IGMP Configuration interface

X-Ring

X-Ring provides a faster redundant recovery than Spanning Tree topology. The action is

similar to STP or RSTP, but the algorithms not the same.

In the X-Ring topology, every switch should enable X-Ring function and assign two

member ports in the ring. Only one switch in the X-Ring group would be set as a master

switch that would be blocked, called backup port, and another port is called working port.

Other switches in the X-Ring group are called working switches and their two member

ports are called working ports. When the failure of network connection occurs, the

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

The switch supports the function and interface for setting the switch as the ring-master or

slave mode. The ring-master can negotiate and place command to other switches in the

X-Ring group. If there are 2 or more switches in master mode, then software will select

the switch with lowest MAC address number as the ring master. The X-Ring master ring

mode will be enabled by the X-Ring configuration interface.
