Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• In an MPLS-VPN topology where a Catalyst 6500 series switch or Cisco7600 Internet Router is
functioning as a provider router, the following informational error messages might be displayed:
*Jul 1 18:25:23.709: %TFIB-7-SCANSABORTED: TFIB scan not completing. MAC string
updated.
*Jul 1 18:25:25.285: %TFIB-DFC8-7-SCANSABORTED: TFIB scan not completing. MAC string
updated.
*Jul 1 18:26:24.049: %TFIB-7-SCANSABORTED: TFIB scan not completing. MAC string
updated.
*Jul 1 18:27:23.945: %TFIB-7-SCANSABORTED: TFIB scan not completing. MAC string
updated.
*Jul 1 18:27:24.949: %TFIB-SP-7-SCANSABORTED: TFIB scan not completing. MAC string
updated.
These messages continue to be displayed until you reload the system. After a steady traffic rate is
reached, the error messages should stop. While these messages are displayed, route processor and
switch processor CPU utilization also increases to 100 percent because a background process is
attempting to converge the network. (CSCdy21998)
Note CSCdy21998 is not seen in later releases.
• After an OIR of a FlexWAN or OSM, the following error message might be displayed if the route
processor is busy and CPU utilization is more than 60 percent:
%FIB-3-FIBDISABLE: Fatal error, slot/cpu 10/1: No window message, LC to RP IPC is
non-operational
When this condition occurs, traffic forwarding stops on the affected module.
Workaround: Reset the affected module one more time, which may resolve the problem.
(CSCdx75137)
Note CSCdx75137 is not seen in later releases.
• If multiple OC-12-ATM OSMs with large configurations are installed in a system, you may not be
able to boot the OC-12-ATM OSMs simultaneously. This problem is resolved in Release 12.1(13)E1.
(CSCdy21621, CSCdy14468)
• In a system with a channelized DS3 OSM installed and more than 10,000 IP routes present, the
following error message may be displayed for the channelized DS3 OSM:
FIB-3-FIBDISABLE: Fatal error, slot/cpu 4/0: no memory
Workaround: Upgrade the memory on the channelized DS3 OSM from 64 MB to 128 MB. This
problem is resolved in Release 12.1(13)E1. (CSCdy19072, CSCdy40632)
• In a system with a large number of Frame Relay subinterfaces configured, some subinterfaces will
not be functional after the system switches over from the active route processor to the redundant
route processor.
Workaround: Enter a shutdown command followed by a no shutdown command on the main
interface. This problem is resolved in Release 12.1(13)E1. (CSCdy26531)
Resolved OSM Caveats in Release 12.1(12c)E5
None.
