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.
Important Points to Remember
The system limits network access for certain users by using VLAN assignments. 802.1X with VLAN assignment
has these characteristics when configured on the switch and the RADIUS server.
• 802.1X is not supported on the LAG or the channel members of a LAG.
• If no VLAN is supplied by the RADIUS server or if 802.1X authorization is disabled, the port is configured
in its access VLAN after successful authentication.
• If 802.1X authorization is enabled but the VLAN information from the RADIUS server is not valid, the port
returns to the Unauthorized state and remains in the configured access VLAN. This prevents ports from
appearing unexpectedly in an inappropriate VLAN due to a configuration error. Configuration errors
create an entry in Syslog.
