   SMIv1 during the translation process. However, this loss of machine
   readable information is not considered to change the semantics of the
   MIB.

2.  Introduction

   The SNMP Agent Extensibility Protocol (AgentX) is a protocol used to
   distribute the implementation of an SNMP agent amongst a single
   "master agent" and multiple "subagents". See [17] for details about
   the AgentX protocol.

   The goals of the AgentX MIB are:

   -  List the set of subagent connections that currently have logical
      sessions open with the master agent.

   -  Identify each subagent connection transport address and type.

   -  Identify each subagent session vendor, AgentX protocol version,
      and other characteristics.

   -  Identify the set of MIB objects each session implements, the
      context in which the objects are registered, and the priority of
      the registration.

   -  Determine protocol operational parameters such as the timeout
      interval for responses from a session and the priority at which a
      session registers a particular MIB region.

   -  Allow (but do not require) managers to explicitly close subagent
      sessions with the master agent.

3.  AgentX MIB Overview

   This MIB is organized into four groups.  The agentxGeneral group
   provides information describing the master agent's AgentX support,
   including the protocol version supported.  The agentxConnection group
   provides information describing the current set of connections
   capable of carrying AgentX sessions.  The agentxSession group
   provides information describing the current set of AgentX sessions.
   The agentxRegistration group provides information describing the
   current set of registrations.

   Three tables form the heart of this mib.  These are the connection,
   session, and registration tables.
