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 168
• Advanced:
• Port Authentication on page 169
• Port Summary on page 173
