802.1X Overview
The 802.1X protocol was proposed by IEEE 802 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 network access control protocol, 802.1X is used to perform port-level authentication
and control of devices connected to the 802.1X-enabled LAN ports. With the 802.1X protocol employed,
a user-side device can access the LAN only when it passes the authentication. Those devices that fail
to pass the authentication are denied access to the LAN.
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 .
