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 ISO/IEC documents 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents) or
the IEC list of patent declarations received (see http://patents.iec.ch).
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 8802-3 was prepared by the LAN/MAN of the IEEE Computer Society (as IEEE Std
8802-3: 2018) 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.
This third edition cancels and replaces the second edition (ISO/IEC/IEEE 8802-3:2017), which has been
technically revised. It also incorporates the Amendments ISO/IEC/IEEE 8802-3:2017/Amd
