IEEE 802.1 Working Group

January 22-26, 2024 Interim Session

Heidelberg, Germany – Mixed Mode

Session Minutes

The Working Group (WG) Chair, Glenn Parsons, presided and had requested that any subgroup Chair in remote attendance have on-site an individual acting on their behalf as needed to help conduct proceedings in “mixed mode”, i.e. with local and remote participants.

The Recording Secretary, Jessy Rouyer, wrote and/or edited the minutes in part based on input from subgroup Chairs and their Secretaries.

Note that, throughout this document, minuted/recorded inputs from any attendee can not/shall not be assumed to represent a position of their employer or affiliated organization. Discussion points captured do not necessarily reflect the views of the presenter, discussion leader or minute taker, and do not imply consensus unless that is explicitly minuted. The content of draft standards is determined by the ballot process; other formal decisions are the subject of Working Group motions.

4 Security Task Group

Between this session and the preceding session, the IEEE 802.1 Security Task Group (Security TG) did not hold electronic meetings.

See section 1 for attendance and affiliation information.

Call to order Jan 24, 2024 at 10:30 CET (Heidelberg time) by Mick Seaman, IEEE 802.1 Security TG Chair, who presided and wrote the minutes.

Agenda items and dispositions:

1. Meeting introduction. The IEEE SA slides on IEEE Patent Policy and IEEE SA Copyright and Participation Policies were provided beforehand as part of “MEETING INTRODUCTION” http://www.ieee802.org/1/files/public/templates/admin-TG-intro-0721-v01.pdf.

The Security TG Chair showed this presentation advising that the following, provided beforehand, applies:

  • IEEEs Patent Policy is described in Clause 6 of the IEEE SA Standards Board Bylaws;
  • Early identification of patent claims which may be essential for the use of standards under development is strongly encouraged;
  • There may be Essential Patent Claims of which IEEE is not aware. Additionally, neither IEEE, the WG, nor the WG Chair can ensure the accuracy or completeness of any assurance or whether any such assurance is, in fact, of a Patent Claim that is essential for the use of the standard under development.
  • IEEE SAs copyright policy is described in Clause 7 of the IEEE SA Standards Board Bylaws and Clause 6.1 of the IEEE SA Standards Board Operations Manual;
  • Any material submitted during standards development, whether verbal, recorded, or in written form, is a Contribution and shall comply with the IEEE SA Copyright Policy.

The Security TG Chair asked participants to record their attendance in IMAT and, if they are unable to do so, to promptly provide their affiliation to the minute taker.

2. Approval of agenda. The Security TG Chair presented the agenda as previously made available in https://1.ieee802.org/january-2024-interim-session-security-tg-agenda/.

Disposition: The agenda was reviewed, discussed, and agreed (informally, none dissenting) as presented.

3. P802.1Qdt Priority-based Flow Control Enhancements

3.1 Draft development. Mick Seaman presented “Priority-based Flow Control – Proposed Clause 36 changes” https://www.ieee802.org/1/files/public/docs2024/dt-seaman-clause-36-proposal-0124-v1.pdf for discussion.

Discussion:

  • This presented document is an update of the document with the same name presented in the Nov 2023 plenary session, minor changes to clauses prior to 36.9 reflect feedback received at that session, 36.9 “PFC headroom measurement protocol” details are new, still lacking details of PFC management (proposed 36.10) including information obtained from DCBX/LLDP exchanges.
  • Walk through from the front of the document.
  • A number of additional points could be made in 36.2.1 “Data center network protocol support”: Incasting is not mentioned, this can be severe (perhaps network topology dependent), with synchronized events resulting in thousands of flows converging at a synchronized time. PFC can provide transient squelching where it takes too long to signal through multiple intermediate systems to the flow sources, and the number of flows to be signaled is too great for individual source signaling. These points are particularly relevant for AI applications. The loss of frames for a single flow can result in the need to recompute for all flows.
  • The suggested headroom measurement protocol accuracy of 8 pause quanta (512 octets) is just a starting point for discussion. In the context of the ~17 kB for 10 Gb/s operation (Annex N of IEEE Std 802.1Q-2022) it may be too tight, always requiring adjustment for interfering frames at turn around.

Disposition: Discussion to be continued.

12:23 CET recess

Call to order Jan 24, 2023 at 13.30 CET by the Security TG Chair, who presided and wrote the minutes.

3.1 Draft development. Mick Seaman presented an initial draft of a Headroom Measurement Protocol state machine https://www.ieee802.org/1/files/public/docs2024/dt-seaman-hrm-state-machine-0124-v00.pdf for discussion.

Discussion:

  • The machine covers both use of the same path for measurement requests and measurement responses and use of separate paths. The former case, which allows requests and responses to be encoded in the same HMPDU, is rather simpler. It might be clearer to separate that case.
  • An alternative way of presenting the information is to use state tables, with states as columns and events as rows, action {Action, Next State} in each table cell. That method has the disadvantage of being sparse in expected operation, with many repeated entries. The machines shown do reduce the number of times common actions are shown, although the method tends toward a flow chart description (“code in boxes”) with the ‘real state’ in variable values, which makes analysis a little more difficult, but is more likely to support faithful implementation.
  • There are some naming inconsistencies in this initial draft, and some names might benefit from being unique in a wider context.

Disposition: Discussion to be continued.

4. A.O.B (Any other business). No other Security TG business was discussed in this meeting.

5. Future meetings. An electronic meeting is expected prior to the Mar 2024 802 plenary session, and the Security TG will meet during that session.

Between this session and the preceding session, YANGsters held electronic meetings whose minutes are incorporated to these session minutes by reference as follows:

See section 1 for attendance and affiliation information.

Call to order Jan 23, 2024, at 17:01 CET by Stephan Kehrer, YANGsters Vice-Chair, who presided over agenda item 1. Scott Mansfield, YANGsters Chair, presided from agenda item 2 to meeting adjournment. Stephan Kehrer, YANGsters Secretary, wrote the minutes.

Agenda items and dispositions:

1. Meeting introduction. The IEEE SA slides on IEEE Patent Policy and IEEE SA Copyright and Participation Policies were provided beforehand as part of “MEETING INTRODUCTION” https://www.ieee802.org/1/files/private/templates/admin-prePAR-intro-0323-v01.pptx.

The YANGsters Vice-Chair announced that the meeting is subject to these Policies as read and displayed at the opening plenary meeting.

The YANGsters Vice-Chair asked participants to record their attendance in IMAT and, if they are unable to do so, to promptly provide their affiliation to the minute taker.

2. Approval of agenda. The YANGsters Chair presented the agenda in https://1.ieee802.org/january-2024-interim-session-yangsters-agenda/.

Disposition: The agenda was reviewed, discussed, and agreed (informally, none dissenting) as presented.

3. Introduction to YANGsters. The YANGsters Chair introduced YANGsters by showing the following:

Disposition: For information.

4. YANGsanity Spreadsheet. The YANGsters Chair presented the spreadsheet available at https://1.ieee802.org/yangsters/yang-sanity/.

  • This spreadsheet provides an overview of all ongoing IEEE 802.1 projects that have YANG in their scope.
  • The most current versions of the YANG modules that are part of IEEE 802.1 documents or projects are available at https://github.com/YangModels/yang/tree/main/standard/ieee.
  • The final reference of any given IEEE 802.1 YANG module is the version that can be found in the corresponding published standard.

Disposition: For information.

5. 802.3 Coordination Update. The YANGsters Chair introduced the topic by showing https://www.ieee802.org/3/2/a/comments/index.html and led the discussion.

  • LLDP YANG and MAC merge YANG are being written in P802.3.2a.
  • Questions on these YANG modules are currently being discussed in IEEE 802.3.

Disposition: For information

6. Updates and actions related to IEEE P802-REVc. The YANGsters Chair introduced the topic.

Disposition: For information.

7. Update related to IEEE Bridge Model and IETF Topology Models. The YANGsters Chair introduced the topic and led the discussion.

Disposition: Agreed (informally, none dissenting) that no further action in YANGsters is required.

8. Integers, Floats, Reals: Number representations in YANG. The YANGsters Chair introduced the topic by showing “Numbers in YANG example” https://www.ieee802.org/1/files/public/docs2024/yangsters-smansfield-numbers-in-yang-0124-v01.pdf and led the discussion.

  • A recommendation presented in this document is to use Decimal64, rather than using a string-based “float”.
  • A second recommendation is that, if a string-based representation is defined, it is recommended to ensure that there is only a single representation, e.g., only allow either “e” or “E” as symbol for the exponent, and not both.

Disposition: For information.

9. MAC Address formatting. The YANGsters Chair introduced the topic.

  • Maintenance item 0312 (https://www.802-1.org/items/423) discusses the issue that the IEEE 802.1 YANG types module currently defines MAC addresses as a regular expression allowing uppercase and lowercase characters.
  • This can create issues with the same MAC address being considered different in different string representations.

Disposition: Agreed (informally, none dissenting) that YANGsters suggest addressing the maintenance item by implementing the previously suggested fix, i.e., deprecating the existing type for MAC addresses and defining a new type that follows the IEEE 802 recommendations on how MAC addresses should be formatted.

10. Discussion on P802.1Qdy. Martin Mittelberger presented the topic by showing “P802.1Qdy – Proposed new YANG model” https://www.ieee802.org/1/files/public/docs2024/dy-mittelberger-rstp-mstp-YANG-0124-v01.pdf and led the discussion.

  • The question was raised whether “presence containers” should be used for the RSTP and MSTP containers in the YANG module or whether using “if-feature” would be preferable.
  • An option is to use presence containers and then use the “if-feature” statement to allow turning the feature on and off.
  • Based on the discussion, the recommendation for P802.1Qdy, and MSTP and RSTP containers, is to use “presence containers”, “when” statements and use the “if-feature” statement on the MSTP container.
  • The use and capabilities of YANG notifications was discussed.

Disposition: For information.

11. Open Discussion. No topics were discussed.

12. Weekly Call Agenda Requests. The YANGsters Chair introduced the topic and led the discussion.

Disposition:

13. Any Other Business. No other YANGsters business was discussed in this meeting.

18:37 CET adjournment
