X-Ring2
X-Ring provides a faster redundant recovery than the Spanning Tree topology. The
action is similar to STP or RSTP, but the algorithms between them are not the same. To
configure an X-Ring group, the X-Ring function has to be enabled on each switch whose
two ports connecting to the ring group in which should be assigned as the member ports.
The two switches forming the last segment of a multi-device X-Ring group will
automatically be designated as master switches between which the connection is called
the backup path. Known as backup ports, the two ports of the backup path will be blocked.
Also, the user can identify whether the switch is the ring master device by checking the
LED indicator on the panel of the switch.
Other switches in the X-Ring group are naturally the working (forwarding) switches and
both their two member ports are working (forwarding) ports. If the failure of network
connection occurs, the backup ports of master switches (ring master devices) will
automatically become working (forwarding) ports to recover from the failure.
