19ERPS Commands
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.
