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).
