Redundant Ring
Mark to enable Ring.
Ring Master
There should be one and only one Ring Master in a ring.
However if there are two or more switches which set Ring Master
to enable, the switch with the lowest MAC address will be the
actual Ring Master and others will be Backup Masters.

Ring Port
The primary port, when this switch is Ring Master.
2
nd
Ring Port
The backup port, when this switch is Ring Master.
Coupling Ring
Mark to enable Coupling Ring. Coupling Ring can be used to
divide a big ring into two smaller rings to avoid effecting all
switches when network topology change. It is a good application
for connecting two Redundant Rings.
Coupling Port
Link to Coupling Port of the switch in another ring. Coupling
Ring 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.
Control Port
Link to Control Port of the switch of the same ring. Control Port
used to transmit control signals.
Dual Homing
Mark to enable Dual Homing. By selecting Dual Homing mode,
Redundant Ring will be connected to normal switches through
two RSTP links (ex: backbone Switch). The two links work as
active/backup mode, and connect each Redundant Ring to the
normal switches in RSTP mode.

Note:
We don’t suggest you to set one switch as a Ring Master and a Coupling Ring at the same time due to heavy
load.
5.1.4.3 RSTP
The Rapid Spanning Tree Protocol (RSTP) is an evolution of the Spanning Tree Protocol.
It provides faster spanning tree convergence after a topology change. The system also
supports STP and the system will auto detect the connected device that is running STP or
RSTP protocol.
RSTP setting
You can enable/disable the RSTP function, and set the parameters for each port.
