=======================================================



Some background information:

RFC 3575 Section 2.1 states the following:

Certain attributes (for example, NAS-Port-Type) in RADIUS define a
list of values to correspond with various meanings. There can be 4
billion (2^32) values for each attribute. Additional values can be
allocated by the Designated Expert. The exception to this policy is
the Service-Type attribute (6), whose values define new modes of
operation for RADIUS. Values 1-16 of the Service-Type attribute have
been allocated. Allocation of new Service-Type values are by IETF
Consensus. The intention is that any allocation will be accompanied
by a published RFC.

Note that the Tunnel-Type and Tunnel-Medium-Type attributes are not called out as an exception, only Service-Type. If the intent was to exempt RFC 2868, those attributes would have been included as exceptions but they are not.

Therefore, it looks to me like the omission of RFC 2868 in the Updates: header is an errata.

In other words:

The discussion, as I understand it, is about "IETF consensus" versus "Designated Expert"

From RFC 2868

6.1. Tunnel-Type Attribute Values

Values 1-12 of the Tunnel-Type Attribute are defined in Section 5.1;
the remaining values are available for assignment by the IANA with
IETF Consensus [16].

6.2. Tunnel-Medium-Type Attribute Values

Values 1-15 of the Tunnel-Medium-Type Attribute are defined in
Section 5.2; the remaining values are available for assignment by the
IANA with IETF Consensus [16].

From RFC 3575

Certain attributes (for example, NAS-Port-Type) in RADIUS define a
list of values to correspond with various meanings. There can be 4
billion (2^32) values for each attribute. Additional values can be
allocated by the Designated Expert. The exception to this policy is
the Service-Type attribute (6), whose values define new modes of
operation for RADIUS.

So Tunnel-Type and Tunnel-Medium-Type are "IETF consensus" or "Designated Expert"?

From the IETF 80 meeting minutes, https://www.ietf.org/proceedings/80/minutes/radext.txt:

2. IANA issues
A. How to allocate tunnel params? In RFC 3575 (RFC2868 conflicts as 3575 assigns based on expert review but didn’t update 2868). Omission of RFC 2868 could be an errata; this is basically a request for metadata.
- Asks Dan for comment: was looking for input from the working group before proceeding.
- Alan thought it was an errata.
- Stefan states no opinion.
- Klaas also states no opinion.
- Nancy asks for further understanding. Bernard clarifies: RFC 2868 states “standards action” and 3575 is more lenient in saying just expert review.
- Now Dan remembers: when there’s conflicts such as this, 2 solutions: take the stricter or take the latest. But if it’s the latest, then it needs to be clearer. Believes in this case, explicit clarification is justified since 3575 is more recent and the request is justified. But need IESG perspective review by WG.
- Bernard suggests to get a sense of this group and then take it to the mailgroup.
Asks: proposal is to accept and verify the errata and update 3575 to include 2868.
In favor: 10, non oppose. Given consensus, will take to the mail list.
Category: Standard Track IANA Considerations for RADIUS (Remote Authentication Dial In User Service) Status of this Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (2003). All Rights Reserved. Abstract This document describes the IANA considerations for the Remote Authentication Dial In User Service (RADIUS). This document updates RFC 2865. 1. Introduction This document provides guidance to the Internet Assigned Numbers Authority (IANA) regarding registration of values related to the Remote Authentication Dial In User Service (RADIUS), defined in [RFC2865], in accordance with BCP 26, [RFC2434]. It also reserves Packet Type Codes that are or have been in use on the Internet. 1.1. Specification of Requirements In this document, several words are used to signify the requirements of the specification. These words are often capitalized. 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]. 1.2. Terminology The following terms are used here with the meanings defined in BCP 26: "name space", "assigned value", "registration". The following policies are used here with the meanings defined in BCP 26: "Private Use", "First Come First Served", "Expert Review", "Specification Required", "IESG Approval", "IETF Consensus", "Standards Action". 2. IANA Considerations There are three name spaces in RADIUS that require registration: Packet Type Codes, Attribute Types, and Attribute Values (for certain Attributes). This document creates no new IANA registries, since a RADIUS registry was created by [RFC2865]. RADIUS is not intended as a general-purpose protocol, and allocations SHOULD NOT be made for purposes unrelated to Authentication, Authorization or Accounting. 2.1. Recommended Registration Policies For registration requests where a Designated Expert should be consulted, the responsible IESG area director should appoint the Designated Expert. The intention is that any allocation will be accompanied by a published RFC. However, the Designated Expert can approve allocations once it seems clear that an RFC will be published, allowing for the allocation of values prior to the document being approved for publication as an RFC. The Designated Expert will post a request to the AAA WG mailing list (or a successor designated by the Area Director) for comment and review, including an Internet-Draft. Before a period of 30 days has passed, the Designated Expert will either approve or deny the registration request, publish a notice of the decision to the AAA WG mailing list or its successor, and inform IANA of its decision. A denial notice must be justified by an explanation and, in the cases where it is possible, concrete suggestions on how the request can be modified so as to become acceptable. Packet Type Codes have a range from 1 to 253. RADIUS Type Codes 1-5 and 11-13 were allocated in [RFC2865], while Type Codes 40-45, 250-253 are allocated by this document. Type Codes 250-253 are allocated for Experimental Uses, and 254-255 are reserved. Packet Type Codes 6-10, 12-13, 21-34, 50-51 have no meaning defined by an IETF RFC, but are reserved until a specification is provided for them. This is being done to avoid interoperability problems with software that implements non-standard RADIUS extensions that are or have been in use on the Internet. Because a new Packet Type has considerable impact on interoperability, a new Packet Type Code requires IESG Approval. The intention is that any allocation will be accompanied by a published RFC. Type Codes 52-249 should be allocated first; when these are exhausted, Type Codes 14-20, 35-39, 46-49 may be allocated. For a list of Type Codes, see Appendix A. Attribute Types have a range from 1 to 255, and are the scarcest resource in RADIUS, thus must be allocated with care. Attributes 1-53,55,60-88,90-91,94-100 have been allocated, with 17 and 21 available for re-use. Attributes 17, 21, 54, 56-59, 89, 101-191 may be allocated by IETF Consensus. It is recommended that attributes 17 and 21 be used only after all others are exhausted. Note that RADIUS defines a mechanism for Vendor-Specific extensions (Attribute 26) for functions specific only to one vendor's implementation of RADIUS, where no interoperability is deemed useful. For functions specific only to one vendor's implementation of RADIUS, the use of that should be encouraged instead of the allocation of global attribute types. As noted in [RFC2865]: Attribute Type Values 192-223 are reserved for experimental use, values 224-240 are reserved for implementation-specific use, and values 241-255 are reserved and should not be used. Therefore Attribute Type values 192-240 are considered Private Use, and values 241-255 require Standards Action. Certain attributes (for example, NAS-Port-Type) in RADIUS define a list of values to correspond with various meanings. There can be 4 billion (2^32) values for each attribute. Additional values can be allocated by the Designated Expert. The exception to this policy is the Service-Type attribute (6), whose values define new modes of operation for RADIUS. Values 1-16 of the Service-Type attribute have been allocated. Allocation of new Service-Type values are by IETF Consensus. The intention is that any allocation will be accompanied by a published RFC. 3. References 3.1.

Security Considerations The security considerations detailed in [RFC2434] are generally applicable to this document. Security considerations relating to the RADIUS protocol are discussed in [RFC2607], [RFC2865], [RFC3162], [DynAuth], and [RFC2869bis]. Appendix A - RADIUS Packet Types A list of RADIUS Packet Type Codes is given below. This document instructs IANA to list them in the registry of Packet Type Codes. Note that Type Codes 40-45, defined in [DynAuth], are being formally allocated here. Codes 40-45 were listed in [RFC2882] and have been implemented and used. Given their current widespread usage, these assignments are not reclaimable in practice. # Message Reference ---- ------------------------- --------- 1 Access-Request [RFC2865] 2 Access-Accept [RFC2865] 3 Access-Reject [RFC2865] 4 Accounting-Request [RFC2865] 5 Accounting-Response [RFC2865] 6 Accounting-Status [RFC2882] (now Interim Accounting) 7 Password-Request [RFC2882] 8 Password-Ack [RFC2882] 9 Password-Reject [RFC2882] 10 Accounting-Message [RFC2882] 11 Access-Challenge [RFC2865] 12 Status-Server (experimental) [RFC2865] 13 Status-Client (experimental) [RFC2865] 21 Resource-Free-Request [RFC2882] 22 Resource-Free-Response [RFC2882] 23 Resource-Query-Request [RFC2882] 24 Resource-Query-Response [RFC2882] 25 Alternate-Resource- Reclaim-Request [RFC2882] 26 NAS-Reboot-Request [RFC2882] 27 NAS-Reboot-Response [RFC2882] 28 Reserved 29 Next-Passcode [RFC2882] # Message Reference ---- ------------------------- --------- 30 New-Pin [RFC2882] 31 Terminate-Session [RFC2882] 32 Password-Expired [RFC2882] 33 Event-Request [RFC2882] 34 Event-Response [RFC2882] 40 Disconnect-Request [DynAuth] 41 Disconnect-ACK [DynAuth] 42 Disconnect-NAK [DynAuth] 43 CoA-Request [DynAuth] 44 CoA-ACK [DynAuth] 45 CoA-NAK [DynAuth] 50 IP-Address-Allocate [RFC2882] 51 IP-Address-Release [RFC2882] 250-253 Experimental Use 254 Reserved 255 Reserved [RFC2865] Intellectual Property Statement The IETF takes no position regarding the validity or scope of any intellectual property or other rights that might be claimed to pertain to the implementation or use of the technology described in this document or the extent to which any license under such rights might or might not be available; neither does it represent that it has made any effort to identify any such rights.
