4.2.6 Backup and Restore
With Backup command, you can save current configuration file saved in the
switch’s flash to admin PC or TFTP server. This will allow you to go to Restore
command later to restore the configuration file back to the switch. Before you
restore the configuration file, you must place the backup configuration file in the
PC or TFTP server. The switch will then download this file back to the flash.
There are 2 modes for users to backup/restore the configuration file, Local File
mode and TFTP Server mode.
Local File mode: In this mode, the switch acts as the file server. Users can browse
the target folder and then type the file name to backup the configuration. Users
can also browse the target folder and select existed configuration file to restore
the configuration back to the switch. This mode is only provided by Web UI while
CLI is not supported.
