Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
• CSCte58749
Symptoms: Some interfaces start flapping upon upgrading to Cisco IOS Release 12.2(33)SRD3.
Conditions: This is a corner case condition. The interface flaps occur under following conditions:
1. The peer connected on the other side of the interface sends a CODEREJ for a valid ECHOREP
sent by a Cisco router.
2. On receiving CODEREJ for ECHOREP, the router terminates the PPP session. The PPP
sessions restart, and the interface flaps.
Workaround: Disable keep-alive on the misbehaving peer router.

Symptoms: On a Cisco 7600 series router that is running Cisco IOS Release 12.2(33)SRD3
equipped with an OSM-CHOC12 line card, if a member link is removed and re-added to a multilink
group during periods of congestion, the multilink interface may not recover its full transmit
bandwidth.
This issue only occurs when “service-policy output” is configured on the multilink interface and
when this service policy contains queuing actions.
This condition may be accompanied by the “show policy-map” interface failing to update packet
counters and offered rate.
Conditions: The symptom is observed on a Cisco 7600 series router that is running Cisco IOS
Release 12.2(33)SRD3 equipped with an OSM-CHOC12 line card aggregating multilink interfaces
using queuing policy-maps.
Workaround: Remove and reapply “service-policy output” from the degraded multilink interface.
• CSCte68259
Symptoms: Random end-to-end traffic failure with an ES+ line card with L2TPv3 termination on
one port which is interfacing with EVC BD remotely.
Conditions: This issue occurs when the ES+ line card is configured with the L2TPv3 feature.
Workaround: There is no workaround.
• CSCte95228
Symptoms: The line card 7600-ES+ on a Cisco 7600 series router may reload due to memory
corruption.
Conditions: One of the conditions is cable pull with scaled configurations. This is seen with VPLS
configuration only so far. This is a rare situation and seen only once.
Workaround: Shut the port on which OIR is done.
• CSCte99481
Symptoms: After SSO if you get drop for around 30 secs having VPLS and 4k HWIBDS.
Further Problem Description: After switchover the process which clears the counters for HWIDBS
take the whole of CPU and not allowing OSPF to work properly. Resulting in the drop of traffic.
• CSCti78408
Symptoms: %SYS-DFC4-3-CPUHOG: Task is running for (128000)msecs, more than (2000)msecs
(4/3),process = console_rpc_server_action.
%SYS-DFC4-2-WATCHDOG: Process aborted on watchdog timeout, process =
console_rpc_server_action.
