Network Working Group D. Haskin Request for Comments: 2466 S. Onishi Category: Standards Track Bay Networks, Inc. December 1998 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. Copyright Notice Copyright (C) The Internet Society (1998). All Rights Reserved. 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. Table of Contents 1.

RFC 2466 IPv6 MIB: ICMPv6 Group December 1998 1. The SNMPv2 Network Management Framework The SNMPv2 Network Management Framework presently consists of three major components. They are: o the SMI, described in RFC 1902 [1] - the mechanisms used for describing and naming objects for the purpose of management. o the MIB-II, described in RFC 1213/STD 17 [3] - the core set of managed objects for the Internet suite of protocols. o RFC 1157/STD 15 [4] and RFC 1905 [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.
