X-Ring
X-Ring provides network redundancy similar to the Spanning Tree and
Rapid Spanning Tree Protocols. However, recovery time is greatly reduced
when the X-Ring protocol is used. The protocol identifies one switch as the
Ring Master. Packets are blocked from the redundant path unless a ring
member becomes disconnected from the rest of the network. When this
happens, the protocol automatically restores connectivity using the
redundant path.
In the X-Ring topology, every switch should enable X-Ring function and
assign two member ports to the ring. Only one switch in the X-Ring group
would be set as the backup switch. Other switches are called working
switches and their two member ports are called working ports. If a network
