loss-measure single-ended receive

Function

The loss-measure single-ended receive command enables a remote MEP to receive LMMs to implement single-ended frame loss measurement.

The undo loss-measure single-ended receive command cancels the configuration.

By default, the remote MEP in the MA is not configured to receive LMMs.

Usage Guidelines

Usage Scenario

To implement packet loss measurement to determine the link performance, you need to run the loss-measure single-ended receive command to configure the remote MEP to receive LMMs.

Prerequisites

The loss-measure single-ended receive command takes effect only after the following configurations are complete:

Run the cfm version standard command in the system view to specify IEEE Standard 802.1ag-2007 for CFM.
The CFM function is enabled globally by using the cfm enable command in the system view.
An MD is created by using the cfm md command in the system view.
An MA is created by using the ma command in the MD view.
A test instance is created by using the test-id command in the MD view.

Precautions

The loss-measure single-ended receive command applies only to VLL, VPLS, VLAN, and L2VPN accessing L3VPN scenarios.
