GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches Port Authentication In port-based authentication mode, when 802.1x is enabled globally and on the port, successful authentication of any one supplicant attached to the port results in all users being able to use the port without restrictions. At any given time, only one supplicant is allowed to attempt authentication on a port in this mode. Ports in this mode are under bidirectional control. This mode is the default authentication mode. The 802.1x network has three components: • Authenticators. Specify the port that is authenticated before permitting system access. • Supplicants. Specify the host connected to the authenticated port requesting access to the system services. • Authentication Server. Specify the external server, for example, the RADIUS server that performs the authentication on behalf of the authenticator, and indicates whether the user is authorized to access system services. From the Port Authentication menu, you can access features described in the following sections: • 802.1x Configuration • Port Authentication • Port Summary 802.1x Configuration Use the 802.1x Configuration screen to enable or disable port access control on the system, to enable, or disable the Guest VLAN (which allows unauthenticated users to have limited access to the network resources) and to enable or disable the forwarding of EAPoL frames when 802.1x is disabled on the device.  To configure global 802.1x settings: 1.
