1.10 IEEE 802.1X (RADIUS) Support  
IEEE 802.1X is an IEEE Standard for port-based Network Access Control (PNAC). It is  
part of the IEEE 802.1 group of networking protocols. It provides an authentication mecha-  
nism to devices wishing to attach to a LAN or WLAN. IEEE 802.1X defines the encapsulation  
of the Extensible Authentication Protocol (EAP) over IEEE 802, which is known as "EAP  
over LAN" or EAPoL.  
802.1X authentication involves three parties: a supplicant, an authenticator, and an  
authentication server (see Figure 1).  
Figure 1: IEEE 802.1X Functional Diagram  
• The supplicant is a client device (such as a laptop) that wishes to attach to the  
LAN/WLAN. The term ’supplicant’ is also used interchangeably to refer to the software  
running on the client that provides credentials to the authenticator.  
• The authenticator is a network device which provides a data link between the client  
(supplicant) and the network (LAN/WAN) and can allow or block network traffic between  
the two, such as an Ethernet switch or wireless access point. The authtenticator commu-  
nicates with the authentication server to determine if the network access for a supplicant  
will be granted or not.  
• The authentication server is typically a trusted server that can receive and respond  
to requests for network access, and can tell the authenticator if the connection is to be  
allowed, and various settings that should apply to that client’s connection or setting. Au-  
thentication servers typically run software supporting the RADIUS and EAP protocols.
