FS728TP Smart Switch Software Administration Manual
A Port Access Entity (PAE) is able to adopt one of two distinct roles within an access control
interaction:
1. Authenticator: A Port that enforces authentication before allowing access to services
available via that Port.
2. Supplicant: A Port that attempts to access services offered by the Authenticator.
Additionally, there exists a third role:
3. Authentication server: Performs the authentication function necessary to check the
credentials of the Supplicant on behalf of the Authenticator.
All three roles are required in order to complete an authentication exchange.
The FS728TP Smart Switch supports the Authenticator role only, in which the PAE is
responsible for communicating with the Supplicant. The Authenticator PAE is also
responsible for submitting the information received from the Supplicant to the Authentication
Server in order for the credentials to be checked, which will determine the authorization state
of the Port. The Authenticator PAE controls the authorized/unauthorized state of the
controlled Port depending on the outcome of the RADIUS-based authentication process.
802.1X Example Configuration
This example shows how to configure the switch so that 802.1X-based authentication is
required on the ports in a corporate conference room (e1–e8). These ports are available to
visitors and need to be authenticated before granting access to the network. The
authentication is handled by an external RADIUS server. When the visitor is successfully
authenticated, traffic is automatically assigned to the guest VLAN. This example assumes
that a VLAN has been configured with a VLAN ID of 150 and VLAN Name of Guest.
1. From the Port Authentication screen, select ports e1 through e8.
2. From the Port Control menu, select Unauthorized.
The Port Control setting for all other ports where authentication is not needed should
Authorized. When the Port Control setting is Authorized, the port is unconditionally put in
a force-Authorized state and does not require any authentication. When the Port Control
setting is Auto, the authenticator PAE sets the controlled port mode
