Network requirements
As shown in Figure 5:
• The network comprises five devices and is divided into two MDs: MD_A (level 5) and MD_B
(level 3). All ports belong to VLAN 100, and the MAs in the two MDs all serve VLAN 100.
Assume that the MAC addresses of Device A through Device E are 0010-FC01-6511,
0010-FC02-6512, 0010-FC03-6513, 0010-FC04-6514, and 0010-FC05-6515, respectively.
• MD_A has three edge ports: Ten-GigabitEthernet 1/0/1 on Device A, Ten-GigabitEthernet 1/0/3
on Device D, and Ten-GigabitEthernet 1/0/4 on Device E, and they are all inward-facing MEPs.
MD_B has two edge ports: Ten-GigabitEthernet 1/0/3 on Device B and Ten-GigabitEthernet
1/0/1 on Device D, and they are both outward-facing MEPs.
• In MD_A, Device B is designed to have MIPs when its port is configured with low level MEPs.
Port Ten-GigabitEthernet 1/0/3 is configured with MEPs of MD_B, and the MIPs of MD_A can
be configured on this port. You should configure the MIP generation rule of MD_A as explicit.
• The MIPs of MD_B are designed on Device C, and are configured on all ports. You must
configure the MIP generation rule as default.
• Configure CC to monitor the connectivity among all the MEPs in MD_A and MD_B. Configure
LB to locate link faults, and use the AIS and EAIS functions to suppress the error alarms that
are reported.
• After the status information for the entire network is obtained, use LT, LM, one-way DM,
two-way DM, and TST to detect link faults.
