Description
Enable Ring
Check to enable O-Ring topology.
Enable 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.
1st Ring Port
The primary port when the switch is ring master
2nd Ring Port
The backup port when the switch is ring master
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.
Couple 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.
Enable 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 activate the configurations.
Note:
due to heavy loading, setting one switch as ring master and coupling ring at the same
time is not recommended.
