Requested revision
Standard: | 802.1Q | Clause: | 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

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.

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:
