Example for Configuring Single-ended Frame Loss Measurement in VLAN Networking

This section provides an example showing how to configure single-ended frame loss measurement in VLAN networking.

Networking Requirements

With the increasing popularization and wide application of the Internet, various value-added services such as IPTV, video conferencing, and VoIP services are widely deployed. Link connectivity and network performance determine the Quality of Services (QoS) on bearer networks. Therefore, performance monitoring is especially important for service transmission channels.

As shown in Figure 1, CFM is configured between each CEs. CCMs are not used to monitor link connectivity, preventing them from using a lot of network bandwidth resources. To provide high-quality video services, providers hope to monitor the unidirectional delay over mobile bearer links in real time, while monitoring link connectivity. Monitoring the unidirectional delay over mobile bearer links allows the providers to respond quickly to video service quality deterioration.

Interfaces 1 and 2 in this example are GE 0/1/1, GE 0/1/2 respectively.

Configuration Roadmap

The configuration roadmap is as follows:

Configure on-demand single-ended frame loss measurement for the end-to-end link between the CEs to periodically collect frame loss statistics.

Data Preparation

To complete the configuration, you need the following data:

Configure the VLAN ID of an interface belong to CE.
Configure the names of the MD and MA between CE1 and CE2.
Configure the interval at which LM messages are sent and the number of times when LM messages are sent.

Procedure

Configure basic Ethernet CFM functions and specify the MEP type as outward.

Configure basic Ethernet CFM functions on each CE. Specify the Ethernet CFM protocol in the version of IEEE Standard 802.1ag-2007. Create an MD named md3 and an MA named ma3, and bind the MA to the VLAN.

Configure the LMM reception function on CE2.

# Configure CE2.

[~CE2-md-md3-ma-ma3] loss-measure single-ended receive test-id 1
[*CE2-md-md3-ma-ma3] quit
[*CE2-md-md3] quit
[*CE2] commit

Enable on-demand single-ended frame loss measurement.

# Configure CE1.

[*CE1-md-md3-ma-ma3] quit
[*CE1-md-md3] quit

Verify the configuration.

Run the display y1731 statistic-type command on CE1 to view on-demand single-ended frame loss statistics.
