GS716Tv3, GS724Tv4, and GS748Tv5 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 is the default authentication mode. The 802.1X network has three components: • Authenticators. Specifies the port that is authenticated before permitting system access. • Supplicants. Specifies the host connected to the authenticated port requesting access to the system services. • Authentication Server. Specifies 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. The Port Authentication menu contains links to the features described in the following sections. • 802.1X Configuration • Port Authentication • Port Summary • Client Summary 802.1X Configuration Use the 802.1X Configuration screen to configure global port access control settings on the switch. The switch software supports.  To globally enable all 802.1X features: 1. Select Security > Port Authentication > Basic > 802.1X Configuration. 2. Next to Port Based Authentication State, select Enable. Note: If 802.1X is enabled, authentication is performed by a RADIUS server. This means the primary authentication method must be RADIUS. To set the method, select Security > Management Security > Authentication List and select RADIUS as method 1 for defaultList. For more information, see Authentication List Configuration on page 185. When port-based authentication is globally disabled, the switch does not check for 802.1X authentication before allowing traffic on any ports, even if the ports are configured to allow only authenticated users.
