- <p>
- A <ref table="Monitor"/> attaches to an <ref table="Interface"/> to
- implement 802.1ag Connectivity Fault Management (CFM). CFM allows a
- group of Maintenance Points (MPs) called a Maintenance Association (MA)
- to detect connectivity problems with each other. MPs within a MA should
- have complete and exclusive interconnectivity. This is verified by
- occasionally broadcasting Continuity Check Messages (CCMs) at a
- configurable transmission interval. A <ref table="Monitor"/> is
- responsible for collecting data about other MPs in its MA and
- broadcasting CCMs.

- <group title="Monitor Configuration">
- <column name="mpid">
- A Maintenance Point ID (MPID) uniquely identifies each endpoint within
- a Maintenance Association. The MPID is used to identify this
- <ref table="Monitor"/> to other endpoints in the MA.
- </column>

- <column name="remote_mps">
- A set of <ref table="Maintenance_Points"/> which this
- <ref table="Monitor"/> should have connectivity to. If this
- <ref table="Monitor"/> does not have connectivity to any MPs in this
- set, or has connectivity to any MPs not in this set, a fault is
- signaled.
- </column>
-
- <column name="interval">
- The transmission interval of CCMs in milliseconds. Three missed CCMs
- indicate a connectivity fault. Defaults to 1000ms.
