Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it describes a set of managed objects that are used to
   manage Session Initiation Protocol (SIP) entities, which include User
   Agents, and Proxy, Redirect and Registrar servers.

1.  Introduction

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it describes a set of managed objects that are used to
   manage Session Initiation Protocol (SIP) entities, which include User
   Agents, and Proxy, Redirect and Registrar servers.  The managed
   objects defined in this document are intended to provide basic SIP
   protocol management for SIP entities.  The management of
   application-specific or service-specific SIP configuration is out of
   scope.

2.  Conventions

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

3.  The Internet-Standard Management Framework

   For a detailed overview of the documents that describe the current
   Internet-Standard Management Framework, please refer to section 7 of
   RFC 3410 [RFC3410].

RFC 4780                    SIP MIB Modules                   April 2007

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  MIB objects are generally
   accessed through the Simple Network Management Protocol (SNMP).
   Objects in the MIB are defined using the mechanisms defined in the
   Structure of Management Information (SMI).  This memo specifies a set
   of MIB modules that are compliant to the SMIv2, which is described in
   STD 58, comprised of RFC 2578 [RFC2578], RFC 2579 [RFC2579], and RFC
   2580 [RFC2580].

4.  Overview

   SIP [RFC3261] is an application-layer control (signaling) protocol
   for creating, modifying, and terminating sessions with one or more
   participants.  These sessions include Internet telephone calls,
