Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S
Workaround: There is no workaround.
• CSCed54416
Symptoms: A Cisco 12000 series may reload unexpectedly.
Conditions: This symptom is observed when Multiprotocol Label Switching (MPLS) Fast Reroute
(FRR) is configured.
Workaround: There is no workaround.
• CSCed55962
Symptoms: From a local customer edge (CE) router, you may not be able to reach or ping some
prefixes (subnets) on a remote CE router over an Multiprotocol Label Switching (MPLS) network.
Conditions: This symptom is observed in a cell-based MPLS network.
Workaround: Enter the shutdown command followed by the no shutdown command on the affected
subinterface that is connected to the local CE router. Doing so enables the Border Gateway Protocol
(BGP) to run a scan again and repopulates the subnets in the Tag Forwarding Information Base
(TFIB).
• CSCed56025
Symptoms: A VIP, port adapter, or line card may reset.
Conditions: This symptom is observed on a router that has a scaled AToM configuration.
Workaround: There is no workaround.
• CSCed56092
Symptoms: A standby GRP or PRP may keep resetting.
Conditions: This symptom is observed on a Cisco 12000 series when you change releases from
Cisco IOS Release 12.0(27)S to another release using the hw-module standby reload command
and when the RPR mode is enabled.
Workaround: Enter the reload command.
• CSCed56404
Symptoms: On a Cisco 12000 series with link-bundling (port-channel) configured and the
snmp-server enable traps snmp authentication linkdown linkup coldstart warmstart command
configured, if you configure the port-channel with minimum links that are greater that the actual
links, the port-channel is forced down, and an SNMP linkdown trap is generated. However, if you
correct the configuration so that the port-channel comes up, no linkup trap is generated.
Conditions: This symptom is observed on a Cisco 12000 series router that runs Cisco IOS
Release 12.0(26)S1.
Workaround: There is no workaround.
• CSCed57281
Symptoms: A router may log a CPUHOG message that is caused by the CEF reloader process.
Conditions: This symptom is observed on a Cisco router when a VRF with more than 9000 routes
is added to the configuration.
Workaround: There is no workaround.
• CSCed57625
Symptoms: An access control list (ACL) that has logging enabled may not work on a Fast
Etherchannel (FEC) interface.
