A Maintenance Association (MA) is part of an MD. An MD can

be divided into one or multiple MAs.

The Maintenance Domain (MD) refers to the network or the part

of the network for which connectivity is managed by CFM. The

devices in an MD are managed by a single ISP.

A Maintenance association End Point (MEP) is an end point within

There is a MEP database on each device enabled with Ethernet

CFM. Each MEP database contains the local MEPs and RMEPs.

A Maintenance association Intermediate Point (MIP) is an

intermediate point within an MA.

Either a MEP or a MIP is called a Maintenance Point (MP).
