BACKING UP AND RESTORING SWITCH 
CONFIGURATIONS

Once your SmartCell ZX-250 ATM switch is up and running (or you have made extensive changes to the 
configuration), you should back up the switch configuration. If the flash RAM gets formatted or corrupted, you can 
restore the switch configuration from the backup file.

2p›F

The 

 command backs up only the configuration files. It does not back up 

an image of the switch’s operating software.

To perform a back up or restore, you must have TFTP server software running on an end station that’s reachable by the 
SmartCell ZX-250. The 

 command copies the configuration files on the switch to a directory specified by the 

TFTP server software. Often, this directory is /tftpboot; however, it may be different with your TFTP server software. 
Backup file names can be anything. Both the target backup directory and its file must exist and have appropriate 
read/write permissions for the backup to complete successfully.

The 

 command prompts you for the IP address of the TFTP server end station, the backup path, and the name 

of the file within which you are saving the configuration. For example, if the IP address of the TFTP server end station 
is 90.1.1.100, and you want to save the switch configuration in the file named config-1 under the directory /back_dir, 
enter the following:

SmartCell ZX# backup switch

ServerIP() : 90.1.1.100

Path() : /back_dir/config-1
