Example for Configuring Dual-ended Frame Loss Measurement in VPLS Networking
This section provides an example showing how to configure dual-ended frame loss measurement in VPLS networking.
Networking Requirements
As shown in Figure 1, CEs and PEs on end-to-end links support CC. Dual-ended frame loss measurement needs to be implemented to monitor the performance of end-to-end IP RAN links and measure frame loss on the links.
Configuration Roadmap
Configure dual-ended frame loss measurement for the PW between the PEs to continually collect frame loss statistics.
Configure dual-ended frame loss measurement for the AC between each PE and its attached CE to collect frame loss statistics.
Data Preparation
To complete the configuration, you need the following data:
Configure the name of a VSI and the IP address of the interface of a VPLS.
Configure the names of the MD and MA between PE1 and PE2 and between CE1 and PE1.
Configure a VLAN ID on CE interfaces for collecting AC-side packet statistics.
Configure the interval at which LM messages are sent.
Procedure
- Configure dual-ended frame loss measurement for the PW between the PEs.
Configure a VPLS connection.
Configure a VPLS connection between PE1 and PE2. The detailed configurations are not provided here. For details, see the chapter "VPLS Configuration" in the HUAWEI NetEngine 8000 F SeriesRouter Configuration Guide - VPN or configuration files in this example.
After completing the configuration, run the display vsi name vsi-name verbose command on each PE to view information about the related VSI and PW.

Configure basic Ethernet CFM functions on each PE. Specify the Ethernet CFM protocol in the version of IEEE Standard 802.1ag-2007. Create an MD named md1 and an MA named ma1, and bind the MA to the VSI.
