Abstract

   This memo describes five types of SNMP applications which make use of
   an SNMP engine as described in [RFC2571].  The types of application
   described are Command Generators, Command Responders, Notification
   Originators, Notification Receivers, and Proxy Forwarders.

   This memo also defines MIB modules for specifying targets of
   management operations, for notification filtering, and for proxy
   forwarding.

1.  Overview

   This document describes five types of SNMP applications:

     - Applications which initiate SNMP Read-Class, and/or Write-Class
       requests, called 'command generators.'
     - Applications which respond to SNMP Read-Class, and/or Write-Class
       requests, called 'command responders.'
     - Applications which generate SNMP Notification-Class PDUs, called
       'notification originators.'
