Backing Up and Restoring the System 615

Managing The backup command places the boot configuration file into the archive. Configuration (The boot configuration file is the Configured boot configuration in the

Changes display boot command’s output.) If the running configuration contains changes that have not been saved, these changes are not in the boot configuration file and are not archived. To make sure the archive contains the configuration that is currently running on the switch, use the

save config command to save the running configuration to the boot configuration file, before using the backup command.

The restore command replaces the boot configuration on the switch with the one in the archive. The boot configuration includes the configuration filename and the image filename to use after the next switch restart. (These are the Configured boot image and Configured boot configuration files listed in the display boot command’s output.) The restore command does not affect the running image or the running configuration.

If you want to use the configuration in the boot configuration file restored from an archive instead of the configuration currently running on the switch, use the load config command to load the boot configuration file, or restart the switch. If instead, you want to replace the configuration restored from the archive with the running configuration, use the save config command to save the running configuration to the boot configuration file.

The next time the switch is restarted after the restore command is used, the switch uses the boot configuration filename that was in use when the archive was created. If you change the boot configuration filename after creating the archive, the new name is not used when the switch is restarted. To use the new configuration, use the save config filename command, where filename is the name of the boot configuration file restored from the archive, before you restart the switch. If you have already restarted the switch, use the load config filename command to load the new configuration, then use the save config filename command.

Backup and Restore The following command creates an archive of the system-critical files and Examples copies the archive directly to a TFTP server. The filename in this example

includes a TFTP server IP address, so the archive is not stored locally on the switch.
