ERPS C
OMMANDS
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.
