A table of mappings from notification ids to RMON events.

This table contains one row for each notification type supported by the agent. It provides a way of configuring an RMON eventTable entry to be triggered whenever this notification occurs. This way, each notification can be configured to use a particular community name (which selects a set of entries in the trap destination table to send the notification to), and provides a common point for configuring the action to take when the notification condition occurs.
