         Simple Network Management Protocol (SNMP) Applications

Status of this Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   This document describes five types of Simple Network Management
   Protocol (SNMP) applications which make use of an SNMP engine as
   described in STD 62, RFC 3411.  The types of application described
   are Command Generators, Command Responders, Notification Originators,
   Notification Receivers, and Proxy Forwarders.

   This document also defines Management Information Base (MIB) modules
   for specifying targets of management operations, for notification
   filtering, and for proxy forwarding.  This document obsoletes RFC
   2573.

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
