Example 1: A Basic Ring

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
