Example for Configuring VLAN-based Y.1731 Two-way Frame Delay Measurement
Networking Requirements
As networks continue to rapidly develop and applications become more and more diversified, various value-added services such as IPTV, video conferencing, and VOIP are becoming more widely used. Link connectivity and network performance determine QoS on bearer networks. Therefore, performance monitoring is especially important for service transmission.
In Figure 10-7, CFM is deployed to measure link connectivity between the CEs. To provide high-quality video services, carriers need to monitor the two-way delay over mobile bearer links in real time, while monitoring link connectivity. Monitoring the two-way delay over mobile bearer links allows the carriers to respond quickly to video service quality deterioration.
Configuration Roadmap
Configure basic CFM functions on the CEs.
Configure CE2 to receive DMMs.
Configure two-way frame delay measurement for the end-to-end link between the CEs.
- Configure on-demand two-way frame delay measurement for the end-to-end link between the CEs to periodically collect statistics about the delay in frame transmission.
- Configure proactive two-way frame delay measurement for the end-to-end link between the CEs to continuously collect statistics about the delay in frame transmission.
Procedure
- Configure basic Ethernet CFM functions on CE1 and CE2. Create an MD named md3 and an MA named ma3, and bind the MA to the VLAN.

- Configure two-way frame delay measurement for the end-to-end link between the CEs.
Configure on-demand two-way frame delay measurement for the end-to-end link between the CEs.
# Configure on-demand two-way frame delay measurement on CE1.

Configure proactive two-way frame delay measurement for the end-to-end link between the CEs.
# Configure proactive two-way frame delay measurement on CE1.

- Verify the configuration.
# After the configurations are complete, run the display y1731 statistic-type twoway-delay test-id 1 command on CE1. You can view the statistics about the two-way frame delay.
