4.3 Dual Homing Application
The Dual Homing function prevents lost connection between an X-Ring group and an
upper level/core switch. Assign two ports to be the Dual Homing ports 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.
