Ethernet OAM at the
Link Level
Ethernet OAM at the link level, such as Ethernet in the First Mile
OAM (EFM OAM) defined in IEEE 802.3ah, provides the
following functions for the link between the two directly connected
devices: Link continuity check, Link monitoring, Remote failure
indication, Remote loopback.
Ethernet OAM at the
Network Level
Ethernet OAM at the network level, such as Ethernet Connectivity
Fault Management (CFM) defined in IEEE 802.1ag, provides the
following functions for the network: Fault detection, Fault
notification, Fault verification, and Fault location.

M
MA
A Maintenance Association (MA) is part of an MD. An MD can
be divided into one or multiple MAs.
MD
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.
MEP
A Maintenance association End Point (MEP) is an end point within
an MA.
MEP Database
There is a MEP database on each device enabled with Ethernet
CFM. Each MEP database contains the local MEPs and RMEPs.
MIP
A Maintenance association Intermediate Point (MIP) is an
intermediate point within an MA.
MP
Either a MEP or a MIP is called a Maintenance Point (MP).
MTBF
Mean Time Between Failure
