13.5 802.1X

The 802.1X protocol was developed by IEEE802 LAN/WAN committee to deal with the security

issues of wireless LANs. It was then used in Ethernet as a common access control mechanism for

LAN ports to solve mainly authentication and security problems.

802.1X is a port-based network access control protocol. It authenticates and controls devices

requesting for access in terms of the ports of LAN access control devices. With the 802.1X

protocol enabled, a supplicant can access the LAN only when it passes the authentication,

whereas those failing to pass the authentication are denied when accessing the LAN.

Architecture of 802.1X Authentication

802.1X adopts a client/server architecture with three entities: a supplicant system, an

authenticator system, and an authentication server system, as shown in the following figure.
