ERPS (Ethernet Ring Protection Switching) is the first industry standard (ITU-T G.8032) for Ethernet ring
protection switching. It is achieved by integrating mature Ethernet Operations, Administration, and
Maintenance (OAM)* functions and a simple automatic protection switching (APS) protocol for Ethernet ring
networks. ERPS provides sub-50ms failover for Ethernet traffic in a ring topology. It ensures that there are no
loops formed at the Ethernet layer.
One link within a ring, the ring Protection Link (RPL), will be blocked to avoid a Layer 2 loop. When there is a
failure, protection switching blocks the failed link and unblocks the RPL. When the failure clears, protection
switching blocks the RPL again and unblocks the link on which the failure is cleared.
The ERPS page allows user to configure the ERPS instance and profile configuration of the Switch.
