CHAPTER 17 Internal RADIUS Server 17.1 Overview This chapter describes how the NWA can use its internal RADIUS server to authenticate wireless clients. Remote Authentication Dial In User Service (RADIUS) is a protocol that enables you to control access to a network by authenticating user credentials. The following figure shows the NWA (Z) using its internal RADIUS server to control access to a wired network. A wireless notebook (A) requests access by sending its credentials. The NWA consults its internal RADIUS server's list of user names and passwords. If the credentials of the wireless notebook match an entry, the NWA allows the client to access the network. Figure 118 RADIUS Server Access Request Z Wired Network A Allow / Deny The NWA can also serve as a RADIUS server to authenticate other APs and their wireless clients. For more background information on RADIUS, see Section 11.2 on page 175. NWA-3500/NWA-3550 User's Guide 209
