Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: The traffic drops when there is a change in path set entries, which can happen when you
perform a shut and no shut the TE tunnel or toggle MPLS traffic-tunnel or use the clear mpls
traffic-eng auto-tunne command.
Workaround: There is no workaround.

Symptoms: High CPU utilization occurs on the new active supervisor after a stateful switchover
(SSO).
Conditions: Occurs when large numbers of logical interfaces (such as port-channel sub-interfaces or
interface VLANs) are configured and earl policing policies applied (uflow policing or aggregate
policing) on all the logical interfaces. The CPU utilization on the active supervisor aggravates on
each switchover.
Workaround: There is no workaround.

Symptoms: A router configured with BGP may generate IPRT-3-NDB_STATE_ERROR log
messages. An additional symptom when /jointfilesconvert/422273/bgp suppress-inactive is configured is that the router CPU
usage may get close to 100%.
Conditions: When both BGP and an IGP are advertising the same prefix, the error condition may
occur. When in addition /jointfilesconvert/422273/bgp suppress-inactive is configured high CPU usage by BGP may be seen.
Workaround: Removing the /jointfilesconvert/422273/bgp suppress-inactive configuration should eliminate the high CPU
problem. Removing either the BGP or IGP conflicting routes from the system should clear both
symptoms.
• CSCsx07181
Symptoms: Router crashes on trying to ping packet over SONET (POS) interface on CHOC12 SPA.
Conditions: The issue was seen on an internal build based on Cisco IOS Release 12.2(33)SRD. The
problem does not occur in the released version of Cisco IOS Release 12.2(33)SRD, but this fix is
required to correct an underlying programming error.
Workaround: There is no workaround.
• CSCsx07317
Symptoms: Static NAT translations can fail after a reload or crash.
Conditions: The trigger seems to be a high number of static translations (~100 translations). Once
the router is rebooted for any reason, the translations will fail.
Workaround: Remove and reapply static translations in the configuration.
• CSCsx08294
Symptoms: A Cisco 6500 running Cisco IOS Release 12.2(33)SXH may encounter a bus error due
to OSPF processes.
Conditions: Occurs when the device is configured for Open Shortest Path First (OSPF).
Workaround: There is no workaround.
• CSCsx09353
Symptoms: Switched Port Analyzer (SPAN) is not capturing traffic in both directions. It only
captures traffic in one direction.
Conditions: Occurs when running Cisco IOS Release 12.2(33)SRC or later and with a ES-20 card.
Workaround: Use another method of packet capture if possible. See VACL capture for details.
Removing the SPAN configuration and reapplying it also helps in getting the feature working.
