You can configure additional settings to control access to the network through the
ports. See Configure a port security interface on page 706 for information about the
settings.

4. Click the Apply button.

5. On the 802.1X Configuration page, set the Port Based Authentication State and

Guest VLAN mode to Enable, and then the Apply button (See Configure the global
port security mode
on page 705).

This example uses the default values for the port authentication settings, but you
can configure several additional settings. 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. On the RADIUS Server Configuration page, configure a RADIUS server with the

following settings:

Server Address: 192.168.10.23

Secret Configured: Yes

Secret: secret123

Active: Primary

For more information, see RADIUS servers on page 635.

7. Click the Add button.

8. On the Authentication List page, configure the default List to use RADIUS as the first

authentication method (See Configure a login authentication list on page 650).

This example enables 802.1X-based port security on the switch and prompts the hosts
connected on ports 5 through 8 for an 802.1X-based authentication. The switch passes
the authentication information to the configured RADIUS server.

Multiple Spanning Tree Protocol

Spanning Tree Protocol (STP) runs on bridged networks to help eliminate loops. If a
bridge loop occurs, the network can become flooded with traffic. IEEE 802.1s Multiple
Spanning Tree Protocol (MSTP) supports multiple instances of spanning tree to efficiently
channel VLAN traffic over different interfaces. Each instance of the spanning tree behaves
in the manner specified in IEEE 802.1w, Rapid Spanning Tree, with slight modifications
in the working but not the end effect (chief among the effects is the rapid transitioning
of the port to the forwarding state).

The difference between RSTP and traditional STP (IEEE 802.1D) is the ability to configure
and recognize full-duplex connectivity and ports that are connected to end stations,
resulting in rapid transitioning of the port to the Forwarding state and the suppression
