5. On the 802.1X Configuration page, set the port-based authentication state and guest VLAN
mode to Enable , and then click the Apply button. (See Configure Global 802.1X Settings
on page 243 .)
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 Configure RADIUS Servers on page 220 .
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 Authentication Lists on page 229 .)
This example enables 802.1X-based port security on the switch and prompts the hosts
connected on ports mg7–mg8 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 in a way
that is appropriate for STP and RSTP bridges.
An MSTP bridge can be configured to behave entirely as a RSTP bridge or an STP bridge.
So, an IEEE 802.1s bridge inherently also supports IEEE 802.1w and IEEE 802.1D.
The MSTP algorithm and protocol provide simple and full connectivity for frames assigned to
any given VLAN throughout a bridged LAN comprising arbitrarily interconnected networking
devices, each operating MSTP, STP, or RSTP. MSTP allows frames assigned to different
