Description
iRing
Check to enable iRing topology.
Ring Master
Only one ring master is allowed in a ring. However, if more than
one switch is 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
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.
Dual Homing
Check to enable
Dual Homing
. When
Dual Homing
is enabled, the
ring will be connected to normal switches through two RSTP links
(e.g., a backbone switch). The two links work in active/backup
mode, and connect each ring to the normal switches in RSTP mode.

iChain
iChain provides the ability to add network redundancy to any existing backbone network. iChain allows
multiple redundant network rings based on different redundancy protocols to join and function together
as a larger and more robust compound network topology.
