Example 1: A Basic Ring

6.Create the EPSR domain

This step creates the domain, specifying that this switch is the transit node. It also specifies which VLAN is the control VLAN.

create epsr=test mode=transit controlvlan=vlan1000

7.Add the data VLAN to the domain

add epsr=test datavlan=vlan2

8.Enable EPSR

enable epsr=test
