                  SNMPv2 Management Information Base
                for the Internet Protocol using SMIv2

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.

IESG Note:

  The IP, UDP, and TCP MIB modules currently support only IPv4.  These
  three modules use the IpAddress type defined as an OCTET STRING of
  length 4 to represent the IPv4 32-bit internet addresses.  (See RFC
  1902, SMI for SNMPv2.)  They do not support the new 128-bit IPv6
  internet addresses.

1.  Introduction

  A management system contains: several (potentially many) nodes, each
  with a processing entity, termed an agent, which has access to
  management instrumentation; at least one management station; and, a
  management protocol, used to convey management information between
  the agents and management stations.  Operations of the protocol are
  carried out under an administrative framework which defines
  authentication, authorization, access control, and privacy policies.

RFC 2011                   SNMPv2 MIB for IP               November 1996


  Management stations execute management applications which monitor and
  control managed elements.  Managed elements are devices such as
  hosts, routers, terminal servers, etc., which are monitored and
  controlled via access to their management information.

  Management information is viewed as a collection of managed objects,
  residing in a virtual information store, termed the Management
  Information Base (MIB).  Collections of related objects are defined
  in MIB modules.  These modules are written using a subset of OSI's
  Abstract Syntax Notation One (ASN.1) [1], termed the Structure of
  Management Information (SMI) [2].

  This document is the MIB module which defines managed objects for
  managing implementations of the Internet Protocol (IP) [3] and its
  associated Internet Control Message Protocol (ICMP) [4].

  The managed objects in this MIB module were originally defined using
  the SNMPv1 framework as a part of MIB-II [5].  Since then, the
  managed objects related to managing routes in an IP internet were
  updated by RFC 1354 [6].  This document takes the remaining MIB-II
  objects for these protocols, and defines them using the SNMPv2
  framework.

           Setting this object to the value invalid(2) has the effect

           outside the ICMP layer such as the inability of IP to route
           the resultant datagram.  In some implementations there may
           be no types of error which contribute to this counter's
           value."
