7. Configure AIS:
# Enable AIS on Device B, and configure the AIS frame transmission level as 2 and AIS frame
transmission interval as 1 second in service instance 2.
[DeviceB] cfd ais enable
[DeviceB] cfd ais level 5 service-instance 2
[DeviceB] cfd ais period 1 service-instance 2
Verifying the configuration
1. Verify the LB function:
When the CC function detects a link fault, use the LB function to locate the fault.
# Enable LB on Device A to check the status of the link between MEP 1001 and MEP 5001 in
service instance 1.

After the whole network status is obtained with the CC function, use the LT function to identify the
paths between source and target MEPs or locate faults.
2. Verify the LT function:
# Identify the path between MEP 1001 and MEP 5001 in service instance 1 on Device A.
