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

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.

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.

Tony Jeffree
