z Configure CC to monitor the connectivity among all the MEPs in MD_A and MD_B. Configure to
use LB to locate link faults or use LT to identify the paths between source and destination MEPs
or locate faults after the whole network status is obtained.

Configuration procedure
1) Configure a VLAN and assign ports to it
On each device shown in Figure 5-6 , create VLAN 100 and assign ports GigabitEthernet2/0/1 through
GigabitEthernet2/0/4 to VLAN 100.
2) Enable CFD
# Enable CFD on Device A.
<DeviceA> system-view
[DeviceA] cfd enable
Enable CFD on Device B through Device E using the same method.
3) Configure service instances
# Create MD_A (level 5) on Device A, create MA_A, which serves VLAN 100, in MD_A, and create
service instance 1 for MD_A and MA_A.
[DeviceA] cfd md MD_A level 5
[DeviceA] cfd ma MA_A md MD_A vlan 100
[DeviceA] cfd service-instance 1 md MD_A ma MA_A
Configure Device E as you configure Device A.
# Create MD_A (level 5) on Device B, create MA_A, which serves VLAN 100, in MD_A, and then
create service instance 1 for MD_A and MA_A; in addition, create MD_B (level 3), create MA_B, which
serves VLAN 100, in MD_B, and then create service instance 2 for MD_B and MA_B.
[DeviceB] cfd md MD_A level 5
[DeviceB] cfd ma MA_A md MD_A vlan 100
[DeviceB] cfd service-instance 1 md MD_A ma MA_A
[DeviceB] cfd md MD_B level 3
[DeviceB] cfd ma MA_B md MD_B vlan 100
[DeviceB] cfd service-instance 2 md MD_B ma MA_B
Configure Device D as you configure Device B.
