Port Authentication (802.1X) Commands
An authentication server must authenticate a client connected to an 802.1X switch port. Until the authentication, only
Extensible Authentication Protocol over LAN (EAPOL) traffic is allowed through the port to which a client is connected. After
authentication is successful, normal traffic passes through the port.
The Dell Networking OS supports RADIUS and Active Directory environments using 802.1X Port Authentication.
