RADIUS Overview
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 348.)
Figure 12 illustrates the interactions between wireless users (clients), MAP
access points, a WX switch, and its attached RADIUS servers when the
clients attempt access.
