Enables or disables the alarm anti-flooding (filtering) algorithm. According to such algorithm if the number of event notifications that an alarm receives within a specified time period, namely the observation period, exceeds a given high threshold value, the alarm enters a 'flooding' state. Once an alarm has entered such flooding state, its status is forced to active, according to its related severity, and no further event notifications are processed (neither trapped nor logged). An alarm exits the flooding state when the number of event notifications, received within a subsequent observation period, drops below a given low thresold value. On exiting the flooding state, the trap and log status of an alarm get aligned to the last notified event.
