Coupling Ring Application
There may be more than one X-ring group in the network. The Coupling Ring function
can connect each X-Ring for redundant backup. It ensures the transmission between
two ring groups, therefore reducing failure.

Dual Homing Application
The Dual Homing function is used to prevent the connection loss from between X-ring
groups and upper level/core switches. Two ports are assigned as the Dual Homing port
that is used as a backup port in the X-ring group. The Dual Homing function is only
available when the X-ring function is active. Each X-ring group has only one Dual
Home port.
Note:
When using the Dual Homing application, upper level switches must enable
RSTP protocol. The following illustrates the Dual Homing application:
