55 © 2004, Cisco Systems, Inc. All rights reserved. Authentication and Association Types Forming an Association is an 8 step process: 1.Clients start off being Unauthenticated and unassociated 2.All access points (AP’s) transmit a beacon management frame at a fixed interval 3.Clients listens for beacon messages to identify AP’s in range 4.The client selects a network it wishes to join 5.The client and AP send management frames to each other, and perform mutual authentication 6.If authentication is successful, the client is Authenticated, but remains unassociated. (The AP knows who it is, but is yet to allocate resources to it) 7.Client sends association request frames to the AP, which responds with association response frames. 8.Client is granted access to services, and thus becomes Associated.
