Example 2: A Double Ring
This example adds to the previous ring by making two domains, as shown in the following
diagram.
The master node for domain 1 is the same as in the previous example (except that the
domain has been renamed).
create vlan=vlan1000 vid=1000
add vlan=1000 port=1-2 frame=tagged
create vlan=vlan2 vid=2
add vlan=2 port=1-2 frame=tagged
delete vlan=1 port=1-2
create epsr=domain1 mode=master controlvlan=vlan1000 primaryport=1
add epsr=domain1 datavlan=vlan2
enable epsr=domain1
