79X-RingX-Ring provides a faster redundant recovery than Spanning Tree topology. The action issimilar to STP or RSTP, but the algorithms not the same.In the X-Ring topology, every switch should enable X-Ring function and assign twomember ports in the ring. Only one switch in the X-Ring group would be set as a backupswitch that would be blocked, called backup port, and another port is called working port.Other switches are called working switches and their two member ports are calledworking ports. When the failure of network connection occurs, the backup port willautomatically become a working port to recovery the failure.The switch supports one Dipswitch for setting the switch as the ring master or slavemode. The ring master can negotiate and place command to other switches in theX-Ring group. If there are 2 or more switches in master mode, then software will selectthe switch with lowest MAC address number as the ring master. The X-Ring master ringmode will be enabled by the DIP Switch. When the switch is set to the master ring mode,the X-Ring configuration interface will display the switch as the master ring message.Also, user can identify the switch as the ring master from the R.M. LED panel of the LEDpanel on the switch.The system also supports the coupling ring that can connect 2 or more X-Ring group forthe redundant backup function and dual homing function that prevent connection losebetween X-Ring group and upper level/core switch. Enable X-Ring: To enable the X-Ring function. Marking the check box to enable theX-Ring function. 1st & 2nd Ring Ports: Assign two ports as the member ports. One port will beworking port and the other one will be the backup port. The system will automaticallydecide which port is working port and which port is backup port. Enable Coupling Ring: To enable the coupling ring function. Marking the checkbox to enable the coupling ring function. Coupling port: Assign the member port.
