Configuration Upload and Download
When you make changes to the switch, the configuration information is stored in a file on the
switch. You can backup the configuration by uploading the configuration file from the switch
to an administrative system. You can download a saved configuration file from the
administrative system to the switch. The configuration file you download to the switch
overwrites the running configuration on the switch.
Configuration upload and download is useful if you want to save a copy of the current switch
configuration (Upload Conf
iguration) before you make changes. If you do not like the
changes, you can use the Download Configuration option to restore the switch to the settings
in the saved configuration file.
To save a copy of the current switch configuration on your administrative system:
1. Click the Maintena
nce tab and select the device with the configuration to save.
2. Click Upl
oad Configuration.
3. From t
he Browse for Folder window that appears, navigate to and select the folder where
you want to store the configuration file.
4. Click OK.
5. Ente
r the switch password and click Apply.
The file is uploaded to the administrative comp
uter as a *.cfg file. You can open it and
view the contents with a text editor.
