Dual Homing Application
Dual Homing is a function to prevent the connection breaking between an X-Ring group
and an upper level/core switch. Assign two ports to be the Dual Homing port that is the
backup port in an X-Ring group. The Dual Homing function works only when the X-Ring
function is active. Each X-Ring group has only one Dual Homing port.
[NOTE] In a Dual Homing application architecture, the Rapid Spanning Tree protocol of
the upper level switches must be enabled.
