Dual Homing Application
Dual Homing function is to prevent the connection loss 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.
