Abstract

   Some IETF protocols make use of Ethernet frame formats and IEEE 802
   parameters.  This document discusses some use of such parameters in
   IETF protocols and specifies IANA considerations for allocation of
   code points under the IANA OUI (Organizationally Unique Identifier).

RFC 5342         IANA & IETF Use of IEEE 802 Parameters   September 2008

1.  Introduction

   Some IETF protocols use Ethernet or other [IEEE] 802 related
   communication frame formats and parameters [IEEE802].  These include
   MAC (Media Access Control) identifiers and protocol identifiers.

   This document specifies IANA considerations for the allocation of
   code points under the IANA OUI.  It also discusses some other IETF
   use of IEEE 802 code points.

   [RFC5226] is incorporated herein except where there are contrary
   provisions in this document.

1.1.  Notations Used in This Document

   This document uses hexadecimal notation.  Each octet (that is, 8-bit
   byte) is represented by two hexadecimal digits giving the value of
   the octet as an unsigned integer.  Successive octets are separated by
   a hyphen.  This document consistently uses IETF bit ordering although
   the physical order of bit transmission within an octet on an IEEE
   [802.3] link is from the lowest order bit to the highest order bit
   (i.e., the reverse of the IETF's ordering).

   In this document:

   "IAB" stands for Individual Address Block, not for Internet
         Architecture Board;

   "MAC" stands for Media Access Control, not for Message Authentication
         Code; and

   "OUI" stands for Organizationally Unique Identifier.

   "**"  indicates exponentiation.  For example, 2**24 is two to the
