RADIUS Attributes


Remote Authentication Dial-In User Service (RADIUS) attributes are used to define specific authentication, authorization, and accounting elements in a user profile, which is stored on the RADIUS daemon. This appendix lists the RADIUS attributes currently supported.

How to Use This Appendix

This appendix is divided into two sections:

Supported RADIUS Attributes

Comprehensive List of RADIUS Attributes

The first section lists the Cisco IOS releases in which supported Internet Engineering Task Force (IETF) RADIUS and vendor-proprietary RADIUS attributes are implemented. The second section provides a comprehensive list and description of both IETF RADIUS and vendor-proprietary RADIUS attributes.

Supported RADIUS Attributes

lists Cisco-supported IETF RADIUS attributes and the Cisco IOS release in which they are implemented. In cases where the attribute has a security server-specific format, the format is specified.


Note   Attributes implemented in special (AA) or early development (T) releases will be added to the next mainline image.

1 Only stop records contain multi-session IDs. This is because start records are issued before any multilink processing takes place.

2 Only stop records contain link counts. This is because start records are issued before any multilink processing takes place.

3 This RADIUS attribute complies with the following two draft IETF documents: "RADIUS Attributes for Tunnel Protocol Support" and "RADIUS Accounting Modifications for Tunnel Protocol Support."


lists Cisco-supported vendor-proprietary RADIUS attributes and the Cisco IOS release in which they are implemented. In cases where the attribute has a security server-specific format, the format is specified.


Note   Attributes implemented in special (AA) or early development (T) releases will be added to the next mainline image.

Comprehensive List of RADIUS Attributes

The following two sections provide a comprehensive listing and description of known RADIUS attributes:

RADIUS IETF Attributes

RADIUS Vendor-Proprietary Attributes

RADIUS IETF Attributes

lists and describes IETF RADIUS attributes. In cases where the attribute has a security server-specific format, the format is specified.

Table 33 RADIUS IETF Attributes 

Number
IETF Attribute
Description

1

User-Name

Indicates the name of the user being authenticated.

2

User-Password

Indicates the user's password or the user's input following an Access-Challenge. Passwords longer than 16 characters are encrypted using the IETF Draft #2 (or later) specifications.

3

CHAP-Password

Indicates the response value provided by a PPP Challenge-Handshake Authentication Protocol (CHAP) user in response to an Access-Challenge.

4

NAS-IP Address

Specifies the IP address of the network access server that is requesting authentication.

5

NAS-Port

Indicates the physical port number of the network access server that is authenticating the user. The NAS-Port value (32 bits) consists of one or two 16-bit values (depending on the setting of the radius-server extended-portnames command). Each 16-bit number should be viewed as a 5-digit decimal integer for interpretation as follows:

For asynchronous terminal lines, async network interfaces, and virtual async interfaces, the value is 00ttt, where ttt is the line number or async interface unit number.

For ordinary synchronous network interface, the value is 10xxx.

For channels on a primary rate ISDN interface, the value is 2ppcc.

For channels on a basic rate ISDN interface, the value is 3bb0c.

For other types of interfaces, the value is 6nnss.

6

Service-Type

Indicates the type of service requested or the type of service to be provided.

In a request:

Framed for known PPP or SLIP connection.
Administrative-user for enable command.

In response:

Login—Make a connection.
Framed—Start SLIP or PPP.
Administrative User—Start an EXEC or enable ok.

Exec User—Start an EXEC session.

Service type is indicated by a particular numeric value as follows:

1: Login

2: Framed

3: Callback-Login

4: Callback-Framed

5: Outbound

6: Administrative

7: NAS-Prompt

8: Authenticate Only

9: Callback-NAS-Prompt

7

Framed-Protocol

Indicates the framing to be used for framed access.

Framing is indicated by a numeric value as follows:

1: PPP

2: SLIP

3: ARA

4: Gandalf-proprietary single-link/multilink protocol

5: Xylogics-proprietary IPX/SLIP

8

Framed-IP-Address

26

Vendor-Specific

Allows vendors to support their own extended attributes not suitable for general use. The Cisco RADIUS implementation supports one vendor-specific option using the format recommended in the specification. Cisco's vendor-ID is 9, and the supported option has vendor-type 1, which is named "cisco-avpair." The value is a string of the format:

protocol : attribute sep value

"Protocol" is a value of the Cisco "protocol" attribute for a particular type of authorization. "Attribute" and "value" are an appropriate AV pair defined in the Cisco TACACS+ specification, and "sep" is "=" for mandatory attributes and "*" for optional attributes. This allows the full set of features available for TACACS+ authorization to also be used for RADIUS. For example:

cisco-avpair= "ip:addr-pool=first"
cisco-avpair= "shell:priv-lvl=15"

The first example causes Cisco's "multiple named ip address pools" feature to be activated during IP authorization (during PPP's IPCP address assignment). The second example causes a user logging in from a network access server to have immediate access to EXEC commands.

lists supported vendor-specific RADIUS attributes (IETF Attribute 26). The "TACACS+ Attribute-Value Pairs" appendix provides a complete list of supported TACACS+ attribute-value (AV) pairs that can be used with IETF Attribute 26.

Data-Filter

Defines per-user IP data filters. These filters are retrieved only when a call is placed using a RADIUS outgoing profile or answered using a RADIUS incoming profile. Filter entries are applied on a first-match basis; therefore, the order in which filter entries are entered is important.

243

Call-Filter

Defines per-user IP data filters. On a Cisco router, this attribute is identical to the Data-Filter attribute.
