Configuring AIS
The AIS function suppresses the number of error alarms reported by MEPs.
Follow these steps to configure AIS:
Required
Disabled by default.
Configure the AIS frame
transmission level
cfd ais level level-value service-
instance instance-id
Required
Not configured by default.
Configure the AIS frame
transmission interval
cfd ais period period-value
service-instance instance-id
Optional
1 second by default.
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:
cfd slm service-instance instance-id mep mep-id
{ target-mac mac-address | target-mep target-
mep-id } [ number number ]
Required
Disabled by default.
CAUTION:
The LM function takes effect only in CFD IEEE 802.1ag.
