                Textual Conventions for IPv6 Flow Label

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 MIB module defines textual conventions to represent the commonly
   used IPv6 Flow Label.  The intent is that these textual conventions
   (TCs) will be imported and used in MIB modules that would otherwise
   define their own representations.

RFC 3595        Textual Conventions for IPv6 Flow Label   September 2003

1.  Introduction

   Several standards-track MIB modules have defined objects to represent
   an IPv6 Flow Label (sometimes referred to as Flow ID) [RFC2460]
   [FLOWLABEL] and IPv6 Flow Label filters.  Unfortunately the result is
   a set of different definitions for the same piece of management
   information.  This may lead to confusion and unnecessary complexity.

   This document defines a set of textual conventions (TCs) that can and
   should be (re-)used in MIB modules, so that they all represent an
   IPv6 Flow Label in the same way.  In fact, PIB modules can and should
   also use these TCs when they need to represent an IPv6 Flow label.

2.  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].

   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 MIB
   module that is compliant to the SMIv2, which is described in STD 58,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].
