Extended RADIUS attributes
The RADIUS protocol features excellent extensibility. Attribute 26 (Vender-Specific), an attribute defined
by RFC 2865, allows a vender to define extended attributes to implement functions that the standard
RADIUS protocol does not provide.
A vendor can encapsulate multiple sub-attributes in the TLV format in RADIUS packets for extension of
applications. As shown in Figure 5, a sub-attribu
te encapsulated in Attribute 26 consists of the following
parts:
• Vendor-ID—Indicates the ID of the vendor. Its most significant byte is 0; the other three bytes
contains a code that is compliant to RFC 1700. For more information about the proprietary RADIUS
sub-attributes of HP, see "HP proprietary RADIUS sub-attributes."
• Ve
ndor-Type—Indicates the type of the sub-attribute.
• Vendor-Length—Indicates the length of the sub-attribute.
• Vendor-Data—Indicates the contents of the sub-attribute.
