5.4.6 Checking the Configuration
After the two-way frame delay measurement is configured in a VLAN, you can view the statistics
about the delay in bidirectional service traffic transmission in the VLAN.
Prerequisite
All the configurations of the two-way frame delay measurement in a VLAN are complete.
Procedure
l
----End
Example
After the configurations, run the display y1731 statistic-type command on the devices where
MEPs reside, and you can view the value of the average delay.

5.5 Configuration Examples
This section provides several configuration examples of Y.1731.
5.5.1 Example for Configuring the One-way Frame Delay
Measurement in a VLAN
When you need to estimate service qualities, you can configure the one-way frame delay
measurement on point-to-point MEPs to obtain the performance of the network.
Networking Requirements
As shown in
interval for sending DM frames is set to 10 seconds and the number of DM frames sent each
time is also set to 10.
Issue 01 (2011-10-26)
Run the display y1731 statistic-type twoway-delay md md-name ma ma-name [ count
count-value ] command to check the performance statistics collected through Y.1731.
