Maintenance Point (MP)

A maintenance point (MP) is a demarcation point on a port that implements the CFM functions within an MA. MPs serve as points of contact allowing communication with other devices within the MA. MPs also operate as filters to confine CFM Ethernet frames within the bounds of a domain by dropping frames that do not belong to the correct level. There are two types of MPs: maintenance end-points (MEPs) and maintenance intermediate points (MIPs).
