Configuring Ais; Configuring Lm - HPE FlexFabric 5700 Series Configuration Manual

Step
1. Find the path between a
source MEP and a target
MEP.
2. Enter system view.
3. Enable LT messages
automatic sending.

Configuring AIS

The AIS function suppresses the number of error alarms reported by MEPs.
For a MEP in the service instance to send AIS frames, set the AIS frame transmission level to be
higher than the MD level of the MEP.
Enable AIS and configure a correct AIS frame transmission level on the target MEP, so the target
MEP can perform the following tasks:
•
Suppress the error alarms.
•
Send the AIS frame to the MD of a higher level.
If you enable AIS but do not configure a correct AIS frame transmission level, the target MEP can
suppress the error alarms, but cannot send the AIS frames.
To configure AIS:
Step
1. Enter system view.
2. Enable AIS.
3. Configure the AIS frame
transmission level.
4. Configure the AIS frame
transmission interval.

Configuring LM

The LM function measures frame loss between MEPs. Frame loss statistics include the number of
lost frames, the frame loss ratio, and the average number of lost frames for the source and target
MEPs.
To configure LM:
Task
Configure LM.
