Each entry in this table specifies an event class, a grouping of events, as identified by the MTA manufacturer. Any event associated with an event class in this table MUST be specified in the pktcEventTable. The MTA MUST create one entry (index=100) for the event class titled 'generic'. This event class MUST contain all the events that are not contained in any other vendor-specified event classes. A management station SHOULD NOT associate an event with multiple event classes. However, if an event is associated with multiple event classes, the MTA MUST give precedence to the event class with the lowest index. Thus, at a given point in time, only one event class is applicable for an event. The event table (pktcEventTable) provides the event class that affects the event. Whenever an event is generated, the MTA MUST verify the applicable event class entry to take any specified actions. Entries in this table persist across resets and reboots.
