Description | An entry describes an alarm group. An alarm group defines an
alarm condition that is raised when a configured number of flows
in a set of flows asserts a configured standing condition.
The figure below illustrates the relationship between an alarm
group, a conditions profile, and a flow set.

A device creates a row in the cfmAlarmGroupTable when it
configures a new alarm group. Likewise, the device destroys a
row when the alarm group ceases to exist. |
