Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: In cases where a distance vector protocol is being used (e.g. RIP) and the route goes
into holddown state and then comes out of holddown before the flushtimer has expired, the traceback
described above may occur.
Workaround: The route can be restored by doing:
clear ip route 192.168.116.152
• CSCsm06769
Symptoms: Cisco 7600 configured with service instance under the port-channel interface and
channel-group <port-channel-number> mode on under the physical member, can experience a router
crash if the member is unbundled via issuance of no channel-group <port-channel-number>
mode on.
Conditions: Occurs when port-channel with service instances, and at least one member port are
unbundled using by removal of channel-group command.
Workaround: There is no workaround.
• CSCsm08000
Symptoms: A bridge-domain EVC is configured under port-channel interface. The EVC is in
shutdown state, but the traffic still passes through the EVC.
Conditions: This condition is hit when router boots up with the configuration where a bridge-domain
EVC under port-channel is shutdown.
Workaround: Toggle the admin state of the EVC by performing a shut/no shut under the service
instance.
• CSCsm09338
Symptoms: The following tracebacks are sometimes seen on a switchover of a Cisco 7600 router:
*Feb 1 19:46:32.132 buc: %C6K_PROCMIB-DFC7-3-IPC_PORTOPEN_FAIL: Failed to open port
while connecting to process statistics: error code = no such port
Conditions: Occurs when at least one LAN line card is present in the chassis.
Workaround: There is no workaround.
• CSCsm09618
Symptoms: When performing an ISSU upgrade between the Cisco IOS Release 12.2SRB and Cisco
IOS Release 12.2SRC images, the SIP-400 and ES20 line cards may fail to come online.
Conditions: The problem occurs when issu runversion is run on the active supervisor after issue
loadversion has completed. Some line cards may fail to come online after the new supervisor comes
online.
Workaround: When the supervisor reaches terminal state for SSO, the user can configure power
enable module <x> to re-enable the linecard.
• CSCsm09927
Symptoms: Interface flaps continuously after running atlas BERT.
Conditions: During atlas BERT another interface with lower anyphy number should be deleted.
Workaround: Reload the shared port adapter (SPA).
• CSCsm10103
Symptoms: Attempting to modify queue parameters on a policy map under a port channel interface
may result in changes to the primary member links only. The secondary member links retain the
original values.
