Command Usage
•
An ERPS ring containing one Control VLAN and one or more protected Data VLANs must be
configured, and the global ERPS function enabled on the switch (see
on page 963) before a ring can start running. Once enabled, the RPL owner
node and non-owner node state machines will start, and the ring will enter the active state.
•
When configuring a ring port, note these ports cannot be part of a spanning tree, nor can they
be members of a static or dynamic trunk.
Parameters
These parameters are displayed:

Node State – Shows the following ERPS states:
•

Idle – If all nodes in a ring are in this state, it means that all the links in the ring are up.
This state will switch to protection state if a link failure occurs.
•
Protection – If a node in this state, it means that a link failure has occurred. This state will
switch to idle state if all the failed links recover.

Admin Status – Activates the current ERPS ring.
Before enabling a ring, the global ERPS function should be enabled see (

owner specified, and the control VLAN configured.
Once enabled, the RPL owner node and non-owner node state machines will start, and the ring
will enter idle state if no signal failures are detected.
