Automatic Synchronization

As with manual synchronization, use the Redundant Appliance Synchronization screen to synchronize the configurations from your primary server to the secondary server.

Use the left pane of this screen to provide the details for the primary Extreme AirDefense appliance.

The right pane of this screen enables you to automatically synchronize configurations from the primary server on a pre defined schedule.

Before you can synchronize between two devices, you must designate the current device as a redundant device. Select the Designate this as a Secondary (redundant) device... option to indicate that this device is a redundant server. When this option is not selected, this device becomes the primary server and all the fields in this screen are disabled.

To automatically synchronize this Extreme AirDefense appliance with a primary server, provide the following information:
