Example 1: A Basic Ring
This example builds a simple 3-switch ring with one data VLAN, as shown in the following
diagram. Control packets are transmitted around the ring on vlan1000 and data packets on
vlan2.
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
