Configure AIS.
7.
# 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.

Verify the LB function.
1.
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.
[DeviceA] cfd loopback service-instance 1 mep 1001 target-mep 5001
Loopback to 0010-FC00-6512 with the sequence number start from 1001-43404:

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.
Verify the LT function.
2.
# Identify the path between MEP 1001 and MEP 5001 in service instance 1 on Device A.
[DeviceA] cfd linktrace service-instance 1 mep 1001 target-mep 5001
Linktrace to MEP 5001 with the sequence number 1001-43462
MAC Address
0010-FC00-6512
0010-FC00-6511
Verify the LM function.
3.
After the CC function obtains the status information of the entire network, use the LM function to test the
link status. For example:
# Test the frame loss from MEP 1001 to MEP 4002 in service instance 1 on Device A.
[DeviceA] cfd slm service-instance 1 mep 1001 target-mep 4002
