To perform packet loss performance measurement on a point-to-multipoint or multipoint-to-multipoint links, deploy single-ended synthetic loss measurement (SLM) to monitor the link quality.
To collect performance statistics about frame loss on the PW or AC side at a time or periodically, configure on-demand single-ended SLM through the VPLS.
To continuously collect performance statistics about frame loss on the PW or AC side, configure proactive single-ended SLM through the VPLS.
Configure on-demand single-ended SLM on the PW side.
Perform the following steps on the devices at both ends of a PW where on-demand single-ended SLM will be implemented:
Run system-view
The system view is displayed.
Run cfm md md-name
The MD view is displayed.
Run ma ma-name
The MA view is displayed.
Run map vsi vsi-name
The MA is bound to a VSI.
Configure a MEP according to Table 1.
