Example 3: EPSR and RSTP
This example uses EPSR to protect one ring and RSTP to protect another overlapping ring.
1. Configure the master node (switch A) for the EPSR domain
The master node is the same as in the previous example.
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
