13.2 Performance Monitoring (ITU-T Y.1731)
Performance monitoring provides monitoring functionality according to Y.1731
standard. The following measurements are supported:
 Frame delay measurements
 Frame jitter measurements
 Frame loss measurements
The Performance Monitoring is based on the CFM configuration.
The statistics are presented between the cfm-meps.
Loss and Delay measurements are given for the traffic on the CFM MA. Special 64
bytes packets are used for this purpose (DMM) in intervals of 10 seconds
(configurable).
To enable and monitor Y.1731 measurement for MEPs based on the Sample CFM
Configuration example above)
 Enable lm (loss measurement) and dm (delay measurement) on local (Link and
Customer levels):
set cfm-mep 1 1 1 lm enabled
set cfm-mep 1 1 1 dm enabled
set cfm-mep 2 2 1 lm enabled
set cfm-mep 2 2 1 dm enabled
