5. Remove the ring ports from the default VLAN
delete vlan=1 port=1-2
6. Create the EPSR domain
This step creates the domain, specifying that this switch is the master node. It also specifies
which VLAN is the control VLAN and which port is the primary port.
create epsr=test mode=master controlvlan=vlan1000 primaryport=1
7. Add the data VLAN to the domain
add epsr=test datavlan=vlan2
8. Enable EPSR
enable epsr=test
Configure the Transit Nodes (B and C)
Each of the transit nodes has the same EPSR configuration in this example.
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 both the control VLAN and all data VLANs.
add vlan=2 port=1-2 frame=tagged
5. Remove the ring ports from the default VLAN
delete vlan=1 port=1-2
