Super ring

Super ring provide a faster redundant recovery than Spanning Tree topology. The action

is similar with STP or RSTP, but the algorithms not the same.

In the Super ring topology, every switch should enable super ring function and assign two

member ports in the ring. Only one switch in the super ring group would be set as a

backup switch that one of two member ports would be blocking, called backup port, and

another port is called working port. Other switches are called working switches and their

two member ports are called working ports. When the network connection failure, the

backup port will automatically become a working port to recovery the failure.

The switch can be set as the ring master or slave. The ring master has the rights to

negotiate and place command to other switches in the super ring group. If there are 2 or

more switches are in master mode, then software will select the switch with lowest MAC

address number as the ring master.
