Usage Maintenance Points are entities that exist within an MD/MA and can perform the
CFM/802.1ag functions such as Continuity Checks for fault management. The main
type of MP is a Maintenance End Point (MEP). This type of maintenance point sits
at the edges of a Maintenance Domain but is a member of only one MA within the
Maintenance Domain. Thus an MEP is used at the end of a VLAN segment, or it is
used at the end of a link. MPs live on bridge ports and station ports. On a bridge
port, there are two types.

An Up Maintenance Entity is considered an inward MP. It communicates
across the inside of the bridge to the other side, and this allows it to reach the
outside world. It lives on a bridge port for a given VLAN, but it does not use
this port to send or receive to get to the outside world. Instead, it sends and
receives through the inside of the bridge and communicates to the outside
world through the other VLAN port members. An Up MP cannot be used for
Link Level CFM.
A Down Maintenance Entity is considered an outward MP. It sends and
receives only through its bridge port outwardly to the outside world, and
does not communicate inside the bridge. A Down MP is not subject to
blocking due to Spanning Tree Protocol (STP) or any other protocol trying to
