Description: An entry describes a traffic flow contained by a set of flows.

An alarm group aggregates a standing condition from a set of flows. cfmAlarmFlowSetId uniquely identifies a set of traffic flows.

A device creates a row in the cfmAlarmGroupTable under one of the following circumstances:

- It has configured a new alarm group, and hence a new set of traffic flows.

- It has added a traffic flow to an existing set of flows.

Likewise, a device destroys a row under one of the following circumstances:

- It has destroyed the set of traffic flows.

- It has removed the traffic flow from an existing set of flows.
