Resetting to the Factory Default Configuration

To reset the WSS switch to its factory default configuration, use the following command:

clear boot config

This command removes the configuration file that the WSS switch searches for after the software is rebooted.

To back up the current configuration file named configuration and reset the WSS switch to the factory default configura- tion, type the following commands:

23x0# copy configuration tftp://10.1.1.1/backupcfg

success: sent 365 bytes in 0.401 seconds [ 910 bytes/sec]

23x0# clear boot config

success: Reset boot config to factory defaults.

23x0# reset system force

...... rebooting ......

The reset system force command reboots the switch. The force option immediately restarts the system and reboots. If you do not use the force option, the command first compares the running configuration to the configuration file. If the files do not match, WSS Software does not restart the WSS switch but instead displays a message advising you to either save the configuration changes or use the force option.

Backing Up and Restoring the System

WSS Software has commands that enable you to easily backup and restore WSS system and user files:

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

The backup command creates an archive in Unix tape archive (tar) format.

The restore command unzips an archive created by the backup command and copies the files from the archive onto the switch. 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.

You can create or unzip an archive located on a TFTP server or in the switch’s nonvolatile storage. If you specify a TFTP server as part of the filename with the backup command, the archive is copied directly to the TFTP server and not stored locally on the switch.

Both commands have options to specify the types of files you want to back up and restore:

•critical—Backs up or restores system files, including the configuration file used when booting, and certificate files. The size of an archive created by this option is generally 1MB or less. This is the default for the restore command.

•all—Backs up or restores the same files as the critical option, and all files in the user files area of nonvolatile storage. (The user files area contains the set of files listed in the file section of dir command output.) Archive files created by the all option are larger than files created by the critical option. The file size depends on the files in the
