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.

Abstract: Port-based network access control allows a network administrator to restrict the use of
®
IEEE 802 LAN service access points (ports) to secure communication between authenticated and
authorized devices. This standard specifies a common architecture, functional elements, and
protocols that support mutual authentication between the clients of ports attached to the same LAN
and that secure communication between the ports, including the media access method
independent protocols that are used to discover and establish the security associations used by

IEEE 802.1AE MAC Security.

Important Notices and Disclaimers Concerning IEEE Standards Documents
IEEE documents are made available for use subject to important notices and legal disclaimers. These notices and
disclaimers, or a reference to this page, appear in all standards and may be found under the heading “Important Notices
and Disclaimers Concerning IEEE Standards Documents.” They can also be obtained on request from the IEEE or
viewed at https://standards.ieee.org/ipr/disclaimers.html.
Notice and Disclaimer of Liability Concerning the Use of IEEE Standards
Documents
IEEE Standards documents (standards, recommended practices, and guides), both full-use and trial-use, are developed
within IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (“IEEE SA”)
Standards Board. IEEE (“the Institute”) develops its standards through a consensus development process, approved by
the American National Standards Institute (“ANSI”), which brings together volunteers representing varied viewpoints
and interests to achieve the final product. IEEE Standards are documents developed through scientific, academic, and
industry-based technical working groups. Volunteers in IEEE working groups are not necessarily members of the
Institute 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 Standards do not guarantee or ensure safety, security, health, or environmental protection, or ensure against
interference with or from other devices or networks. 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.
IEEE does not warrant or represent the accuracy or content of the material contained in its standards, and expressly
disclaims all warranties (express, implied and statutory) not included in this or any other document relating to the
standard, including, but not limited to, the warranties of: merchantability; fitness for a particular purpose;
non-infringement; and quality, accuracy, effectiveness, currency, or completeness of material. In addition, IEEE
disclaims any and all conditions relating to: results; and workmanlike effort. 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: PROCUREMENT OF
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 should be considered 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, or 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 his or her views should be considered the
personal views of that individual rather than the formal position of IEEE.
Comments on standards
Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membership
affiliation with IEEE. However, IEEE does not provide 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 revisions to an IEEE standard is
welcome to join the relevant IEEE working group.
Comments on standards should be submitted to the following address:
Secretary, IEEE SA Standards Board

Piscataway, NJ 08854 USA
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 imply 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.
Copyrights
IEEE draft and approved standards are copyrighted by IEEE under U.S. 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.

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 ten years. When a document is more than ten 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 the IEEESA Website at
http://ieeexplore.ieee.org/browse/standards/collection/ieee or contact IEEE at the address listed previously. For more
information about the IEEESA or IEEE’s standards development process, visit the IEEESA Website at
http://standards.ieee.org.
Errata
Errata, if any, for all IEEE standards can be accessed on the IEEESA Website at the following URL:
http://standards.ieee.org/findstds/errata/index.html. Users are encouraged to check this URL for errata periodically.
Patents
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 IEEESA Website at
http://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.

ISO/IEC/IEEE 8802-1X:2021(E)
IEEE Std 802.1X-2020
IEEE Standard for Local and Metropolitan Area Networks—Port-Based Network Access Control
Introduction
This introduction is not part of IEEE Std 802.1X™-2020, IEEE Standard for Local and Metropolitan Area
Networks—Port-Based Network Access Control.
This edition of IEEE Std 802.1X™ incorporates IEEE Std 802.1X-2010 and its amendments, IEEE Std
802.1Xbx-2014 and IEEE Std 802.1Xck-2018.
TM
The first edition of IEEE Std 802.1X was published in 2001. The second edition, IEEE Std 802.1X-2004,
clarified mutual authentication and the interface between the IEEE 802.1X state machines and the
Extensible Authentication Protocol (EAP) and by IEEE Std 802.11™ in support of IEEE Std 802.1X.
The third edition, IEEE Std 802.1X-2010, added authenticated key agreement in support of
IEEE Std 802.1AE™ MAC Security (MACsec) and clarified and generalized the relationship between the
common architecture specified for port-based network access control and the functional elements and
protocols that support that architecture as specified in IEEE Std 802.1X, other IEEE 802® standards, and
IETF RFCs. Further changes updated the standard to reflect best current practice, insisting, for example, on
mutual authentication methods and using such methods in examples. A greater emphasis was placed on the
security of systems accessing the network, as well as on the security of the network accessed, with a more
comprehensive treatment of segregating and limiting connectivity to unauthenticated systems. Applications
of port-based network access that use MACsec and/or MACsec Key Agreement protocol (MKA) were
described.
IEEE Std 802.1X-2010 included a number of improvements to the specification of the port access control
protocol (PACP) state machines and their relationship to EAP methods and state machines. Systems
conformant to IEEE Std 802.1X-2020 or IEEE Std 802.1X-2010 should interoperate, without prior
configuration, with implementations conforming to IEEE Std 802.1X-2004 and IEEE Std 802.1X-2001.
However, it is anticipated that claims of conformance with respect to some existing implementations, not
needing to support IEEE Std 802.1AE and already conforming to best current practice as of 2010, will
continue to refer to IEEE Std 802.1X-2004.
The first amendment to IEEE Std 802.1X-2010, IEEE Std 802.1Xbx-2014, extended MKA to further
support and use the extended packet numbering Cipher Suites specified by the IEEE Std
802.1AEbw™-2013. Secure connectivity association (CA) members can temporarily suspend MKA
operation without causing protocol timeouts that would disrupt secure data transfer, thus allowing in-service
control plane software upgrades.
The second amendment to IEEE Std 802.1X-2010, IEEE Std 802.1Xck-2018, specified a YANG data model
for configuration and status reporting, using the information model previously specified in this standard.
