Abstract:

A method to link aggregate over independent redundant switches is provided for use in an apparatus including first, second, and third switches in a local area network (LAN). A first port of the first switch is connected to a first port of the second switch, a second port of the second switch is connected to a first port of the third switch, and a second port of the third switch is connected to a second port of the first switch. The method includes forming a first link aggregation group (LAG) between the first and second ports of the first switch; forming a second LAG between the first and second ports of the second switch; and applying a port forwarding rule to the first and second ports of the second switch, where the first switch is in an active mode and the second switch is in a standby mode.
