Overview
8950 AAA is server software that is used to manage secure access to networks, servers,
and information services. Network elements that use a RADIUS server to manage access
are known as clients. An example of a RADIUS client might be a network access server
(NAS), a Wi-Fi access point, or even a Web page. 8950 AAA is a tool that promotes
system integrity not only for the network server, but also for the client-server relationship.
The next section provides a scenario showing the role that 8950 AAA plays within a
network.

basically how this is done. The term Network Access Server (NAS) is a term for a network
element that provides dial-up access services to a network. After the user connects to the
NAS, the NAS receives the user name and password from the user’s computer.
