Appendix E - IETF RADIUS Attributes Support 
Remote Authentication Dial-In User Service (RADIUS) attributes carry specific authentication, authorization, 
information and configuration details for the request and reply. This appendix lists the RADIUS attributes currently 
supported by the Switch. 
RADIUS attributes are supported by the IETF standard and Vendor-Specific Attribute (VSA). VSA allows the vendor to 
create an additionally owned RADIUS attribute. For more information about D-Link VSA, refer to the RADIUS 
Attributes Assignment Appendix. 
IETF standard RADIUS attributes are defined in the RFC 2865 Remote Authentication Dial-In User Service (RADIUS), 
RFC 2866 RADIUS Accounting, RFC 2868 RADIUS Attributes for Tunnel Protocol Support, and RFC 2869 RADIUS 
Extensions.
