Only one ring master
is allowed in a ring. However, if more than
one switch are set to enable

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.

Due to heavy computing loading, setting one switch as ring master and coupling ring
at the same time is not recommended.
