802.1x is an Institute of Electrical and Electronics Engineers (IEEE) standard that provides an 
authentication framework for wireless LANs (WLANs). 802.1x uses the Extensible 
Authentication Protocol (EAP) to exchange messages during the authentication process. The 
authentication protocols that operate inside the 802.1x framework that are suitable for wireless 
networks include EAP-Transport Layer Security (EAP-TLS), Protected EAP (PEAP), and EAP-
Tunneled TLS (EAP-TTLS). These protocols allow the network to authenticate the client while 
also allowing the client to authenticate the network.

802.1x authentication consists of three components:

•

The supplicant, or client, is the device attempting to gain access to the network. You can 
configure your system to support 802.1x authentication for wired users as well as wireless 
users.

•

The authenticator is the gatekeeper to the network and permits or denies access to the 
supplicants. The WFS709TP ProSafe Smart Wireless Switch acts as the authenticator, relaying 
information between the authentication server and supplicant. The EAP type must be 
consistent between the authentication server and supplicant and is transparent to the 
WFS709TP.

•

The authentication server provides a database of information required for authentication and 
informs the authenticator to deny or permit access to the supplicant.

The 802.1x authentication server is typically an EAP-compliant Remote Access Dial-In User 
Service (RADIUS) server that can authenticate either users (through passwords or certificates) 
or the client computer.
