b) MIP

Maintenance association intermediate point (MIP) can handle and respond to CFM packets. The MA and MD

that a MIP belongs to define the VLAN attribute and level of the packets received.

Figure 3 demonstrates a grading example of CFM module. In the figure, there are six devices, labeled as 1 to 6

respectively. Suppose each device has two ports, and MEPs and MIPs are configured on some of these ports. Four

levels of MDs are designed in this example, the bigger the number, the higher the level and the larger the area

covered. In this example, the X port of device 2 is configured with the following MPs: a level 5 MEP, a level 3

inbound MEP, a level 2 inbound MEP, and a level 0 outbound MEP.
