1. Introduction
In situations where it is desirable to centrally manage
authentication, authorization, and accounting (AAA) for IEEE 802
[IEEE-802] networks, deployment of a backend authentication and
accounting server is desirable. In such situations, it is expected
that IEEE 802 authenticators will function as AAA clients.
"IEEE 802.1X Remote Authentication Dial In User Service (RADIUS)
Usage Guidelines" [RFC3580] provides guidelines for the use of the
Remote Authentication Dial-In User Service (RADIUS) within networks
utilizing IEEE 802 local area networks. This document defines
additional attributes suitable for usage by IEEE 802 authenticators
acting as AAA clients.
Aboba, et al. Standards Track [Page 3]
RFC 7268 RADIUS Attributes for IEEE 802 July 2014
1.1. Terminology
This document uses the following terms:
Access Point (AP)
A Station that provides access to the distribution services via
the wireless medium for associated Stations.
Association
The service used to establish Access Point/Station mapping and
enable Station invocation of the distribution system services.
Authenticator
An entity that requires authentication from the Supplicant. The
authenticator may be connected to the Supplicant at the other end
of a point-to-point LAN segment or wireless link.
Authentication Server
An entity that provides an authentication service to an
authenticator. This service verifies the claim of identity made
by the Supplicant using the credentials provided by the Supplicant
Station (STA)
Any device that contains an IEEE 802.11 conformant Medium Access
Control (MAC) and Physical Layer (PHY) interface to the wireless
medium (WM).
Supplicant
An entity that is being authenticated by an authenticator. The
Supplicant may be connected to the authenticator at one end of a
point-to-point LAN segment or 802.11 wireless link.
1.2. Requirements Language
In this document, several words are used to signify the requirements
of the specification. The key words "MUST", "MUST NOT", "REQUIRED",
"SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY",
and "OPTIONAL" in this document are to be interpreted as described in
[RFC2119].

RFC 7268 RADIUS Attributes for IEEE 802 July 2014
2. RADIUS Attributes
2.1. Allowed-Called-Station-Id
Description
The Allowed-Called-Station-Id Attribute allows the RADIUS server
to specify the authenticator MAC addresses and/or networks to
which the user is allowed to connect. One or more Allowed-Called-
Station-Id Attributes MAY be included in an Access-Accept, CoA-
Request, or Accounting-Request packet.
The Allowed-Called-Station-Id Attribute can be useful in
situations where pre-authentication is supported (e.g., IEEE
802.11 pre-authentication). In these scenarios, a Called-Station-
Id Attribute typically will not be included within the Access-
Request so that the RADIUS server will not know the network that
the user is attempting to access. The Allowed-Called-Station-Id
enables the RADIUS server to restrict the networks and attachment
points to which the user can subsequently connect.
A summary of the Allowed-Called-Station-Id Attribute format is
shown below. The fields are transmitted from left to right.
0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

| Type | Length | String...
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
Type
174
Length
>=3
String
The String field is one or more octets, specifying a Called-
Station-Id that the user MAY connect to; if the Called-Station-Id
that the user connects to does not match one of the Allowed-
Called-Station-Id Attributes, the Network Access Server (NAS) MUST
NOT permit the user to access the network.
Aboba, et al. Standards Track [Page 5]
RFC 7268 RADIUS Attributes for IEEE 802 July 2014
In the case of IEEE 802, the Allowed-Called-Station-Id Attribute
is used to store the Medium Access Control (MAC) address,
represented as an uppercase ASCII character string in Canonical
format and with octet values separated by a "-", for example,
"00-10-A4-23-19-C0". Where restrictions on both the network and
authenticator MAC address usage are intended, the network name
MUST be appended to the authenticator MAC address, separated from
the MAC address with a ":", for example, "00-10-A4-23-19-C0:AP1".
Where no MAC address restriction is intended, the MAC address
field MUST be omitted, but ":" and the network name field MUST be
included, for example, ":AP1".
Within IEEE 802.11 [IEEE-802.11], the Service Set Identifier
(SSID) constitutes the network name; within IEEE 802.1X
[IEEE-802.1X] wired networks, the Network-Id Name (NID-Name)
constitutes the network name. Since a NID-Name can be up to 253
octets in length, when used with [IEEE-802.1X] wired networks,
there may not be sufficient room within the Allowed-Called-
Station-Id Attribute to include both a MAC address and a network
name. However, as the Allowed-Called-Station-Id Attribute is
expected to be used largely in wireless access scenarios, this
restriction is not considered serious.
2.2. EAP-Key-Name
Description
The EAP-Key-Name Attribute, defined in "Diameter Extensible
Authentication Protocol (EAP) Application" [RFC4072], contains the
EAP Session-Id, as described in "Extensible Authentication
Protocol (EAP) Key Management Framework" [RFC5247]. Exactly how
this attribute is used depends on the link layer in question.
It should be noted that not all link layers use this name. An
EAP-Key-Name Attribute MAY be included within Access-Request,
Access-Accept, and CoA-Request packets. A summary of the EAP-Key-
Name Attribute format is shown below. The fields are transmitted
from left to right.
0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

Aboba, et al. Standards Track [Page 6]
RFC 7268 RADIUS Attributes for IEEE 802 July 2014
Length
>=3
String
The String field is one or more octets, containing the EAP
Session-Id, as defined in "Extensible Authentication Protocol
(EAP) Key Management Framework" [RFC5247]. Since the NAS operates
as a pass-through in EAP, it cannot know the EAP Session-Id before
receiving it from the RADIUS server. As a result, an EAP-Key-Name
Attribute sent in an Access-Request MUST only contain a single NUL
character. A RADIUS server receiving an Access-Request with an
EAP-Key-Name Attribute containing anything other than a single NUL
character MUST silently discard the attribute. In addition, the
RADIUS server SHOULD include this attribute in an Access-Accept or
CoA-Request only if an EAP-Key-Name Attribute was present in the
Access-Request. Since a NAS will typically only include an EAP-
Key-Name Attribute in an Access-Request in situations where the
attribute is required to provision service, if an EAP-Key-Name
Attribute is included in an Access-Request but is not present in
the Access-Accept, the NAS SHOULD treat the Access-Accept as
though it were an Access-Reject. If an EAP-Key-Name Attribute was
not present in the Access-Request but is included in the Access-
Accept, then the NAS SHOULD silently discard the EAP-Key-Name
Attribute. As noted in Section 6.2.2 of [IEEE-802.1X], the
Connectivity Association Key Name (CKN) is derived from the EAP
Session-Id, and, as described in Section 9.3.3 of [IEEE-802.1X],
the CKN is subsequently used in the derivation of the Key
Encrypting Key (KEK) and the Integrity Check Value Key (ICK),
which protect the Secure Association Keys (SAKs) utilized by Media
Access Control Security (MACsec). As a result, for the NAS to
acquire information needed in the MACsec Key Agreement (MKA)
exchange, it needs to include the EAP-Key-Name Attribute in the
Access-Request and receive it from the RADIUS server in the
Access-Accept.
2.3. EAP-Peer-Id
Description
The EAP-Peer-Id Attribute contains a Peer-Id generated by the EAP
method. Exactly how this name is used depends on the link layer
in question. See [RFC5247] for more discussion. The EAP-Peer-Id
Attribute MAY be included in Access-Request, Access-Accept, and
Accounting-Request packets. More than one EAP-Peer-Id Attribute
MUST NOT be included in an Access-Request; one or more EAP-Peer-Id
Attributes MAY be included in an Access-Accept.
Aboba, et al. Standards Track [Page 7]
RFC 7268 RADIUS Attributes for IEEE 802 July 2014
It should be noted that not all link layers use this name, and
existing EAP method implementations do not generate it. Since the
NAS operates as a pass-through in EAP [RFC3748], it cannot know
the EAP-Peer-Id before receiving it from the RADIUS server. As a
result, an EAP-Peer-Id Attribute sent in an Access-Request MUST
only contain a single NUL character. A home RADIUS server
receiving an Access-Request with an EAP-Peer-Id Attribute
containing anything other than a single NUL character MUST
silently discard the attribute. In addition, the home RADIUS
server SHOULD include one or more EAP-Peer-Id Attributes in an
Access-Accept only if an EAP-Peer-Id Attribute was present in the
Access-Request. If a NAS receives EAP-Peer-Id Attribute(s) in an
Access-Accept without having included one in an Access-Request,
the NAS SHOULD silently discard the attribute(s). A summary of
the EAP-Peer-Id Attribute format is shown below. The fields are
transmitted from left to right.

String
The String field is one or more octets, containing an EAP Peer-Id
exported by the EAP method. For details, see Appendix A of
[RFC5247]. A robust implementation SHOULD support the field as
undistinguished octets. Only a single EAP Peer-Id may be included
per attribute.
2.4. EAP-Server-Id
Description
The EAP-Server-Id Attribute contains a Server-Id generated by the
EAP method. Exactly how this name is used depends on the link
layer in question. See [RFC5247] for more discussion. The EAP-
Server-Id Attribute is only allowed in Access-Request, Access-
Accept, and Accounting-Request packets. More than one EAP-Server-
Aboba, et al. Standards Track [Page 8]
RFC 7268 RADIUS Attributes for IEEE 802 July 2014
Id Attribute MUST NOT be included in an Access-Request; one or
more EAP-Server-Id Attributes MAY be included in an Access-Accept.
It should be noted that not all link layers use this name, and
existing EAP method implementations do not generate it. Since the
NAS operates as a pass-through in EAP [RFC3748], it cannot know
the EAP-Server-Id before receiving it from the RADIUS server. As
a result, an EAP-Server-Id Attribute sent in an Access-Request
MUST contain only a single NUL character. A home RADIUS server
receiving an Access-Request with an EAP-Server-Id Attribute
containing anything other than a single NUL character MUST
silently discard the attribute. In addition, the home RADIUS
server SHOULD include this attribute in an Access-Accept only if
an EAP-Server-Id Attribute was present in the Access-Request. A
summary of the EAP-Server-Id Attribute format is shown below. The
fields are transmitted from left to right.

String
The String field is one or more octets, containing an EAP Server-
Id exported by the EAP method. For details, see Appendix A of
[RFC5247]. A robust implementation SHOULD support the field as
undistinguished octets.
2.5. Mobility-Domain-Id
Description
A single Mobility-Domain-Id Attribute MAY be included in an
Access-Request or Accounting-Request in order to enable the NAS to
provide the RADIUS server with the Mobility Domain Identifier
(MDID), defined in Section 8.4.2.49 of [IEEE-802.11]. A summary
of the Mobility-Domain-Id Attribute format is shown below. The
fields are transmitted from left to right.

The Value field is four octets, containing a 32-bit unsigned
integer. The two most significant octets MUST be set to zero by
the sender and are ignored by the receiver; the two least
significant octets contain the Mobility Domain Identifier (MDID)
defined in Section 8.4.2.49 of [IEEE-802.11].

2.6. Preauth-Timeout
Description
This attribute sets the maximum number of seconds that pre-
authentication state is required to be kept by the NAS without
being utilized within a user session. For example, when
[IEEE-802.11] pre-authentication is used, if a user has not
attempted to utilize the Pairwise Master Key (PMK) derived as a
result of pre-authentication within the time specified by the
Preauth-Timeout Attribute, the PMK MAY be discarded by the Access
Point. However, once the session is underway, the Preauth-Timeout
Attribute has no bearing on the maximum session time for the user
or the maximum time during which key state may be kept prior to
re-authentication. This is determined by the Session-Timeout
Attribute, if present.
Aboba, et al. Standards Track [Page 10]
RFC 7268 RADIUS Attributes for IEEE 802 July 2014
A single Preauth-Timeout Attribute MAY be included within an
Access-Accept or CoA-Request packet. A summary of the Preauth-
Timeout Attribute format is shown below. The fields are
transmitted from left to right.

Value
The field is 4 octets, containing a 32-bit unsigned integer
encoding the maximum time in seconds that pre-authentication state
should be retained by the NAS.
2.7. Network-Id-Name
Description
The Network-Id-Name Attribute is utilized by implementations of
IEEE-802.1X [IEEE-802.1X] to specify the name of a Network-Id
(NID-Name).
Unlike the IEEE 802.11 SSID (which is a maximum of 32 octets in
length), the NID-Name may be up to 253 octets in length.
Consequently, if the MAC address is included within the Called-
Station-Id Attribute, it is possible that there will not be enough
remaining space to encode the NID-Name as well. Therefore, when
used with IEEE 802.1X [IEEE-802.1X], the Called-Station-Id
Attribute SHOULD contain only the MAC address, with the Network-
Id-Name Attribute used to transmit the NID-Name. The Network-Id-
Name Attribute MUST NOT be used to encode the IEEE 802.11 SSID; as
noted in [RFC3580], the Called-Station-Id Attribute is used for
this purpose.
Aboba, et al. Standards Track [Page 11]
RFC 7268 RADIUS Attributes for IEEE 802 July 2014
Zero or one Network-Id-Name Attribute is permitted within an
Access-Request, Access-Challenge, Access-Accept or Accounting-
Request packet. When included within an Access-Request packet,
the Network-Id-Name Attribute represents a hint of the NID-Name to
which the Supplicant should be granted access. When included
within an Access-Accept packet, the Network-Id-Name Attribute
represents the NID-Name to which the Supplicant is to be granted
access. When included within an Accounting-Request packet, the
Network-Id-Name Attribute represents the NID-Name to which the
Supplicant has been granted access.
A summary of the Network-Id-Name Attribute format is shown below.
The fields are transmitted from left to right.

String
The String field is one or more octets, containing a NID-Name.
For details, see [IEEE-802.1X]. A robust implementation SHOULD
support the field as undistinguished octets.
2.8. EAPoL-Announcement
Description
The EAPoL-Announcement Attribute contains EAPoL-Announcement Type-
Length-Value (TLV) tuples defined within Table 11-8 of IEEE-802.1X
[IEEE-802.1X]. The acronym "EAPoL" stands for Extensible
Authentication Protocol over Local Area Network.
Zero or more EAPoL-Announcement Attributes are permitted within an
Access-Request, Access-Accept, Access-Challenge, Access-Reject,
Accounting-Request, CoA-Request, or Disconnect-Request packet.
Aboba, et al. Standards Track [Page 12]
RFC 7268 RADIUS Attributes for IEEE 802 July 2014
When included within an Access-Request packet, EAPoL-Announcement
Attributes contain EAPoL-Announcement TLVs that the user sent in
an EAPoL-Announcement. When included within an Access-Accept,
Access-Challenge, Access-Reject, CoA-Request or Disconnect-Request
packet, EAPoL-Announcement Attributes contain EAPoL-Announcement
TLVs that the NAS is to send to the user in a unicast EAPoL-
Announcement. When sent within an Accounting-Request packet,
EAPoL-Announcement Attributes contain EAPoL-Announcement TLVs that
the NAS has most recently sent to the user in a unicast EAPoL-
Announcement.
A summary of the EAPoL-Announcement Attribute format is shown
below. The fields are transmitted from left to right.
0 1 2 3

String
The String field is one or more octets, containing EAPoL-
Announcement TLVs in the format defined in Figure 11-8 of Section
11.12 of [IEEE-802.1X]. Any EAPoL-Announcement TLV Type MAY be
included within an EAPoL-Announcement Attribute, including
Organizationally Specific TLVs. If multiple EAPoL-Announcement
Attributes are present in a packet, their String fields MUST be
concatenated before being parsed for EAPoL-Announcement TLVs; this
allows EAPoL-Announcement TLVs longer than 253 octets to be
transported by RADIUS. Similarly, EAPoL-Announcement TLVs larger
than 253 octets MUST be fragmented between multiple EAPoL-
Announcement Attributes.

RFC 7268 RADIUS Attributes for IEEE 802 July 2014
2.9. WLAN-HESSID
Description
The WLAN-HESSID Attribute contains a MAC address that identifies
the Homogenous Extended Service Set. The HESSID is a globally
unique identifier that, in conjunction with the SSID, encoded
within the Called-Station-Id Attribute as described in [RFC3580],
may be used to provide network identification for a subscription
service provider network (SSPN), as described in Section 8.4.2.94
of [IEEE-802.11]. Zero or one WLAN-HESSID Attribute is permitted
within an Access-Request or Accounting-Request packet.
A summary of the WLAN-HESSID Attribute format is shown below. The
fields are transmitted from left to right.

2.10. WLAN-Venue-Info
Description
The WLAN-Venue-Info Attribute identifies the category of venue
hosting the WLAN, as defined in Section 8.4.1.34 of [IEEE-802.11].
Zero or more WLAN-Venue-Info Attributes may be included in an
Access-Request or Accounting-Request.

2.11. WLAN-Venue-Language
Description
The WLAN-Venue-Language Attribute is a string encoded by
ISO-14962-1997 [ISO-14962-1997] that defines the language used in
the WLAN-Venue-Name Attribute. Zero or more WLAN-Venue-Language
Attributes may be included in an Access-Request or Accounting-
Request, and each one indicates the language of the WLAN-Venue-
Name Attribute that follows it.
A summary of the WLAN-Venue-Language Attribute format is shown
below. The fields are transmitted from left to right.

2.13. WLAN-Reason-Code
Description
The WLAN-Reason-Code Attribute contains information on the reason
why a Station has been refused network access and has been
disassociated or de-authenticated. This can occur due to policy
or for reasons related to the user's subscription.
A WLAN-Reason-Code Attribute MAY be included within an Access-
Reject or Disconnect-Request packet, as well as within an
Accounting-Request packet. Upon receipt of an Access-Reject or
Disconnect-Request packet containing a WLAN-Reason-Code Attribute,
the WLAN-Reason-Code value is copied by the Access Point into the
Reason Code field of a Disassociation or Deauthentication frame
(see Clauses 8.3.3.4 and 8.3.3.12, respectively, in
[IEEE-802.11]), which is subsequently transmitted to the Station.
A summary of the WLAN-Reason-Code Attribute format is shown below.
The fields are transmitted from left to right.

RFC 7268 RADIUS Attributes for IEEE 802 July 2014
The following table defines the above table entries.
0 This attribute MUST NOT be present in packet.
0+ Zero or more instances of this attribute MAY be present in the
packet.
0-1 Zero or one instance of this attribute MAY be present in the
packet.
4. IANA Considerations
This document uses the RADIUS [RFC2865] namespace; see
<http://www.iana.org/assignments/radius-types>. Per this
specification, RADIUS attribute types have been assigned for the
following attributes:
Attribute Type
========= ====
Allowed-Called-Station-Id 174
EAP-Peer-Id 175
EAP-Server-Id 176
Mobility-Domain-Id 177
Preauth-Timeout 178
Network-Id-Name 179
EAPoL-Announcement 180
WLAN-HESSID 181
WLAN-Venue-Info 182
WLAN-Venue-Language 183
WLAN-Venue-Name 184
WLAN-Reason-Code 185
WLAN-Pairwise-Cipher 186
WLAN-Group-Cipher 187
WLAN-AKM-Suite 188
WLAN-Group-Mgmt-Cipher 189
WLAN-RF-Band 190
Since this specification relies entirely on values assigned by IEEE
802, no registries are established for maintenance by the IANA.
5. Security Considerations
Since this document describes the use of RADIUS for purposes of
authentication, authorization, and accounting in IEEE 802 networks,
it is vulnerable to all of the threats that are present in other
RADIUS applications. For a discussion of these threats, see
[RFC2607], [RFC2865], [RFC3162], [RFC3579], [RFC3580], and [RFC5176].
In particular, when RADIUS traffic is sent in the clear, the
attributes defined in this document can be obtained by an attacker
Aboba, et al. Standards Track [Page 25]
RFC 7268 RADIUS Attributes for IEEE 802 July 2014
snooping the exchange between the RADIUS client and server. As a
result, RADIUS confidentiality is desirable; for a review of RADIUS
security and crypto-agility requirements, see [RFC6421].
While it is possible for a RADIUS server to make decisions on whether
to accept or reject an Access-Request based on the values of the
WLAN-Pairwise-Cipher, WLAN-Group-Cipher, WLAN-AKM-Suite, WLAN-Group-
Mgmt-Cipher, and WLAN-RF-Band Attributes, the value of doing this is
limited. In general, an Access-Reject should not be necessary,
except where Access Points and Stations are misconfigured so as to
enable connections to be made with unacceptable values. Rather than
rejecting access on an ongoing basis, users would be better served by
fixing the misconfiguration.
Where access does need to be rejected, the user should be provided
with an indication of why the problem has occurred, or else they are
likely to become frustrated. For example, if the values of the WLAN-
Pairwise-Cipher, WLAN-Group-Cipher, WLAN-AKM-Suite, or WLAN-Group-
Mgmt-Cipher Attributes included in the Access-Request are not
acceptable to the RADIUS server, then a WLAN-Reason-Code Attribute
with a value of 29 (Requested service rejected because of service
provider ciphersuite or AKM requirement) SHOULD be returned in the
Access-Reject. Similarly, if the value of the WLAN-RF-Band Attribute
included in the Access-Request is not acceptable to the RADIUS
server, then a WLAN-Reason-Code Attribute with a value of 11
(Disassociated because the information in the Supported Channels
element is unacceptable) SHOULD be returned in the Access-Reject.
