IANA Considerations for Connectivity Fault Management (CFM) Code Points

Abstract

  IEEE 802.1 has specified Connectivity Fault Management (CFM)
  Operations, Administration, and Maintenance (OAM) facilities.  CFM
  messages are structured with an OpCode field and have provision for
  the inclusion of TLV-structured information.  IEEE 802.1 has
  allocated blocks of CFM OpCodes and TLV Types to the IETF.  This
  document specifies the IANA considerations for the assignment of
  values from these blocks.

1.  Introduction

  The IEEE 802.1 Working Group has specified Connectivity Fault
  Management (CFM) [802.1Q] OAM [RFC6291] facilities.  CFM messages are
  structured with an OpCode field and have provision for the inclusion
  of TLV-structured information.

  IEEE 802.1 has allocated the block of 32 CFM OpCodes from 64 through
  95 and the block of 32 CFM TLV Types from 64 through 95 to the IETF
  (see Appendix A).  This document specifies the IANA considerations
  for the assignment of values from these two blocks.

  IEEE 802.1 previously allocated similar blocks of values from 32
  through 63 to ITU-T [Y.1731].

1.1.  Terminology

  Capitalized IANA terms such as "Standards Action" are to be
  interpreted as described in [RFC5226].

2.  IANA Considerations

  IANA has created the "Connectivity Fault Management (CFM) OAM IETF
  Parameters" registry with the following two subregistries:

     Registry Name: CFM OAM IETF OpCodes

     Registration Procedures: Standards Action

     Reference: [802.1Q] [RFC7319]

     Note: This parameter originates with the IEEE 802.1 Working Group
     that has allocated the block of values from 64 to 95 to the IETF.

     Value    Assignment
     =====    ==========
     64-95    Unassigned

RFC 7319         IANA Considerations for CFM Code Points       July 2014


     Registry Name: CFM OAM IETF TLV Types

     Registration Procedures: Standards Action

     Reference: [802.1Q] [RFC7319]

     Note: This parameter originates with the IEEE 802.1 Working Group
     that has allocated the block of values from 64 to 95 to the IETF.

     Value    Assignment
     =====    ==========
     64-95    Unassigned

3.  Security Considerations

  This document is concerned with assignment of values from the blocks
  of IEEE 802.1 CFM OpCodes and TLV Types that the IEEE 802.1 Working
  Group has allocated to the IETF.  It is not directly concerned with
  security.

Appendix A.  IEEE 802.1 WG Liaison

  To:         Jari Arkko, IETF chair

              Donald Eastlake, Erik Nordmark, IETF TRILL WG,
              Eric Gray, IETF/IEEE liaison

  From:       Tony Jeffree, IEEE 802.1 WG Chair

  Date:       Thursday, 06 March 2014

  Reference:  24 September 2013 Liaison from TRILL WG

  After considering the referenced liaison from the TRILL WG, IEEE
  802.1 has voted to approve the allocation of code points from the
  Connectivity Fault Management protocol of IEEE Std 802.1Q(TM)-2011
  for use by IETF.  The expectation of IEEE 802.1 is that these code
  points will be allocated through IANA only on the basis of IETF
  standards actions.  Specifically, the allocation includes:

     + 32 CFM OpCode Field values. Reference IEEE Std 802.1Q-2011

       Clause 21.4.3, Table 21-4. The OpCode Field values 64-95
                                                               10
       are allocated to the IETF.


     + 32 TLV Type Field values. Reference IEEE Std 802.1Q-2011

       Clause 21.5.1.1, Table 21-6. The Type Field values 64-95
                                                               10
       are allocated to the IETF.

     IEEE Std 802.1Q will be revised at some future date to document
     this allocation. In the meantime, the allocation will be recorded
     through the IEEE 802.1 maintenance process.

     Regards,

     Tony Jeffree
     IEEE 802.1 Working Group Chair
