GS748T Smart Switch Software Administration Manual 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. From the Port Authentication link, you can access the following pages: • Basic: • 802.1X Configuration on page 166 • Advanced: • Port Authentication on page 168 • Port Summary on page 172 802.1X Configuration Use the 802.1X Configuration page to enable or disable port access control on the system. To display the 802.1X Configuration page, click Security > Port Authentication > Basic > 802.1X Configuration. 166 | Chapter 5: Managing Device Security
