Chapter 3: Network Application
Coupling Ring Application
In the network, it may have more than one X-Ring group. By using the coupling ring
function, it can connect each X-Ring for the redundant backup. It can ensure the
transmissions between two ring groups not to fail. The following figure is a sample of
coupling ring application.
Dual Homing Application
Dual Homing function is to prevent the connection lose from between X-Ring group
and upper level/core switch. Assign two ports to be the Dual Homing port that is
backup port in the X-Ring group. The Dual Homing function only works when the X-
Ring function is active. Each X-Ring group only has one Dual Homing port.
NOTE:
In Dual Homing application architecture, the upper level switches need to
enable the Rapid Spanning Tree protocol.
