Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members
of ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of
document should be noted (see www.iso.org/directives or www.iec.ch/members_experts/refdocs).
IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating
Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards
through a consensus development process, approved by the American National Standards Institute, which
brings together volunteers representing varied viewpoints and interests to achieve the final product.
Volunteers are not necessarily members of the Institute and serve without compensation. While the IEEE
administers the process and establishes rules to promote fairness in the consensus development process, the
IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained in its
standards.
ISO and IEC draw attention to the possibility that the implementation of this document may involve the use of
(a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO and IEC had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent database
available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall not be held responsible for
identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
In the IEC, see www.iec.ch/understanding-standards.
ISO/IEC/IEEE 8802-1Q:2024/Amd 36 was prepared by the LAN/MAN of the IEEE Computer Society (as IEEE
802.1Qcw-2023) and drafted in accordance with its editorial rules. It was adopted, under the “fast-track
procedure” defined in the Partner Standards Development Organization cooperation agreement between ISO
and IEEE, by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 6,
Telecommunications and information exchange between systems.
A list of all parts in the ISO/IEC/IEEE 8802 series can be found on the ISO and IEC websites.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Amendment 36:
YANG Data Models for Scheduled
Traffic, Frame Preemption, and
Per-Stream Filtering and Policing
(This amendment is based on IEEE Std 802.1Q™-2022 as amended by IEEE Std 802.1Qcz-2023.)
NOTE—The editing instructions contained in this amendment define how to merge the material contained therein into
the existing base standard and its amendments to form the comprehensive standard.
The editing instructions are shown in bold italics. Four editing instructions are used: change, delete, insert, and replace.
Change is used to make corrections in existing text or tables. The editing instruction specifies the location of the change
and describes what is being changed by using strikethrough (to remove old material) and underscore (to add new
material). Delete removes existing material. Insert adds new material without disturbing the existing material. Deletions
and insertions may require renumbering. If so, renumbering instructions are given in the editing instruction. Replace is
used to make changes in figures or equations by removing the existing figure or equation and replacing it with a new
one. Editing instructions, change markings, and this note will not be carried over into future editions because the
changes will be incorporated into the base standard.
Notes in text, tables, and figures are given for information only and do not contain requirements needed to implement the standard.
