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. This document was drafted in accordance with
the editorial rules of the ISO/IEC Directives, Part 2 (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 https://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),

ISO/IEC/IEEE 8802-1CS was prepared by the LAN/MAN of the IEEE Computer Society (as IEEE
TM
802.1CS -2020) 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.

Important Notices and Disclaimers Concerning IEEE Standards Documents
IEEE Standards documents are made available for use subject to important notices and legal disclaimers.
These notices and disclaimers, or a reference to this page (https://standards.ieee.org/ipr/disclaimers.html),
appear in all standards and may be found under the heading “Important Notices and Disclaimers Concerning
IEEE Standards Documents.”
Notice and Disclaimer of Liability Concerning the Use of IEEE Standards
Documents
IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating
Committees of the IEEE Standards Association (IEEE SA) Standards Board. IEEE develops its standards
through an accredited consensus development process, which brings together volunteers representing varied
viewpoints and interests to achieve the final product. IEEE Standards are documents developed by
volunteers with scientific, academic, and industry-based expertise in technical working groups. Volunteers
are not necessarily members of IEEE or IEEE SA, and participate without compensation from IEEE. While
IEEE administers the process and establishes rules to promote fairness in the consensus development
process, IEEE does not independently evaluate, test, or verify the accuracy of any of the information or the
soundness of any judgments contained in its standards.
IEEE makes no warranties or representations concerning its standards, and expressly disclaims all
warranties, express or implied, concerning this standard, including but not limited to the warranties of
merchantability, fitness for a particular purpose and non-infringement. In addition, IEEE does not warrant or
represent that the use of the material contained in its standards is free from patent infringement. IEEE
standards documents are supplied “AS IS” and “WITH ALL FAULTS.”
Use of an IEEE standard is wholly voluntary. The existence of an IEEE Standard does not imply that there
are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to
the scope of the IEEE standard. Furthermore, the viewpoint expressed at the time a standard is approved and
issued is subject to change brought about through developments in the state of the art and comments
received from users of the standard.
In publishing and making its standards available, IEEE is not suggesting or rendering professional or other
services for, or on behalf of, any person or entity, nor is IEEE undertaking to perform any duty owed by any
other person or entity to another. Any person utilizing any IEEE Standards document, should rely upon his
or her own independent judgment in the exercise of reasonable care in any given circumstances or, as
appropriate, seek the advice of a competent professional in determining the appropriateness of a given IEEE
standard.
IN NO EVENT SHALL IEEE BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,
EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO: THE
NEED TO PROCURE SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS;
OR BUSINESS INTERRUPTION) HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY,
WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR
OTHERWISE) ARISING IN ANY WAY OUT OF THE PUBLICATION, USE OF, OR RELIANCE
UPON ANY STANDARD, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE AND
REGARDLESS OF WHETHER SUCH DAMAGE WAS FORESEEABLE.
Translations
The IEEE consensus development process involves the review of documents in English only. In the event
that an IEEE standard is translated, only the English version published by IEEE is the approved IEEE
standard.

Official statements
A statement, written or oral, that is not processed in accordance with the IEEE SA Standards Board
Operations Manual shall not be considered or inferred to be the official position of IEEE or any of its
committees and shall not be considered to be, nor be relied upon as, a formal position of IEEE. At lectures,
symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall
make it clear that the presenter’s views should be considered the personal views of that individual rather
than the formal position of IEEE, IEEE SA, the Standards Committee, or the Working Group.
Comments on standards
Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of
membership affiliation with IEEE or IEEE SA. However, IEEE does not provide interpretations,
consulting information, or advice pertaining to IEEE Standards documents.
Suggestions for changes in documents should be in the form of a proposed change of text, together with
appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is
important that any responses to comments and questions also receive the concurrence of a balance of
interests. For this reason, IEEE and the members of its Societies and Standards Coordinating Committees
are not able to provide an instant response to comments, or questions except in those cases where the matter
has previously been addressed. For the same reason, IEEE does not respond to interpretation requests. Any
person who would like to participate in evaluating comments or in revisions to an IEEE standard is welcome
to join the relevant IEEE working group. You can indicate interest in a working group using the Interests tab
in the Manage Profile & Interests area of the IEEE SA myProject system. An IEEE Account is needed to
access the application.
Comments on standards should be submitted using the Contact Us form.
Laws and regulations
Users of IEEE Standards documents should consult all applicable laws and regulations. Compliance with the
provisions of any IEEE Standards document does not constitute compliance to any applicable regulatory
requirements. Implementers of the standard are responsible for observing or referring to the applicable
regulatory requirements. IEEE does not, by the publication of its standards, intend to urge action that is not
in compliance with applicable laws, and these documents may not be construed as doing so.
Data privacy
Users of IEEE Standards documents should evaluate the standards for considerations of data privacy and
data ownership in the context of assessing and using the standards in compliance with applicable laws and
regulations.
Copyrights
IEEE draft and approved standards are copyrighted by IEEE under US and international copyright laws.
They are made available by IEEE and are adopted for a wide variety of both public and private uses. These
include both use, by reference, in laws and regulations, and use in private self-regulation, standardization,
and the promotion of engineering practices and methods. By making these documents available for use and
adoption by public authorities and private users, IEEE does not waive any rights in copyright to the
documents.

Photocopies
Subject to payment of the appropriate licensing fees, IEEE will grant users a limited, non-exclusive license
to photocopy portions of any individual standard for company or organizational internal use or individual,
non-commercial use only. To arrange for payment of licensing fees, please contact Copyright Clearance
Center, Customer Service, 222 Rosewood Drive, Danvers, MA 01923 USA; +1 978 750 8400; https://
www.copyright.com/. Permission to photocopy portions of any individual standard for educational
classroom use can also be obtained through the Copyright Clearance Center.
Updating of IEEE Standards documents
Users of IEEE Standards documents should be aware that these documents may be superseded at any time
by the issuance of new editions or may be amended from time to time through the issuance of amendments,
corrigenda, or errata. An official IEEE document at any point in time consists of the current edition of the
document together with any amendments, corrigenda, or errata then in effect.
Every IEEE standard is subjected to review at least every 10 years. When a document is more than 10 years
old and has not undergone a revision process, it is reasonable to conclude that its contents, although still of
some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that
they have the latest edition of any IEEE standard.
In order to determine whether a given document is the current edition and whether it has been amended
through the issuance of amendments, corrigenda, or errata, visit IEEE Xplore or contact IEEE. For more
information about the IEEE SA or IEEE’s standards development process, visit the IEEE SA Website.
Errata
Errata, if any, for all IEEE standards can be accessed on the IEEE SA Website. Search for standard number
and year of approval to access the web page of the published standard. Errata links are located under the
Additional Resources Details section. Errata are also available in IEEE Xplore. Users are encouraged to
periodically check for errata.
Patents
IEEE Standards are developed in compliance with the IEEE SA Patent Policy.
Attention is called to the possibility that implementation of this standard may require use of subject matter
covered by patent rights. By publication of this standard, no position is taken by the IEEE with respect to the
existence or validity of any patent rights in connection therewith. If a patent holder or patent applicant has
filed a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on the IEEE
SA Website at https://standards.ieee.org/about/sasb/patcom/patents.html. Letters of Assurance may indicate
whether the Submitter is willing or unwilling to grant licenses under patent rights without compensation or
under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair
discrimination to applicants desiring to obtain such licenses.
Essential Patent Claims may exist for which a Letter of Assurance has not been received. The IEEE is not
responsible for identifying Essential Patent Claims for which a license may be required, for conducting
inquiries into the legal validity or scope of Patents Claims, or determining whether any licensing terms or
conditions provided in connection with submission of a Letter of Assurance, if any, or in any licensing
agreements are reasonable or non-discriminatory. Users of this standard are expressly advised that
determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their
own responsibility. Further information may be obtained from the IEEE Standards Association.

IMPORTANT NOTICE
IEEE Standards do not guarantee or ensure safety, security, health, or environmental protection, or ensure
against interference with or from other devices or networks. IEEE Standards development activities consider
research and information presented to the standards development group in developing any safety
recommendations. Other information about safety practices, changes in technology or technology
implementation, or impact by peripheral systems also may be pertinent to safety considerations during
implementation of the standard. Implementers and users of IEEE Standards documents are responsible for
determining and complying with all appropriate safety, security, environmental, health, and interference
protection practices and all applicable laws and regulations.
