Creating Multi-Alarm Behavior Models

Most behavior models employ only one alarm. However, some models require two or more alarms. If a model uses more than one alarm, the alarms generally communicate using the Fire Trigger alarm action. That is, one alarm fires a trigger that causes a transition in a second alarm.

This chapter presents an example of a multi-alarm behavior model (sometimes referred to as multi-tier behavior models), which might serve as an example for your own models.

Section	Description
IfUpDownStatusByType	Presents a multi-alarm model that monitors interface operation status.

   Another good example of a multi-alarm behavior model is the downstream alarm suppression model, NodeStatusDwnStrm, that ships with NerveCenter. For more information, refer to the white paper, Open NerveCenter: Downstream Alarm Suppression.
