Configuring AIS

The AIS function suppresses the number of error alarms reported by MEPs.
Follow these steps to configure AIS:
To do...
Enter system view
Enable AIS
Configure the AIS frame
transmission level
Configure the AIS frame
transmission interval
NOTE:

To make an MEP in the service instance send AIS frames, you must configure the AIS frame transmission level to
be higher than the MD level of the MEP.

Enable AIS and configure the proper AIS frame transmission level on the target MEP, so the target MEP can
suppress the error alarms and send the AIS frame to the MD of a higher level. If you enable AIS but do not
configure the proper AIS frame transmission level on the target MEP, the target MEP can suppress the error
alarms, but cannot send the AIS frames.

Configuring LM

The LM function measures frame loss between MEPs, including the number of lost frames, the frame loss
ratio, and the average number of lost frames for the source and target MEPs.
Follow these steps to configure LM:
To do...
Enter system view
Configure LM
CAUTION:
The LM function takes effect only in CFD IEEE 802.1ag.
