ERPS (G.8032) Configuration

Ethernet Ring Protection Switching (ERPS) is a standard protocol issued by the ITU-T to prevent loops on ring networks. It meets carrier-class reliability requirements for network convergence. All ERPS-capable devices on a ring network can communicate.

Overview of ERPS: ERPS is a standard protocol issued by the ITU-T to prevent loops on ring networks. It can be used for communication between Huawei and non-Huawei devices on a ring network.

Configuration Precautions for ERPS (G.8032)

Summary of ERPS Configuration Tasks: This section describes ERPS features supported by the NetEngine 8000 F.

(Optional) Configuring Timers for an ERPS Ring: To prevent the blocked port from alternating between Up and Down in case a faulty device or link on an ERPS ring recovers, enable timers for the ERPS ring to reduce the traffic interruption time.

Configuring ERPSv1: ERPS eliminates loops on an Ethernet ring network when no faulty links exist and promptly restores communication if a link fault occurs. ERPSv1 supports only single rings.

Configuring ERPSv2: ERPS eliminates loops on an Ethernet ring network when no faulty links exist and promptly restores communication if a link fault occurs. ERPSv2, compatible with ERPSv1, supports multi-ring topologies and association with CFM, in addition to ERPSv1 functions, such as single ring topologies and multi-instance.

Maintaining ERPS: This section describes how to maintain ERPS.

Configuration Examples for ERPS: This section provides ERPS configuration examples.
