Configure the Master Node (A)

1.Create the control VLAN

create vlan=vlan1000 vid=1000

2.Add the ring ports to the control VLAN

add vlan=1000 port=1-2 frame=tagged

3.Create the data VLAN

create vlan=vlan2 vid=2

4.Add the ring ports to the data VLAN

The two ring ports must belong to the control VLAN and all data VLANs.

add vlan=2 port=1-2 frame=tagged
