This object classifies the kind of trap being sent: eventAlarm, faultAlarm, clearAlarm, synAlarm, maitainTrap, topDiscovery, or debugTrap. Admins and management systems use it to route or prioritize incoming traps differently, for example treating faultAlarm traps as urgent while topDiscovery traps update topology maps. A trap carrying hwTrapType clearAlarm(2) tells the receiving system that a previously reported fault condition has now been resolved.
