Chapter 3 Troubleshooting
Diagnosing Problems
Correcting Module POST Failures
If you install modules WS-X2914-XL or WS-X2922-XL in a Catalyst 2924M XL
or Catalyst 2912MF XL switch, the module fails POST. This failure occurs
because the expansion modules support 2048 MAC addresses and the switch
supports 8192 MAC addresses. To correct the failure, restart the switch with the
module installed. After the restart, the address capacity of the switch is reduced
to 2048 MAC addresses.
Diagnosing Problems
Common switch problems fall into the following categories:
Poor performance
No connectivity
Corrupted software
Table 3-2 describes how to detect and resolve these problems.
