Redundant Ring
Check to enable O-Ring topology.
Ring Master
Only one ring master is allowed in a ring. However, if more
than one switches are set to enable
Ring Master
, the switch
with the lowest MAC address will be the active ring master and
the others will be backup masters.

Coupling Ring
Check to enable
Coupling Ring
.
Coupling Ring
can divide a
big ring into two smaller rings to avoid network topology
changes affecting all switches. It is a good method for
connecting two rings.
Coupling Port
Ports for connecting multiple rings. A coupling ring needs four
switches to build an active and a backup link.
Links formed by the coupling ports will run in active/backup
mode.
Dual Homing
Check to enable
Dual Homing
. When
Dual Homing
is
enabled, the ring will be connected to normal switches through
two RSTP links (ex: backbone Switch). The two links work in
active/backup mode, and connect each ring to the normal
switches in RSTP mode.
Apply
Click to apply the configurations.
Note:
due to heavy computing loading, setting one switch as ring master and coupling ring at
the same time is not recommended.
