IEEE 802.1x Introduction
IEEE 802.1x port-based authentication is desired to prevent unauthorized devices (clients) from gaining access to the network. As
LANs extend to hotels, airports, and corporate lobbies, insecure environments could be created. 802.1x port-based network access
control makes use of the physical access characteristics of IEEE 802 LAN infrastructures, such as 802.3 Ethernet, 802.11 Wireless
LAN and VDSL LRE (Long Reach Ethernet), in order to provide a means of authenticating and authorizing devices attached to a LAN
port that has point-to-point connection characteristics, and of preventing access to that port in cases the authentication process fails.
IEEE 802.1x authentication is a client-server architecture delivered with EAPOL (Extensible Authentication Protocol over LAN). The
authentication server authenticates each client connected to a Access Point (For Wireless LAN) or switch port (for Ethernet) before
accessing any services offered by the Wireless AP. 802.1x contains tree major components :
