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. Also, user can identify the switch as the ring master from the R.M. LED panel of the LED panel on the switch.
The system also supports the coupling ring that can connect 2 or more X-Ring group for the redundant backup function and dual homing function that prevent connection lose between X-Ring group and upper level/core switch.
Enable X-Ring: Enable the X-Ring function. Mark the check box to enable the X-Ring function.
Enable Ring Master: Mark the check box to enable this machine to be the ring master.
1st & 2nd Ring Ports: Pull down the selection menu to assign two ports as the member ports. The 1st Ring Port and 2nd Ring Port are basically assigned to be forwarding ports except for the Ring Master switch. With the Ring Master switch, one of its two Ring Ports is the blocking port and another one is the forwarding port.
