Requested revision
Standard:802.1QClause:21.4.3
Clause title:OpCode
Rationale for revision
RFC 7319 indicates that IETF has CFM opcodes assigned from IEEE 802.1.   This is not included in IEEE 802.1Q, notably Tables 21-4 and 21-6


   To:         Jari Arkko, IETF chair

   cc:         Stephen J. Trowbridge, ITU-T SG15 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
Proposed text
Modify 802.1Q Table 21-4 and 21-6 to include the IETF allocations.

Consider if IEEE 802.1Q should include the current full list of CFM OpCode values as suggested in the following table:
[Table-1 from http://www.ieee802.org/1/files/public/docs2017/liaison-ITUT-SG15-LS019-CFM_YANG-0417.pdf ]
