GS716Tv2 and GS724Tv3 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.

switch switches support 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
