File Management Commands 557
Nortel WLAN—Security Switch 2300 Series Command Line Reference
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]
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.
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.
[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.
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.
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.
