802.1X Security
802.1X is a server-based port authentication protocol which restricts unauthorized (rogue) clients from connecting to
a Local Area Network through a public port. In its simplest form, 802.1X usually involves three parties: supplicant
(client device), authenticator (Ethernet switch), and an authentication server. Before the device is permitted on the
network, port communication is restricted to Extensible Authentication Protocol over LAN (EAPOL) traffic.
If the device passes the authentication process, then the authentication server notifies the switch, allowing the client
to access the LAN. A full explanation of the 802.1X protocol is beyond the scope of this manual. However, the
illustration below shows the basic architecture.
