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.
TFTP Server
mode: In this mode, the switch acts as TFTP client. Before
you do so, make sure that your TFTP server is ready. Then please type the
IP address of TFTP Server and Backup configuration file name. This mode
can be used in both CLI and Web UI.
TFTP Server IP Address
: You need to key in the IP address of your TFTP
Server here.
Backup/Restore File Name
: Please type the correct file name of the
configuration file..
Configuration File:
The configuration file of the switch is a pure text file.
You can open it by word/txt read file. You can also modify the file,
add/remove the configuration settings, and then restore back to the switch.
Startup Configuration File:
After you saved the running-config to flash,
the new settings will be kept and work after power cycle. You can use
show
startup-config
to view it in CLI. The Backup command can only backup
such configuration file to your PC or TFTP server.
Once you finish selecting and configuring the settings, click on
Backup
or
Restore
to run
Technical Tip:

in the system. You can use Reset button, Reload command to reset the
system.

settings running by the system. The information shown here is the settings you
