Configuring Ais; Configuring Lm; Configuring One-Way Dm - HP 5130 EI Series Configuration Manual

Step
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
transmission level.
4. Configure
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.

Configuring one-way DM

The one-way DM function measures the one-way frame delay between two MEPs, and monitors and
manages the link transmission performance.
