4. Verify the one-way DM function.
After the CC function obtains the status information of the entire network, use the one-way DM function to
test the one-way frame delay of a link. For example:
# Test the one-way frame delay from MEP 1001 to MEP 4002 in service instance 1 on Device A.
[DeviceA] cfd dm one-way service-instance 1 mep 1001 target-mep 4002
Info: 5 1DM frames process is done, please check the result on the remote device.
# Display the one-way DM result on MEP 4002 in service instance 1 on Device D.
[DeviceD] display cfd dm one-way history service-instance 1 mep 4002
Service instance: 1
MEP ID: 4002

5. Verify the two-way DM function.
After the CC function obtains the status information of the entire network, use the two-way DM function to
test the two-way frame delay of a link. For example:
# Test the two-way frame delay from MEP 1001 to MEP 4002 in service instance 1 on Device A.
[DeviceA] cfd dm two-way service-instance 1 mep 1001 target-mep 4002

6. Verify the TST function.
After the CC function obtains the status information of the entire network, use the TST function to test the
bit errors of a link. For example:
