ERPS (G.8032) Configuration
This chapter describes how to configure Ethernet Ring Protection Switching (ERPS). ERPS is a protocol defined by the International Telecommunication Union - Telecommunication Standardization Sector (ITU-T) to eliminate loops at Layer 2. It implements convergence of carrier-class reliability standards, and allows all ERPS-capable devices on a ring network to communicate.

- Configuring ERPSv1
If there is no link fault on a ring network, ERPS can eliminate loops on the Ethernet network. If a link fault occurs on the ring network, ERPS can quickly restore communication between nodes on the ring network. - Configuring ERPSv2
When there is no faulty link on a ring network, Ethernet Ring Protection Switching (ERPS) can eliminate loops on the network. When a link fails on the ring network, ERPS can immediately restore communication between nodes on the network. ERPSv2, compatible with ERPSv1, supports multi-ring topologies and association with connectivity fault management (CFM), in addition to ERPSv1 functions such as single ring topologies and multi-instance. - Maintaining ERPS
