2.9 Dual Homing Application

The Dual Homing function is to prevent the connection loss between the particular X-Ring group and the
upper level/core switch. Assign one port, and only one, to be the Dual Homing port that is the backup
port in each single X-Ring group. The Dual Homing function only works when the X-Ring function is
active.

Note

The Ethernet switches with firmware version before v3.0 use the X-Ring
function that has the limitations as follows. However, the ones with
firmware version after v3.0 (included) use the X-Ring Pro function that
gets rid of the limitations.

1. In Dual Homing application architecture, the upper level switches need

to enable their Rapid Spanning Tree protocol.

2. The switches to be configured as members of the Dual Homing group

cannot be the X-Ring Master device of their X-ring group.

3. As the figure illustrated above, Dual Homing only supports two X-ring

groups.
