Management Information Base for IP Version 6:
ICMPv6 Group

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 is one in the series of documents that define various
MIB object groups for IPv6. Specifically, the ICMPv6 group is
defined in this document.

This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the IPv6-based
internets.

This document specifies a MIB module in a manner that is both
compliant to the SNMPv2 SMI, and semantically identical to the peer
SNMPv1 definitions.

1. The SNMPv2 Network Management Framework

The SNMPv2 Network Management Framework presently consists of three
major components. They are:

o the SMI, described in RFC1902 [1] - the mechanisms used for
describing and naming objects for the purpose of management.

o the MIB-II, described in RFC1213/STD 17 [3] - the core set of
managed objects for the Internet suite of protocols.

o RFC1157/STD 15 [4] and RFC1905 [5] which define two versions of the
protocol used for network access to managed objects.

The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.

1.1. Object Definitions

Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1)
defined in the SMI. In particular, each object type is named by an
OBJECT IDENTIFIER, an administratively assigned name. The object type
together with an object instance serves to uniquely identify a
specific instantiation of the object. For human convenience, we often
use a textual string, termed the descriptor, to refer to the object
type.

2. Overview

This document is the one in the series of documents that define
various MIB object groups for IPv6. These groups are the basic unit of
conformance: if the semantics of a group is applicable to an
implementation, then it must implement all objects in that group. For
example, an implementation must implement the TCP group if and only if
it implements the TCP over IPv6 protocol. At minimum, implementations
must implement the IPv6 General group [9] as well as the ICMPv6 group
defined in this document.

This document defines the ICMPv6 group of the IPv6 MIB.

the interface that sources a given
ICMP message which is usually but not
necessarily the output interface for the message."

6. Security Considerations

Certain management information defined in this MIB may be considered
sensitive in some network environments.

Therefore, authentication of received SNMP requests and controlled
access to management information should be employed in such
environments.
