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 (g1–g8). 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 g1 through g8.

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.

3. In the Guest VLAN field for ports g1–g8, enter 150 to assign these ports to the guest VLAN.

You can configure additional settings to control access to the network through the ports.

See Port Security Interface Configuration on page 221 for information about the settings.

4. Click Apply.

5. From the 802.1X Configuration screen, set the Port Based Authentication State and Guest

VLAN Mode to Enable, and then click Apply (See Port Security Configuration on

page 220).

This example uses the default values for the port authentication settings, but there are

several additional settings that you can configure. For example, the EAPOL Flood Mode

field allows you to enable the forwarding of EAPoL frames when 802.1X is disabled on

the device.
