GS752TXS and GS728TXS Smart Switches 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 220 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 219). 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 For more information, see RADIUS Configuration on page 191. 7. Click Add. 8. From the Authentication List screen, configure the default List to use RADIUS as the first authentication method (See Authentication List Configuration on page 198). This example enables 802.1X-based port security on the GS752TXS/GS728TXS switch and prompts the hosts connected on ports g1-g8 for an 802.1X-based authentication. The switch passes the authentication information to the configured RADIUS server. MSTP 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 the RSTP and the 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 of Topology Change Notification. These features are represented by the parameters pointtopoint and edgeport. MSTP is compatible to both RSTP and STP. It behaves appropriately to STP and RSTP bridges. A MSTP bridge can be configured to behave entirely as a RSTP bridge or a STP bridge. So, an IEEE 802.1s bridge inherently also supports IEEE 802.1w and IEEE 802.1D. 309
