ais interval

Function

The ais interval command sets the interval at which a MEP in an MA sends AIS PDUs to a MEP in a high-level MA.

The undo ais interval command restores the default interval.

By default, the interval at which AIS PDUs are sent is 1s.

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 interval at which AIS PDUs are sent according to the networking.

Precautions

The ais interval 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 interval at which AIS PDUs are sent in ma1 to 60s.
