File Management Commands 557

restore

Unzips a system archive created by the backup command and copies the files from the archive onto the switch.

Syntax restore system [tftp:/ip-addr/]filename[all critical] [force]

[tftp:/ip-addr/]filename	Name of the archive file to load. The archive can be
	located in the switch’s nonvolatile storage or on a TFTP
	server.
all	Restores system files and the user files from the archive.
critical	Restores system files only, including the configuration file
	used when booting, and certificate files.
force	Replaces files on the switch with those in the archive, even
	if the switch is not the same as the one from which the
	archive was created.
	CAUTION! Do not use this option unless advised to do so
	by Nortel TAC. If you restore one switch’s system files
	onto another switch, you must generate new key pairs and
	certificates on the switch.
Defaults The default is critical.
Access Enabled.

Usage If a file in the archive has a counterpart on the switch, the archive version of the file replaces the file on the switch. The restore command does not delete files that do not have counterparts in the archive. For example, the command does not completely replace the user files area. Instead, files in the archive are added to the user files area. A file in the user area is replaced only if the archive contains a file with the same name.

Note. If the archive’s files cannot fit on the switch, the restore operation fails. Nortel recommends deleting unneeded image files before creating or restoring an archive.

The backup command stores the MAC address of the switch in the archive. By default, the restore command works only if the MAC address in the archive matches the MAC address of the switch where the restore command is entered. The force option overrides this restriction and allows you to unpack one switch’s archive onto another switch.

Caution! Do not use the force option unless you are certain you want to replace the switch’s files with files from another switch. If you restore one switch’s system files onto another switch, you must generate new key pairs and certificates on the switch.
