1.1 Introduction to 802.1X
The LAN defined in IEEE 802 protocols does not provide access authentication. In
general, users can access network devices or resources in a LAN as long as they
access the LAN. When it comes to application circumstances like telecom network
access, building, LAN and mobile office, however, administrators need to control and
configure the access of user devices. Therefore, port- or user-based access control
comes into being.
802.1x is a port-based network access control protocol. It is widely accepted by
vendors, service providers and end users for its low cost, superior service continuity
and scalability, and high security and flexibility.
