The undo ais level command deletes the level of AIS PDUs to be sent by a MEP in an MA.

Usage Guidelines

Usage Scenario

In MD nesting scenarios, if a MEP in a low-level MD detects a fault, the MEP sends a trap to the NMS. After a certain period, a MEP in the MD of a higher level also detects the fault and sends the same trap to the NMS. You can enable the AIS function in low-level and high-level MDs to suppress the MEP of the high-level MD from sending traps to the NMS. After AIS is enabled, set the level of AIS PDUs to be sent according to the networking.

Precautions

The ais level command can be used on only the device running IEEE Standard 802.1ag-2007.

Prerequisites

An MD has been created using the cfm md command, an MA has been created using the ma command, and AIS has been enabled using the ais enable command.

Example

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