Configuring 802.1X Features

IEEE 802.1X and MAC RADIUS authentication both provide network edge security, protecting Ethernet LANs from unauthorized user access by blocking all traffic to and from devices at the interface until the supplicant's credential or MAC address is presented and matched on the authentication server (a RADIUS server). When the supplicant is authenticated, the switch stops blocking access and opens the interface to the supplicant.

See the Junos OS Documentation for EX Series Switches for detailed examples of configuring 802.1X features.
