In the Super ring topology, every switch should enable super ring function and assign two member ports in the ring. Only one switch in the super ring group would be set as a backup switch that one of two member ports would be blocking, called backup port, and another port is called working port. Other switches are called working switches and their two member ports are called working ports. When the network connection failure, the backup port will automatically become a working port to recovery the failure.
The switch can be set as the ring master or slave. The ring master has the rights to negotiate and place command to other switches in the super ring group. If there are 2 or more switches are in master mode, then software will select the switch with lowest MAC address number as the ring master.
The system also supports the coupling ring that can connect 2 or more super ring group for the redundant backup function.
Super ring: to enable the super ring function.
Ring Master: Enable means the switch is ring master. Disable means the switch is slave.
1st & 2nd Ring Ports: select two ports as the member ports. One port will be working port and one port will be the backup port. The system will automatically decide which port is working port and which port is backup port.
Coupling Ring: to enable the coupling ring function.
Coupling port: select the member port.
Control port: select the switch as the master switch in the coupling ring.
