Coupling Ring
If you already have two O-Ring topologies and would like to connect the rings, you can form
them into a coupling ring. All you need to do is select two switches from each ring to be
connected, for example, switch A and B from Ring 1 and switch C and D from ring 2. Decide
which port on each switch to be used as the coupling port and then link them together, for
example, port 1 of switch A to port 2 of switch C and port 1 of switch B to port 2 of switch D.
Then, enable Coupling Ring option by checking the checkbox on the management page and
select the coupling ring in correspondence to the connected port. For more information on port
setting, please refer to 4.1.2 Configurations. Once the setting is completed, one of the
connections will act as the main path while the other will act as the backup path.
Dual Homing
If you want to connect your ring topology to a RSTP network environment, you can use dual
homing. Choose two switches (Switch A & B) from the ring for connecting to the switches in the
RSTP network (Ciscos switches). The connection of one of the switches (Switch A or B) will
act as the primary path, while the other will act as the backup path that is activated when the
primary path connection fails.
