Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
CSCsx20523
Symptoms: Service-policy is not removed from gigabit interface.
Conditions: Occurs after you configure a gigabit interface as a switchport and then attach/detach a
service-policy.
Workaround: In order to remove the service policy configuration, go into the mode where the policy
was first configured and then unconfigure it.
CSCsx20566
Symptoms: Traffic through SIP400 stops or SIP400 displays minor error in show mod output.
Conditions: Seen sometimes on doing RPR+ switchover in a chassis that supports hot fabric
synchronization.
Workaround: Reset the line card.
CSCsx21231
Symptoms: SPA-24CHT1-CE-ATM will remain out of service on a SIP-400 because of a missing
API.
Conditions: This issue will be seen during boot up on a Cisco 7600 router with
SPA-24CHT1-CE-ATM and SIP-400.
Workaround: There is no workaround.
CSCsx21482
Symptoms: The following commands executed from the console result in a device reload: write,
copy running-config startup-config or show run.
Conditions: The symptom is observed when a large number of interfaces (200+) have been
configured for RIPv6 and are active. Interfaces which are down will not contribute to the problem.
Workaround: There is no workaround.
CSCsx21606
Symptoms: On a Cisco 10000 series router that is running Cisco IOS Release 12.2(28)SB11, the
serial interface becomes stuck in an up/down state and the multilink interface in a down/down state.
The debugs indicate:
Se7/0/0.10/17:1 PPP: Missed a Link-Up transition, starting PPP Se7/0/0.10/17:1 PPP: Updating
buffered PPP packet Se7/0/0.10/17:1 PPP: Starting timer for fast-start Se7/0/0.10/17:1 PPP: Handle
allocation failure
Conditions: The symptom is observed when new T1s are added to the router. The triggers are an SSO
configuration and when the router runs for a long time. The new T1s cause a lot of flapping of links.
Workaround: Reload the router or perform a PRE failover on the Cisco 10000 series router.
CSCsx22512
Symptoms: After clearing the DHCP snooping bindings, renewing from the database and reloading
the line card, snooping bindings are lost.
Conditions: Occurs when DHCP snooping is configured to store bindings in the database on the
flash disk.
Workaround: There is no workaround.
CSCsx23566
Symptoms: All Layer 3 traffic is silently dropped on the ES40 line card after the module is reset.
