Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
CSCsm57494
Symptoms: BGP update is not sent after reloading opposite router or resetting module. Sometimes
a BGP VPNv4 label mismatch also occurs between the routers because BGP update is not received.
Conditions: - This problem may occur once or twice out of 20 attempts. - This problem is apt to
occur when MPLS-TE tunnel is enabled. - This problem may occur when entering either reload
command, hw-module module X reset command or the clear ip /jointfilesconvert/422273/bgp X.X.X.X command on the
opposite router.
Workaround: There is no workaround.
CSCsm58240
Symptoms: Traceback "%LSD-2-INVALID_VAR: app is not owner of label" may be seen while
removing router Border Gateway Protocol (BGP) configuration.
Conditions: Occurs in SSO mode when there are 1000s of routes in BGP table. If we try to remove
router BGP configuration traceback is seen. There is no issue with forwarding of packets due to this.
Workaround: Instead of removing entire router /jointfilesconvert/422273/bgp config you could remove VPN
routing/forwarding (VRF) address family in a step by step way to avoid this traceback.
CSCsm58612
Symptoms: A Cisco ISG reloads when subscriber sessions have traffic classes.
Conditions: This symptom is observed when 1000 to 24,000 sessions go down and come up.
Workaround: There is no workaround.
CSCsm59499
Symptoms: TOOBIG error messages being displayed on the console.
Conditions: The problem is seen on a Cisco 7600 router running Cisco IOS Release 12.2(33)SRB
image when ES20 linecard is subjected to online insertion and removal (OIR).
Workaround: There is no workaround.
CSCsm60223
Symptoms: Crash may occur with error massage in the log:
%SYS-6-STACKLOW: Stack for process Per-Second Jobs running low Breakpoint exception, CPU
signal 23, PC = 0x42789538
Conditions: Occurs when "mpls pal" and Netflow are configured.
Workaround: There is no workaround.
CSCsm60321
Symptoms: A router may reset due to a bus error when removing the legacy traffic shaping
(traffic-shape rate XXX) from the interface with the presence of traffic.
Conditions: Having both the legacy traffic-shaping (traffic-shape rate XXX) and MQC shaping
(through policy-map) configured on the interface and trying to remove either of them will cause this
issue to occur.
Workaround: Avoid making changes to the traffic-shaping configured on the interface with traffic
crossing the interface.
CSCsm61067
Symptoms: Traffic is not forwarded on VPLS pseudowires.
