Enable Ring • : To enable the X-Ring function, tick the checkbox beside the Enable Ring string
label. If this checkbox is not ticked, all the ring functions are unavailable.
Enable Ring Master: Tick the checkbox to enable this switch to be the ring master.
1st & 2nd Ring Ports: Pull down the selection menu to assign the ports as the member ports.
1st Ring Port is the working port and 2nd Ring Port is the backup port. When 1st Ring
Port fails, the system will automatically upgrade the 2nd Ring Port to be the working port.
Enable Couple Ring • : To enable the couple ring function, tick the checkbox beside the Enable
Couple Ring string label.
Couple Port: Assign the member port which is connected to the other ring group.
Control Port: When the Enable Couple Ring checkbox is ticked, you have to assign the control
port to form a couple-ring group between the two X-rings.
Enable Dual Ring • : When this check box is ticked, the ‘ Enable Ring Master’ check box will then
also be enabled by the system, which means this equipment is assigned as the Ring Master. The Dual
Ring differs from the Couple Ring in that it only needs a unit to form a redundant linking system
of two rings.
And then, click to have the configuration take effect.

[note]
1. When the X-Ring function enabled, the user must disable the RSTP. The X-Ring
function and RSTP function cannot exist on a switch at the same time.
2. Remember to execute the “Save Configuration” action, otherwise the new
configuration will lose when switch powers off.
