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 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 ] CFM OpCode values OpCode value OAM PDU type FM/PM IEEE 802.1 1 CCM FM/PM 3 LBM FM 2 LBR FM 5 LTM FM 4 LTR FM 6 RFM FM 7 SFM FM 0, 8-31, 96-255 Reserved ITU-T SG15 32 GNM FM/PM 32 -1 BNM FM 33 AIS FM 35 LCK FM 37 TST FM 39 Linear APS FM 40 Ring APS FM 41 MCC FM 41-1 EDM FM 43 LMM PM 42 LMR PM 45 1DM PM 47 DMM PM 46 DMR PM 49 EXM FM 48 EXR FM 51 VSM FM 50 VSR FM 52 CSF FM 53 1SL PM 55 SLM PM 54 SLR PM 34, 36, 38, 44, 60-63 Reserved MEF 56 LLR - Latching Loopback FM 57 LLM - Latching Loopback FM 58 SAT - Control Protocol FM/PM 59 SAT - Control Message FM/PM IETF 64 TRILL - Path Trace Reply FM 65 TRILL - Path Trace Message FM 67 TRILL - Multi-destination Tree Verification Reply FM 68 TRILL - Multi-destination Tree Verification Message FM 69-95 Reserved
Impact on existing networks
Uncertainty over which opcodes are assigned by IEEE 802.1Q.
