Saving and Restoring Configuration Data

Use the Save/Restore Configuration window to save the current configuration in a file or restore a previously saved configuration.

 

Saving a Configuration

Default configuration settings and most of the settings you configure are stored in a configuration database in the line card's NVRAM.  You can make a copy of the configuration database and back it up on a remote server or host.

Procedure:

Step Action
1 Configure the line card's TCP/IP Host Services to include one IP address for the line card. Refer to Configuring IP Host Services.
2 Enter a name for the file to which you want to save the current line card configuration. Use a file extension of .cfg.

On some systems, you may need to create the file on the remote server or host to which the configuration database is backed up. 

2 Enter the IP address of the TFTP server where you plan to save the configuration file.
3 Select Put as the operation.
4 Click Apply.

Restoring a Configuration

You can restore a configuration database to a line card of the same type from which it was backed up. The restoration process includes verification of a "magic number" that ensures the configuration database is being restored on a line card of the proper type.

You cannot transfer a configuration database using the remote system's version of the TFTP client.

Caution:  Do not power off or reset the line card while restoring the configuration database. NVRAM may become corrupted, requiring you to reinstall the line card's configuration database.

Procedure:

Step Action
1 Enter the name of the file you want to restore to the line card.
2 Enter the IP address for the TFTP server where the configuration file is stored.
3 Select Get as the operation.
4 Click Apply.
