more switches that set Ring Master to enable, the switch with the

Backup Masters.
1st Ring Port The primary port, when this switch is Ring Master.
2nd Ring Port The backup port, when this switch is Ring Master.
Enable Coupling Ring Mark to enable the Coupling Ring. Coupling Ring can be used to
divide a big ring into two smaller rings to avoid affecting all switches
when network topology changes. It is a good application for
connecting two Rings.

need four switch to build an active and a backup link.
Set a port as coupling port. The coupled four ports of four switches
will be run at active/backup mode.

to transmit control signals.
Enable Dual Homing Mark to enable Dual Homing. By selecting Dual Homing mode,
ComRing will be connected to normal switches through two RSTP

mode, and connect each ComRing to the normal switches in RSTP
mode.

Note: ComNet does not recommend setting one switch as a Ring Master and a Coupling Ring
at the same time due to heavy load.
