ERPS Commands

In this chapter

The G.8032 recommendation, also referred to as Ethernet Ring Protection Switching (ERPS), can
be used to increase the availability and robustness of Ethernet rings.

This chapter describes commands used to configure ERPS.

Configuration Guidelines for ERPS

1. Create an ERPS ring: Create a ring using the

erps domain

command. The ring name is used as

an index in the G.8032 database.

2. Configure the east and west interfaces: Each node on the ring connects to it through two ring

ports. Use the

ring-port

command to configure one port connected to the next node in the ring

to the east (or clockwise direction); and then use the

ring-port

command again to configure

another port facing west in the ring.
