GS716Tv2 and GS724Tv3 Software Administration Manual
Configuration Examples B-11
v1.0, July 2009
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 5-3 .
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 5-13 ).
This example enables 802.1X-based port security on the GS716T/GS724T switch and prompts the
hosts connected on ports g21-g24 for a 802.1X-based authentication. The switch passes the
authentication information to the configured RADIUS server. The RADIUS server must be
configured to allow access on the Guest VLAN.
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.
