The process wireless clients go through when they connect to an AP and gain access to the network is a consistent one that consists of four phases. You can see the footprints of these phases if you check out the logs on the AP or the controller, or if you're viewing status fields in packet captures. These phases are:
The first phase involves the initial connection between the client and the AP. It's also when Layer 2 security mechanisms like None, Static WEP, 802.1X, WPA, and WPA2 come into play. If these mechanisms are employed and in place, the client will be forced to enter the appropriate password or have the required certificates or smart card in order to proceed and successfully make the connection.
This phase ...
