Usage Guidelines

Usage Scenario

In MD nesting scenarios, if the MEP of a low-level MD detects a fault, the MEP sends an alarm to the NMS. After a specified period elapses, if the MEP of a high-level MD also detects the fault, the MEP sends an alarm that is the same as the one sent by the MEP of the low-level MD to the NMS. In this case, the MEP of the high-level MD needs to be suppressed from sending alarms to the NMS. You can enable the AIS function for the low-level and high-level MDs. After enabling the AIS function for the MDs, you can run the ais level command to set a level for AIS packets to be sent.

Prerequisites

An MD has been created using the cfm md command.
An MA has been created using the ma command.
The AIS function has been enabled using the ais enable command.

Example

# Create an MD named md1, create an MA named ma1 in the MD, and set a level for AIS packets to be sent to 2 in ma1.
