802.1X Port Authentication
The switch supports IEEE 802.1X (dot1x) port-based access control that prevents
unauthorized access to the network by requiring users to first submit credentials for
authentication. Client authentication is controlled centrally by a RADIUS server
using EAP (Extensible Authentication Protocol).
dot1x system-auth-control
This command enables IEEE 802.1X port authentication globally on the switch.
Use the no form to restore the default.
