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.
Dell Networking OS supports RADIUS and Active Directory environments using 802.1X Port Authentication.
Important Points to Remember
Dell Networking OS 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 supported on Dell Networking OS.
•
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.
•
If 802.1X authorization is enabled and all information from the RADIUS server is valid, the port is placed in the specified VLAN after
authentication.
•
If port security is enabled on an 802.1X port with VLAN assignment, the port is placed in the RADIUS server assigned VLAN.
•
If 802.1X is disabled on the port, it is returned to the configured access VLAN.
•
When the port is in the Force Authorized, Force Unauthorized, or Shutdown state, it is placed in the configured access VLAN.
•
If an 802.1X port is authenticated and put in the RADIUS server assigned VLAN, any change to the port access VLAN configuration
does not take effect.
•
The 802.1X with VLAN assignment feature is not supported on trunk ports, dynamic ports, or with dynamic-access port assignment
through a VLAN membership.
