EPSR State and Settings

To display the EPSR state, the attached VLANs, the ring ports, and the timer values, use the command:

show epsr

The following diagram shows the output for a master node in a ring that is in a state of Complete. As well as giving the state as Complete, it also shows that port 1 is the primary port and port 2 is the secondary port. Note that the secondary port is blocked, so does not forward packets over the data VLAN (vlan2).
