RADIUS Attributes

Remote Authentication Dial-In User Service (RADIUS) attributes are used to define specific authentication,
authorization, and accounting (AAA) elements in a user profile, which is stored on the RADIUS daemon.
This appendix describes the following types of RADIUS attributes supported in Broadband Network Gateway

RADIUS IETF Attributes

IETF Attributes Versus VSAs
RADIUS Internet Engineering Task Force (IETF) attributes are the original set of 255 standard attributes that
are used to communicate AAA information between a client and a server. Because IETF attributes are standard,
the attribute data is predefined and well known; thus all clients and servers who exchange AAA information
via IETF attributes must agree on attribute data such as the exact meaning of the attributes and the general
bounds of the values for each attribute.
RADIUS vendor-specific attributes (VSAs) derived from one IETF attribute-vendor-specific (attribute 26).
Attribute 26 allows a vendor to create an additional 255 attributes however they wish. That is, a vendor can
create an attribute that does not match the data of any IETF attribute and encapsulate it behind attribute 26;
thus, the newly created attribute is accepted if the user accepts attribute 26.
