Managing Authentication Servers RADIUS Servers
OmniSwitch 6600 Family Network Configuration Guide April 2006 page 20-9
RADIUS Servers
RADIUS is a standard authentication and accounting protocol defined in RFC 2865 and RFC 2866. A
built-in RADIUS client is available in the switch. A RADIUS server that supports Vendor Specific
Attributes (VSAs) is required. The Alcatel attributes may include VLAN information, time-of-day, or
slot/port restrictions.
RADIUS Server Attributes
RADIUS servers and RADIUS accounting servers are configured with particular attributes defined in RFC
2138 and RFC 2139, respectively. These attributes carry specific authentication, authorization, and config-
uration details about RADIUS requests to and replies from the server. This section describes the attributes
and how to configure them on the server.
Standard Attributes
The following tables list RADIUS server attributes 1–39 and 60–63, their descriptions, and whether the
Alcatel RADIUS client in the switch supports them. Attribute 26 is for vendor-specific information and is
discussed in “Vendor-Specific Attributes for RADIUS” on page 20-11. Attributes 40–59 are used for
RADIUS accounting servers and are listed in “RADIUS Accounting Server Attributes” on page 20-13.
