Chapter 16  IEEE 802.1X Commands 
IEEE 802.1X function is to provide an access control for LAN ports via the authentication. An 
802.1X system include three entities: supplicant, authenticator and authentication server.   
  Supplicant: the device that requests access to the LAN.   
  Authentication server: performs the actual authentication of the supplicant. It validates the 
identity of the supplicant and notifies the authenticator whether or not the supplicant is 
authorized to access the LAN.   
  Authenticator: controls the physical access to the network based on the authentication 
status of the supplicant. It is usually an 802.1X-supported network device, such as this 
TP-Link  switch. It acts as an intermediary (proxy) between the supplicant  and the 
authentication server, requesting identity information from the supplicant, verifying that 
information with the authentication server, and relaying a response to the supplicant. 
This chapter handles with the authentication process between the supplicant and the switch. 
To realize the authentication and accounting function, you should also enbable the AAA 
function and configure the RADIUS server. Go to Chapter 44 AAA Commands
 for more details.
