Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: When the MCP-ISG is acting as DHCP Relay Agent or DHCP server, it crashes while
large number of Layer 2-connected sessions are coming up.
Workaround: There is no workaround.
• CSCsu10229
Symptoms: cdpCacheAddress(OID:1.3.6.1.4.1.9.9.23.1.2.1.1.4) MIB is not showing
GLOBAL_UNICAST address.
Conditions: Occurs on a Cisco 7200 router running Cisco IOS Release 12.4(15)T7.
Workaround: There is no workaround.
• CSCsu12040
Symptoms: BGP neighbors that are configured with as-override and send-label (CsC) together may
not work after an interface flap or service reset.
Conditions:
neighbor xxx as-override neighbor xxx send-label
Workaround: Enter the “clear ip /jointfilesconvert/422273/bgp * soft in” command.
Further Problem Description: Peers (neighbors) with a CsC (IPv4+label) BGP configuration with
the as-override option should be separated into different dynamic update groups during the BGP
update generation process. After the CSCef70161 fix in Cisco IOS Release 12.0(32)SY4, this is no
longer the case; this CSCsu12040 fix enhances the CSCef70161 fix to handle the CsC (IPv4+label)
case separately.

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
• CSCsu26315
Symptoms: Traffic may not resume on ATM over MPLS (ATMoMPLS) connections.
Conditions: The symptom is observed when both ATMoMPLS and ATM over LS (ATMoLS)
connections are on same card and a card reset is done.
Workaround: Reload the PXF.
• CSCsu27109
Symptoms: When stateful switchover (SSO) is performed on a Cisco 7600, MPLS label allocation
fails.
Conditions: Issues are seen on Cisco 7600 router. Occurs after performing the SSO. Also seeing
CPU usage above 95% for 10-15 minutes.
Workaround: There is no workaround.
