When you make a change to the Topology view, choose View > Save Topology Layout to make it permanent (in effect after the switch is powered off and powered on again).
To change the order of switches in the Front Panel view, choose View > Arrange Front Panel and use the Arrange Front Panel window.
To make any other change permanent:
Note: Catalyst 1900 and 2820 switches automatically save configuration changes to nonvolatile memory, so Step 2 is not required. Allow several seconds for changes to be saved to nonvolatile memory before resetting or turning off these switches.
