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 documents should be noted (see www.iso.org/directives).
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.

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 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. A current 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 IEEE Xplore at https://ieeexplore.ieee.org or contact IEEE at the
address listed previously. For more information about the IEEE-SA or IEEE’s standards development process, visit the
IEEE-SA Website at https://standards.ieee.org.
Errata
Errata, if any, for all IEEE standards can be accessed on the IEEE-SA Website at the following URL:
https://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 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.

Introduction
This introduction is not part of IEEE Std 802.1Xck-2018, IEEE Standard for Local and metropolitan area networks—
Port-Based Network Access Control—Amendment 2: YANG Data Model.
This second amendment to IEEE Std 802.1X™-2010 specifies a YANG data model that allows
configuration and status reporting for port-based network access control, in the scenarios described in
Clause 7 of this standard and Clause 11 of IEEE Std 802.1AE™-2018, using the information model
previously specified in this standard.
The first edition of IEEE Std 802.1X was published in 2001. The second edition, IEEE Std 802.1X-2004,
clarified areas related to mutual authentication and the interface between the IEEE 802.1X state machine
and state machines specified by 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, adds authenticated key agreement in support of IEEE 802.1AE™
MAC Security (MACsec) and clarifies and generalizes 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
update the standard to reflect best current practice, insisting, for example, on mutual authentication methods
and using such methods in examples. A greater emphasis is placed on the security of systems accessing the
network, as well as on the security of the network accessed, and some prior provisions, 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) are
described.
Every effort was made to ensure that systems conformant to IEEE Std 802.1X-2010 will 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. IEEE Std 802.1X-2010 includes 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.
IEEE Std 802.1Xbx-2014 is the first amendment to IEEE Std 802.1X-2010. Its MKA extensions make
additional security and manageability capabilities possible based on the changes made by
IEEE Std 802.1AEbw™-2013 that added extended packet numbering Cipher Suites to
IEEE Std 802.1AE-2006. Secure connectivity association (CA) members can temporarily suspend MKA
operation without causing protocol timeouts that would disrupt secure data transfer; thus, in-service control
plane software can be upgraded.

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 documents should be noted (see www.iso.org/directives).
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

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 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

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. A current 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 IEEE Xplore at https://ieeexplore.ieee.org or contact IEEE at the
address listed previously. For more information about the IEEE-SA or IEEE’s standards development process, visit the
IEEE-SA Website at https://standards.ieee.org.
Errata
Errata, if any, for all IEEE standards can be accessed on the IEEE-SA Website at the following URL:
https://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 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.

Introduction
This introduction is not part of IEEE Std 802.1Xck-2018, IEEE Standard for Local and metropolitan area networks—
Port-Based Network Access Control—Amendment 2: YANG Data Model.
This second amendment to IEEE Std 802.1X™-2010 specifies a YANG data model that allows
configuration and status reporting for port-based network access control, in the scenarios described in
Clause 7 of this standard and Clause 11 of IEEE Std 802.1AE™-2018, using the information model
previously specified in this standard.
The first edition of IEEE Std 802.1X was published in 2001. The second edition, IEEE Std 802.1X-2004,
clarified areas related to mutual authentication and the interface between the IEEE 802.1X state machine
and state machines specified by 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, adds authenticated key agreement in support of IEEE 802.1AE™
MAC Security (MACsec) and clarifies and generalizes 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
update the standard to reflect best current practice, insisting, for example, on mutual authentication methods
and using such methods in examples. A greater emphasis is placed on the security of systems accessing the
network, as well as on the security of the network accessed, and some prior provisions, 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) are
described.
Every effort was made to ensure that systems conformant to IEEE Std 802.1X-2010 will 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. IEEE Std 802.1X-2010 includes 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.
IEEE Std 802.1Xbx-2014 is the first amendment to IEEE Std 802.1X-2010. Its MKA extensions make
additional security and manageability capabilities possible based on the changes made by
IEEE Std 802.1AEbw™-2013 that added extended packet numbering Cipher Suites to
IEEE Std 802.1AE-2006. Secure connectivity association (CA) members can temporarily suspend MKA
operation without causing protocol timeouts that would disrupt secure data transfer; thus, in-service control
plane software can be upgraded.
