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 (5–8). 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 5, 6, 7, and 8.
2. From the Port Control menu, select Unauthorized.
The Port Control setting for all other ports where authentication is not needed should be
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 5–8, 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 231 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 230).
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.
6. From the RADIUS Server Configuration screen, configure a RADIUS server with the
following settings:
• Server Address: 192.168.10.23
• Secret Configured: Yes
• Secret: secret123
• Active: Primary
