Introduction to 802.1x
The 802.1x protocol (802.1x for short) was developed by IEEE802 LAN/WAN committee to
address security issues of wireless LANs. It was then used in Ethernet as a common
access control mechanism for LAN ports to address 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 devices. With the 802.1x
protocol employed, a user-side device can access the LAN only when it passes the
authentication. Those fail to pass the authentication are denied when accessing the LAN.
