Saving Changes
The management software applies the changes you make when you click
the Apply button on any web page. However, the management software
does not automatically save the changes you make to the configuration
file. You can save your changes to the configuration file each time that you
change a parameter, or save the changes after you are done with all your
changes and before you exit the web browser.
Note
If you do not save changes using the Save Configuration page, your
changes are lost when the switch is rebooted.
To save your configuration changes, perform the following procedure:
1. From the main menu, select Save Configuration.
The Save Configuration page is shown in Figure 3.
