CSCdy01077 Bug Details

The following error messages may be displayed on the console port of

a Cisco router or switch:

%TFIB-7-SCANSABORTED: TFIB scan not completing. MAC string updated.

%TFIB-DFC8-7-SCANSABORTED: TFIB scan not completing. MAC string updated. *

The messages may continue to be displayed until the router or switch

is reloaded. The error messages are informational and indicate that an

excessive amount of network or line transitions may cause an excessive number

of Forwarding Information Base (FIB) scans. Processes that are attempting to

converge on the network may cause the Route Processor (RP) and/or the Switch

Processor (SP) CPU utilization to occasionally reach 100 percent.

Workaround: There is no workaround.
