To configure Port Redundancy
The Redundant Port option displays all of the currently unassigned interfaces available. Select one of the interfaces; the default is None.
After an interface is selected as a Redundant Port, its configuration is governed by the primary interface and it cannot be configured independently. In the Interface Settings table, the interface's zone is displayed as Redundant Port, and the Configuration icon is removed.
Click OK. If Web Management has not been configured for the interface, a message displays.
