1.1 802.1x Overview
The 802.1x protocol was proposed by IEEE 802 LAN/WAN committee for security
problems on wireless LANs (WLAN). Currently, it is widely used on Ethernet as a
common port access control mechanism.
As a port-based network access control protocol, 802.1x authenticates and controls
accessing devices at the level of port. A device connected to an 802.1x-enabled port of
an access control device can access the resources on the LAN only after passing
authentication.

1.1.1 Architecture of 802.1x
802.1x operates in the typical client/server model and defines three entities: supplicant
system, authenticator system, and authentication server system, as shown in
