Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8

OL-10394-05 Rev. R0

Following the removal of the configuration, at least two minutes must elapse so that BGP can

complete its cleanup. When no nets belonging to the VRF remain in the BGP table it should be safe

to delete the VRF without the possibility of hitting this issue.

• CSCsx65705

Symptoms: The router crashes upon executing the no route-map command with a match statement

referencing an already-removed access-list.

Conditions: The symptom is observed when the access-list is not present while executing the no

route-map command.

Workaround: Remove the match statements which are pointing to the access-list before the

access-list is removed.

• CSCsx69555

Symptoms: Unknown prefixes show up in the BGP table when “route-map” is configured on a

neighbor and labels are sent from the other side.

Conditions: The symptom is observed when the command set mpls-label is not given inside the

route-map.

Workaround: Give the command set mpls-label under all the route-maps configured on the

neighbors.

• CSCsx70085

Symptoms: Router watch failed.

Conditions: Issue occurs randomly with a very low probability if you are running an HA system.

Workaround: There is no workaround.

• CSCsx87562

Symptoms: The following error is seen following interface range configuration change:

%SYS-3-TIMERNEG: Cannot start timer (0xXXXXXXXX) with negative offset (- YYYYYYYYYY).

-Process= "<interrupt level>", ipl= 2

Conditions: This symptom is seen with dual supervisors installed and affects these

Cisco Catalyst 4000 releases: 12.2(52)SG/XO, 12.2(50)SG4/5/6, 12.2(53)SG/SG1.

Workaround:

1. Configure the interfaces one by one.

2. Force a switchover “redundancy force-switchover”.

3. Use Cisco IOS Release 12.2(50)SG3 until the fix code is released.

• CSCsy08048

Symptoms: Memory usage increases by about 10MB in processor memory following the creation of

new checkpointing buffer pools. The result is less free memory available for other purposes.

Conditions: This increase is of a fixed size, is seen immediately after boot, and is not

configuration-dependent.

Workaround: This issue should not impact most customers unless they are reaching the very limits

of free memory with their configuration, in which case a reduction in the scale of configuration

would work around the problem but may result in diminished features or scalability.

• CSCsy09743

Symptoms: Multilinks flap after being added to an MLP bundle with a service policy attached to the

interface.
