conditions:
No specific trigger is identified. This is an issue that has been observed a handful of times over several months.
Workaround:
No workaround. Although we get the configuration failure message, operation is successful both on disk and as well as in Sysdb. No Operational Impact of this bug to other parts of this system since it is purely a configuration operation failure.
•
Basic Description:
lpts_pa tracebacks after clearing CEF on line cards.
Symptoms:
An error log is printed along with the traceback when a message send to BCDL agent fails.
Conditions:
The BCDL agent has gone down thus the message send is failing. This is a very rare scenario and would not happen under normal circumstances.
Workaround:
Not required, as BCDL will come up eventually.
•
Basic Description:
telnet session does not return the prompt/control after show commands
Symptom:
When terminal length set to zero and the show commands executed for continuous output, the telnet session does not return the command/router prompt and seems to be hanging, however, only last few lines of the show command output is not displayed.
Hitting ENTER key will display one line of output and pressing spacebar will advance one character on the output device. When the next command is entered, previous missing lines are displayed along with command prompt and again last few lines of the new output will not be displayed. In other words, you can type the new commands and they will get executed, but you will not see the typed commands.
Condition:
This behavior is not exclusively related to long outputs, it can occur with shorter outputs as well both from ADMIN plane as well as EXEC plane when 'terminal length 0' is entered for continuous output display. The trigger is timing issue and will manifest itself at different loads/activities
on the router.
Workaround:
Exit the current session and re-login which gives a new tty session. Also 'process restart devc-vty' should clear ALL the sessions
•
Basic Description:
CLI over XML Configuration Fails
Symptom:
CLI over XML configuration request fails.
Conditions:
This happens when
- CLI command lines in XML request exceeds 200 lines or more
AND
- CLI commands are split internally and it happens to be split in middle of sub-mode.
Workaround:
No need to use CLI over XML for config commands that already support XML natively. Split the commands into multiple requests so that command lines of each request are less than 200 lines.
•
Basic Description:
Connected route missing from routing table after an APS flap and RP FO
Symptom:
Connected route missing from the routing table for APS protected interfaces after APS Switchover, immediately followed by an RP Failover.
Conditions:
APS switchover immediately followed by an RP failover.
Workaround:
None. Reload the Line card associated with the connected route.
•
Basic Description:
"show route backup" only shows 50 entries
Symptom:
"show route backup" only lists the first 50 entries.
Workaround:
"show route summary detailed" shows the correct number of backup routes.
•
Basic Description:
SSM does not support static map for groups other than 232.0.0.0/8
Symptom:
IOS XR does not support configurable static SSM-map ranges outside the default IANA range of 232.x.x.x/8. This applies to both IGMP version 2 and version 3 hosts
Conditions:
No specific conditions.
Workaround:
None.
Caveats Specific to the Cisco ASR 9000 Series Router
The following caveats are specific to the Cisco ASR 9000 Series platform:
•
Basic Description:
BGP tracebacks with %ROUTING-BGP-4-RIB_REG_FAIL.
Symptom:
BGP prints out a low-severity ios-msg with traceback indicating failure to register a VRF with RIB. The message looks like the following
%ROUTING-BGP-4-RIB_REG_FAIL : [7] : Failed to register BGP protocol with RIBfor TBL:vpn770 (1/1): 'BGP' detected the 'warning' condition 'Failed callingRIB library' (error code: 0x4ffdd200) : pkg/bin/bgp : (PID=254196) :-Traceback= 4e069a8c 4e069f70 4e06a104 4c22bb30 4c22c010 4c22c1ec 4e05d6444e068020 4e08270c 4c1ff624 4c1f9dd0 4c1faae4 4c1f8bb4 4dd87e68 4e05d29c 4c27b3c4Conditions:
The above ios-msg has been seen on an ASR9K platform with scale L3VPN configuration (2-4K VRF interfaces), after RSP switchover. There is no operational impact on the router. Traffic is not impacted after the ios-msg is seen. All the BGP routes are present in the RIB for the VRF table for which the ios-msg is seen.
Workaround:
This message may be seen as a transient issue with a large VRF scale when the CPU is really busy. A FO is such an event. BGP will print out this msg as a notification when it's call to register a VRF with RIB fails. BGP will continue to try to register the VRF. It is recommended that the VRF should be checked using the show rib vrf < vrf_name > protocols to check whether BGP has registered the VRF and show route vrf < vrf_name > bgp to make sure that all the BGP routes are present in the VRF.
In the very unlikely event that the registration did not go through even after repeated BGP retries, the VRF can be cleared using the following command to reinstall the routes
clear route vrf < vrf_name > afi-all safi-all
•
Basic Description:
Show interface accounting/rate values for MCAST are incorrect
Symptom:
Accessing the show interface < x > accounting or show interface < x > accounting rate command generates output with extremely large and incorrect values for multicast traffic.
Condition:
The 30 seconds periodic timer did not accumulate the IPv4_MCAST counter. This counter when retrieved via on demand CLI will show a huge number as the counter accumulates in the LC. The net effect, 'show interface accounting' CLI display a large counter value, ''show interface accounting rate' CLI display an incorrect accounting rate because the rate is calculated via a sliding window algorithm. At this window, accumulated counts are retrieved hence causes the spike in IPV4_MCAST rate. This symptom is only seen when the on demand CLI is not issued for a period of time.
Workaround:
None
•
Basic Description:
show inventory shows wrong SFP/XFP Info
Symptom:
"sh inventory" command displays "Serial Number, Product id and Description of each Card and port installed on the router. For ports not installed it should not display anything but for 2x10Gig and 20x1 gig port card it is displaying description for those ports, where there is no optic installed.
Conditions:
No optic installed on the port.
Workaround:
None
•
Basic Description:
IPSLA fails on A9K-SIP-700 and ICMP's are all failing over the SIP
Symptom:
If IPSLA is used over a SIP700 based linecard, pings executed from the router prompt will fail over that circuit and ipsla is not operational due to ping timeouts.
Conditions:
Only when IPSLA is running over a SIP based circuit, that is an interface that resides on the SIP700 SPA carrier card (e.g. CHOC12/DS1 circuits/MLP)
Workaround:
Disable IPSLA over SIP700 based circuits
Resolved Cisco IOS XR Software PSIRT-Related Caveats
•
Basic Description:
BGP flaps due to unknown attribute
Symptom:
Cisco IOS XR Software contains a vulnerability in the Border Gateway Protocol (BGP) feature. The vulnerability manifests itself when a BGP peer announces a prefix with a specific, valid but unrecognized transitive attribute. On receipt of this prefix, the Cisco IOS XR device will corrupt the attribute before sending it to the neighboring devices. Neighboring devices that receive this corrupted update may reset the BGP peering session.
Conditions:
Affected devices running Cisco IOS XR Software corrupt the unrecognized attribute before sending to neighboring devices, but neighboring devices may be running operating systems other than Cisco IOS XR Software and may still reset the BGP peering session after receiving the corrupted update. This is per standards defining the operation of BGP.
Workaround:
No workaround. Cisco developed a fix that addresses this vulnerability and will be releasing free software maintenance upgrades (SMUs) progressively starting 28 August 2010.
A Security Advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20100827-bgp.shtml
