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
Used 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.

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.
