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,
enable the X-Ring function 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.

X-Ring2 Configuration
»
Ring ID
: Specify a number ranging from 0 to 99 for identifying a given ring group.
»
1st Ring Port
: One of the two member ports of this switch connecting to the ring group. Use
the pull-down menu to select a port as the first ring port.
»
2nd Ring Port
: The other member port of this switch connecting to the ring group. Use the
pull-down menu to select a port as the second ring port.
»
1st Rdn Port
: Use the pull-down menu to select a port as the first redundant port.
»
1st Rdn Port ID
: Specify a number ranging from 0 to 99 for identifying the first redundant port.
»
2nd Rdn Port
: Use the pull-down menu to select a port as the second redundant port.
»
2nd Rdn Port ID
