Recover your switch configuration
If the configuration file on your switch is altered or corrupted, you

Troubleshoot the Procedure
This section provides information about common problems that you may

SMB
Technical Assistance Center (SMB TAC) for assistance.
Problem
|
Cause(s) and Suggested Solution(s)
|
You are unable to connect to the switch with
CNA.

Make sure you type the correct IP address of the switch in
the Connect window.
-
Ensure that the IP address of your PC matches the IP address

You receive an error message that configuration Back up
failed.
|
Cisco Network Assistant uses an embedded TFTP server for back
up. The back up can possibly fail, if you use TFTP server in another instance
of Network Assistant or if a third party TFTP server is already running in your
PC.
If you are connected to the switch, close the TFTP server and
repeat the Back up procedure.
If you are still unable to complete the procedure successfully,
contact the
SMB
TAC for assistance.
