Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S8
• CSCsi67310
Symptoms: After RP switchover, all configured WRED thresholds are set to 0 in "sh policy-map int"
command
Conditions: 1. After RP switchover
2. Only on eng5 MPLS trunk
3. Only when the output policy is an unnested policy-map
Workaround: Remove service-policy from the interface and re-attach it or shut/no shut the interface
• CSCsi69492
Symptoms: EoMPLS traffic stops on E4+ on CSC switchover
Conditions: Execute CSC switchover by shutting primary CSC. EoMPLS traffic forwarding stops.
Workaround: To recover, execute mic-reload of E4+ line card.
• CSCsi78221
Symptoms: Engine 3 stucks over minutes (found to be 20 minutes)
Conditions: During BMA recovery
Workaround: There is no workaround.
Further Problem Description: Card resets.
• CSCsi81511
Symptoms: Fails to drain the half packets during error recovery
Conditions: When error recovery is triggered and traffic passes into the Mod48 , during error
recovery , it fails to drain the half packets and fails to initialise the congs.
Workaround: There is no workaround.
• CSCsi96067
Symptoms: Process memory leaks on FRoMPLS router
Condition: - configuring "service-policy output" on the interface, - flowing traffic heavy enough to
be policed by the configuration.
Workaround: There is no workaround at this moment.
Further Problem Description: Flowing about 110 pps traffic, the router crashes with
%SYS-6-STACKLOW on the FR LMI process.
• CSCsj04991
Symptoms: QoS on egress port of E4+ POS is not taking effect if the tunnel headpoint on the same
port as well.
Conditions: The issue happens when we remove the "mpls ip" configuration under the tunnel and
re-add it after a delay.
This does two things.
1.This corrupts and resets the feature processing flag in the ingress adjacency which normally
enables "feature processing in the egress". Since this is reset to 0, the egress is not able to do QoS.
2. The adjacency rewrite info corresponding to the tunnel in the egress gets removed.
Workaround: Remove "mpls ip" from the tunnel interface once and immediately add it back. This
corrects the issue.
