G.8032 Ethernet Ring Protection Switching Feature Overview and Configuration Guide

G.8032 is an International Telecommunication Union (ITU) standard for Ethernet Ring Protection Switching (ERPS). It prevents loops on a per-VLAN basis with networks that are wired in a simple ring topology, and (with G.8032 Version 2) multiple ring and ladder topologies.

G.8032 offers a rapid detection and recovery time if a link or node fails, in the order of 50 ms, depending on configuration.

This guide describes G.8032 Ethernet Ring Protection Switching (ERPS) and how to configure it.
