Phoenix, AZ, USA – 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.

It is intended to address this in one of the Maintenance TG meetings held during this interim session.

8. Stating a default value in a description statement. Stephen Haddock, IEEE P802.1AXdz editor, presented “802.1AXdz YANG for Link Aggregation: Editor’s Report: January 2025” https://www.ieee802.org/1/files/public/docs2025/dz-haddock-editors-report-0125-v1.pdf to introduce the topic, and led the discussion.

  • This topic is related to maintenance item 0382 (https://www.802-1.org/items/490), which was discussed.
  • It was also discussed whether it makes sense to put default statements in the descriptions of leaves.
  • It was pointed out that there is no explicit prohibition in IETF RFC 7950 to have a default value for a leaf that is set to be “config false”.
  • Information is provided in “Guidelines for Authors and Reviewers of Documents Containing YANG Data Models” (IETF RFC 8407) on how default statements are handled.
  • YANGsters strongly suggested not to add default values for “config false” leaves, even though it is not prohibited by the YANG specification, as this might cause unintended system behavior in cases where implementations handle this incorrectly.
  • The proposed text provided in the maintenance item is considered to be the best way forward.

Disposition: Agreed (informally, none dissenting) to recommend to the Maintenance TG to accept the proposed text provided in the maintenance item.

9. Interface statistics: The YANGsters Chair presented the topic and led the discussion.

  • It was discussed how to handle the case of a YANG module that includes counters augmenting another YANG module that already contains the same counters, but under a different name. Doing this effectively duplicates the counters in YANG.
  • It was pointed out that this is not a real issue, as long as both of the counters point to the same underlying statistics, since the underlying values are identical in this case.
  • Even though it is not a real problem in such cases, YANGsters recommend not to duplicate counters unnecessarily.

Disposition: For information.

10. Next meeting. YANGsters intend to meet next electronically on Jan 28, 2025.

11. Any Other Business. No other business was discussed during the meeting.

17:27 MT adjournment
