Intro duction to 802.1x
The 802.1x protocol (802.1x for short) was developed by IEEE802 LA
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 acc
a user-side device can access the
authentication are denied when accessing the LAN.
