YANGsters Minutes 30 June 2020 (week 27)

YANGsters Weekly Telephone Conference

 

NOTE:  We will be switching to the meeting minute template starting next week.

Agenda for next YANGsters meeting: https://1.ieee802.org/yangsters/yangsters-agenda/

Date/Time:

2020-06-30 (week 27)

10 a.m. – 11 a.m. (Eastern Time)

Participants:

  • Stephan Kehrer (Hirschmann Automation and Control, Inc.)
  • Scott Mansfield (Ericsson)
  • Don Fedyk (LabN Consulting)
  • Glenn Parsons (Ericsson)
  • Mark Ellison (Independent)
  • Paul Congdon (Huawei Technologies Co., Ltd)
  • William Zhao (Siemens AG)

Topics:

  • At the beginning of the meeting the acting YANGsters Chair presented:
  • Agenda bash
  • Update on Hot Issues
    • Active
      • MAC Address Format
        • There was further discussion on this item on the mailing list. The canonical forms used by IEEE and IETF where provided on the list. Additionally, some examples were presented that show inconsistencies with the canonical form within the respective organizations that need to be fixed.
        • Action Item: Contact 802.3 to discussion alignment with ieee802-types yang module.
      • Semantics of read-write in YANG
      • Press Release Discussion
      • IEEE P802f Update
      • YANG Revision Update
      • Update on Tooling Guidance
      • Use of Git workflow document created
      • Status of meta-data in YANG Catalog
        • A form exists for filling in the meta data required for the YANG catalog
        • Action item: fill in this form for the published YANG modules so the meta data can be filled in correctly
      • Splitting functionality out of EVB to support managed objects for ECP in 802.1Q-2018:
        • The topic was brought up during the last maintenance meeting and is intended for discussion during next week’s maintenance call
        • Action item: inform Paul Bottorff that he has an agenda item during next week’s call
  • Continue Maintenance/Guidelines Discussion
  • Any Other Business
    • Next YANGsters meetings:
      • 1 hour on July 7
      • 2 hours on July 16
    • A new item was brought up regarding transmission selection algorithms; currently there is no way to set a TSA for a specific traffic class in the YANG module.
      • There is a proposal to add the possibility to set this via a UInt 8 in the bridge module:

container transmission-selection-algorithm-table {

list transmission-selection-algorithm-mapping {

       key traffic-class;

       leaf traffic-class {

              type dot1qtypes:traffic-class-type;

config false;

              description

                    “The traffic class to which a transmission selection algorithm is assigned to.”;

              reference

                    “Clause 8.6.8 of IEEE Std 802.1Q-2018”;

       }

       leaf transmission-selection-algorithm {

              type uint8;

description

                    “The transmission selection algorithm identifier assigned to the traffic class.”;

              reference

                    “Clause 8.6.8 of IEEE Std 802.1Q-2018”;

      • Another proposal is as follows:

transmission-sel {

    base transmission-selection-algorithm;

    description

      "Indicates the enhanced transmission selection algorithm as

       specified in IEEE Std 802.1Q-2018 Table 8-6. Signalled as value 2

       in the TSA Assignment table field of ETS Configuration and

       Recommendation TLVs";

  }

  identity asynch-traffic-shaping {

    base transmission-selection-algorithm;

    description

      "Indicates the asynchronous transmission selection algorithm as

       specified in IEEE Std 802.1Q-2018 Table 8-6. Signalled as value 3

       in the TSA Assignment table field of ETS Configuration and

       Recommendation TLVs";

  }

  identity vendor-specific {

    base transmission-selection-algorithm;

    description

      "Indicates a vendor specific transmission selection algorithm as

       specified in IEEE Std 802.1Q-2018 Table 8-6. Signalled as value 255

       in the TSA Assignment table field of ETS Configuration and

       Recommendation TLVs";

  }

      • This should be discussed in one of the next YANGsters calls.
    • Action item: the currently published YANG items need to be checked if they include the correct YANG version (1.1) and NMDA compliance statements.
    • No other business.
