For a list of the standard and extended RADIUS attributes and 3Com 
vendor-specific attributes (VSAs) supported by MSS, see “Supported 
RADIUS Attributes” on page 651.

Remote Authentication Dial-In User Service (RADIUS) is a distributed 
client-server system. RADIUS servers provide a repository for all 
usernames and passwords, and can manage and store large groups of 
users.

RADIUS servers store user profiles, which include usernames, passwords, 
and other AAA attributes. You can use authorization attributes to 
authorize users for a type of service, for appropriate servers and network 
segments through VLAN assignments, for packet filtering by access 
control lists (ACLs), and for other services during a session.

You must include RADIUS servers in a server group before you can access 
them. (See “Configuring RADIUS Server Groups” on page 524.)

Figure 33 illustrates the interactions between wireless users (clients), 
MAPs, a WX switch, and its attached RADIUS servers when the clients 
attempt access.
