Subject: Regarding IEEE/IETF coordination draft draft-Wilton-netmod-intf-vlan-yang To: Benoit Claise, Dan Romascanu Dear Benoit, Dan, Thank you for your email (attached below) regarding IEEE/IETF coordination draft draft-Wilton-netmod-intf-vlan-yang In its July 2016 plenary meeting, IEEE 802.1 held detailed discussions of YANG models for 802.1Q and 802.1X, the related interfaces, interface stacks, and the service(s) offered to higher layer entities both in end stations and attached to bridge ports. IEEE 802.1 will continue this work in its September 2016 interim. IEEE 802.1 agrees that progression of draft-Wilton-netmod-intf-vlan-yang as an Informational RFC would be appropriate to meet immediate needs, and values the details included in the document to ensure that the draft does not deviate from 802.1 standards. IEEE 802.1 will continue its work on standard YANG model, appreciates the contribution that other work can make towards that standards goal, and would welcome participation by IETF experts in its face-to- face discussions and teleconferences. IEEE 802.1 ----- From: Benoit Claise [mailto:bclaise@cisco.com] Sent: Thursday, July 21, 2016 2:19 PM To: Romascanu, Dan (Dan); John Messenger; ops-ads@ietf.org; Glenn Parsons Cc: netconf-chairs@ietf.org; Robert Wilton -X (rwilton - Ensoft Ltd at Cisco); Pat Thaler; Eric Gray Subject: Regarding IEEE/IETF coordination draft draft-wilton-netmod-intf-vlan-yang Dear 802.1 WG, In the IETF, we're considering how to progress draft-wilton-netmod-intf-vlan-yang-03 , Sub-interface VLAN YANG Data Models, in order to allow IETF forwarding services to interact with 802.1Q VLAN tagged frames. One option considered is to publish this draft as Informational RFC (as opposed to Proposed Standard), with the understanding that IEEE 802.1 could develop an end station interface model that would considered as the reference standard. Is this a viable solution from the viewpoint of 802.1Q? The latest draft version contains YANG "must" statements to try to constrain the model such that only 802.1 compatible frames result.
