must be exceeded before NTA generates an alarm. Configure this field when you specify
the Direction field as In or In/Out.

must be exceeded before NTA generates an alarm. Configure this field when you specify
the Direction field as Out or In/Out.

be sent again. Options are None, Last 30 minutes, Last 1 hour, and Last 2 hours. The
default setting is Last 30 minutes.
