Extended RADIUS attributes
The RADIUS protocol features excellent extensibility. The Vendor-Specific attribute (attribute 26)
allows a vendor to define extended attributes. The extended attributes implement functions that the
standard RADIUS protocol does not provide.
A vendor can encapsulate multiple subattributes in the TLV format in attribute 26 to provide extended
functions. As shown in
, a subattribute encapsulated in attribute 26 consists of the following
parts:
•
Vendor-ID
—ID of the vendor. The most significant byte is 0. The other three bytes contains a
code compliant to RFC 1700.
•
Vendor-Type
—Type of the subattribute.
•
Vendor-Length
—Length of the subattribute.
•
Vendor-Data
—Contents of the subattribute.
The device supports the RADIUS subattributes with a vendor ID of 25506. For more information, see

Proprietary RADIUS subattributes (vendor ID 25506)

HWTACACS
HW Terminal Access Controller Access Control System (HWTACACS) is an enhanced security
protocol based on TACACS (RFC 1492). HWTACACS is similar to RADIUS, and uses a client/server
model for information exchange between the NAS and the HWTACACS server.
