Netgear S3300-28X-PoE+ (GS728TXP) - ProSAFE S3300 Smart Switch Series 管理者ガイド

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.

Use the 802.1X Configuration screen to configure global port access control settings on the 
switch. The switch software supports.

to allow only authenticated users.
