9 RADIUS Attributes
Remote Authentication Dial-In User Service (RADIUS) is an industry standard for providing
identification, authentication, authorization, and accounting services for distributed dial-up/remote
access networking.
RADIUS Vendor-Specific Attributes (VSAs)
RADIUS Vendor-Specific Attributes (VSAs) are RADIUS Authentication and Accounting attributes
defined by vendors to customize information exchanges between clients and servers. This allows unique
behaviors to be implemented in client applications without requiring custom server development. VSA
support is included directly in dictionary files distributed with RADIUS server products (for example,
Funk Steel Belted RADIUS), or can be configured manually on most server products.
Table 9 defines the Extreme Networks VSAs currently implemented in the Summit WM Controller,
Access Points and Software solution, defined using the Extreme Networks Organizationally Unique
Identifier (OUI):
