Saving Your Parameter Changes
When you make a change to a switch parameter, the change is, in most
cases, immediately activated as soon as you click the Apply button.
However, a change to a switch parameter is initially saved only to
temporary memory. It is lost the next time you reset or power cycle the
unit. To permanently save a change, you must click the Save Config
button in the Configuration menu, shown in Figure 4. This updates the
switch’s active configuration file. A change saved to the active
configuration file is retained even when the unit is powered off or reset.
This menu option is displayed only after you have made a configuration
change. After you click Save Config, your changes are added to the
active configuration file and the option is removed from the menu.
