Introduction

The following information describes a typical configuration example of using Ethernet Operation, Administration, and Maintenance (OAM) to monitor Ethernet Ring Protection Switching (ERPS) ring link performance.

Ethernet OAM is a tool for monitoring network faults. It can monitor the link status between two directly connected devices.

Ethernet Ring Protection Switching (ERPS) is an Ethernet ring network link layer technology that provides high reliability and stability. It can prevent broadcast storms caused by data loops when the Ethernet ring is intact, and can quickly restore communication paths between nodes on the ring network when a link fault occurs. It provides high convergence speed.

Prerequisites

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

The following information is provided based on the assumption that you have basic knowledge of Ethernet OAM and ERPS.

Example: Using Ethernet OAM to monitor ERPS ring link performance

Networking configuration

As shown in Figure 1, to improve network resource utilization and implement load balancing among links, configure ERPS as follows:

· Configure ERPS instances 1 and 2 on the ERPS ring.

· For ERPS instance 1, configure the following items:

¡ Configure Device A as the owner node.

¡ Configure the link between Devices A and Device B as the RPL.

¡ Configure VLAN 100 as the control VLAN.

¡ Configure VLANs 1 to 30 as the protected VLANs.

· For ERPS instance 2, configure the following items:

¡ Configure Device A as the owner node.

¡ Configure the link between Devices C and Device D as the RPL.

¡ Configure VLAN 100 as the control VLAN.

¡ Configure VLANs 31 to 60 as the protected VLANs.

Use Ethernet OAM to monitor the ERPS ring link status and determine if the network link reliability meets the requirements.

· Enable automatic detection of the connectivity of ERPS ring links.

· Check whether a critical link event has occurred on the ERPS ring.

· Check the statistics of Ethernet OAM link events to determine the ERPS ring status.

Analysis

An ERPS ring supports multiple ERPS instances. An ERPS instance is a logical ring to process service and protocol packets. Each ERPS instance has its own owner node and maintains its own state and data. In this example, instance 1 and instance 2 are configured on ERPS ring 1.

Common link events that can be monitored by Ethernet OAM include errored symbol events, errored frame events, errored frame period events, and errored frame seconds events. By default, the interfaces with Ethernet OAM enabled use global configuration for common link event detection parameters. To meet the detection requirements in specific network conditions, you can change the detection parameters as needed. In this example, the parameters for detecting errored frame events are changed.

Software versions used

This configuration example was created and verified on Release 5210 or later versions of S12500R.

Restrictions and guidelines

In this example, some physical interfaces must operate in bridge mode. By default, the physical interfaces on the device operate in route mode. Use the port link-mode command in the corresponding interface view to switch the interface's operating mode as needed.

By default, the interfaces on the device are in administratively down (ADM) state. You must bring up the interfaces by using the undo shutdown command in the corresponding interface view as needed.

ERPS does not provide an election mechanism. To implement ring detection and protection, configure all nodes correctly.

Do not change the Ethernet OAM connection mode on Ethernet OAM-enabled interface. To change the Ethernet OAM connection mode on an interface, first disable Ethernet OAM on that interface.

As a best practice, do not enable Ethernet OAM remote loopback on ERPS ring member ports, as it might cause a short-term broadcast storm.

The protection VLANs of different ERPS instances must be different.
