Network switches provide easy and open access to resources by
simply attaching a client PC. Unfortunately this automatic
configuration also allows unauthorized personnel to easily intrude and
possibly gain access to sensitive data.
IEEE-802.1X provides a security standard for network access control,
especially in Wi-Fi wireless networks. 802.1X holds a network port
disconnected until authentication is completed. The switch uses
Extensible Authentication Protocol over LANs (EAPOL) to exchange
authentication protocol client identity (such as a user name) with the
client, and forward it to another remote RADIUS authentication server
to verify access rights. The EAP packet from the RADIUS server also
contains the authentication method to be used. The client can reject
the authentication method and request another, depending on the
configuration of the client software and the RADIUS server.
Depending on the authenticated results, the port is either made
