	I am obligated to throw in my two bits here.  The original(v1) SNMP specifications were written in terms of manager and managed systems, i.e. NMS and agents.  The new (v3) SNMP specifications, however, use very carefully constructed language which speaks of "command generator applications", "notification receiver applications", etc.  There are a number of implications of this change.  Applications which only generate notifications, such as snmptrap, are now covered by the specs, which they previously were not.  It is also legitimate, some say intended, to perform command generation, command response, notification generation, notifcation reception, and notification response all on the same UDP port!

	To answer the original question in the new terms:  any SNMP engine may receive notifications, provided, of course, that it can receive notifications.  Confusing, but liberating.


	HTH,

Mike
