Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S1
• CSCsa77411
Symptoms: When a bandwidth change occurs, a router may crash because of a difficulty with traffic
engineering link management.
Conditions: This symptom is observed on a Cisco router that integrates the fix for caveat
CSCef16096 when the following conditions are present:
–
The router is configured for OSPF and MPLS traffic engineering (TE).
–
The interfaces, OSPF adjacencies, and TE tunnels are flapping.
–
There are more than 300 OSPF interfaces (in any state, including administratively down) in the
OSPF area that is configured for MPLS TE.
You can check the number of interfaces by entering the show ip ospf or show ip ospf interface brief
command. Note that all interfaces that are covered by network statements are included in the
command output, even those that are in the administratively down state.
A list of the affected releases can be found at
http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCef16096. Cisco IOS
software releases that are not listed in the “First Fixed-in Version” field at this location are not
affected.
Workaround: There is no workaround.
• CSCsa80661
Symptoms: The data path on a 3-port Gigabit Ethernet Engine 2 (3GE-GBIC-SC) line card may be
reset because of a corrupted packet that is found in the Tx SOP SRAM. This situation causes packet
loss and the routing protocol sessions to flap.
Conditions: This symptom is observed on a Cisco 12000 series that runs a Cisco IOS software
release that includes the fix for caveat CSCef06121. A list of the affected releases can be found at
http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCef06121. Cisco IOS
software releases that are listed in the “First Fixed-in Version” field at this location are affected.
Workaround: There is no workaround. The symptom causes a disruption of service, but service is
restored.
Further Problem Description: When the symptom occurs, the following messages are generated in
the log:
%RP-3-FABRIC_UNI: Unicast send timed out (1)
