802.1X Overview
The 802.1X protocol was proposed by IEEE802 LAN/WAN committee for security of wireless LANs
(WLAN). It has been widely used on Ethernet as a common port access control mechanism.
As a port-based access control protocol, 802.1X authenticates and controls accessing devices at the
port level. 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.
The port security feature provides rich security modes that combine or extend 802.1X and MAC
address authentication. In a networking environment that requires flexible use of 802.1X and MAC
address authentication, you are recommended to configure the port security feature. In a network
environment that requires only 802.1X authentication, you are recommended to configure the 802.1X
directly rather than configure the port security feature for simplicity sake. For how to use the port
security feature, refer to Port Security Configuration in the Security Volume.
