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]
Defaults — Critical.
Access — Enabled.
History —Introduced in MSS Version 3.2.
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. 3Com 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.
Examples — The following command restores system-critical files on a 
switch, from archive sysa_bak.
