Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
• CSCsu24087
Symptoms: A router hangs for a couple of minutes, then crashes anytime the clear ip /jointfilesconvert/422273/bgp neighbor
x.x.x in command is issued.
Conditions: This symptom occurs when a router crashes when the clear ip /jointfilesconvert/422273/bgp neighbor x.x.x.x
soft in command is issued when the following commands are configured for that neighbor (without
route-map): 1) neighbor x.x.x.x soft-reconfiguration inbound 2) neighbor x.x.x.x weight 3)
neighbor x.x.x.x filter-list in
If any one of the commands is not configured, then the router will not crash.
Workaround: Configure route-map instead of filter-list for inbound direction. For example:
"neighbor x.x.x.x filter-list 1 in" replace with "neighbor x.x.x.x route-map name in"
where, route-map name permit 10 match as-path 1

Symptoms: Bootup diag test failures observed on 6816 card when multirouters are reloaded. Some
ports were put in error disabled state.
Conditions: Failure trigerred with random multirouters reloads (reload of CE1, PE1, Core1). Brief
router info and config: IOS - 8/25 a76 Dual sup720 7606 6724 connected to remote 6724 (servicing
vlans 2-2000) 6816 connected to remote 6816 (servicing vlans 2001-4000) sip600 (servicing vlans
1-4000 switchport)
Topology:
CE1----PE1----Core-1-----Core-2----PE2----CE2 Affected router is CE1.
Configuration: 4k VLANs, 6816 servicing VLANs 2001-4000 (switchports).
Workaround: Run the failing diag tests on demand.
