SMC Networks SMC8150L2 manual Configuring 802.1X Port Authentication, Configuring Port Security

3 Configuring the Switch

Web – Click Security, Port Security. Set the action to take when an invalid address is detected on a port, mark the checkbox in the Status column to enable security for a port, set the maximum number of MAC addresses allowed on a port, and click Apply.

Figure 3-38 Configuring Port Security

CLI – This example selects the target port, sets the port security action to send a trap and disable the port and sets the maximum MAC addresses allowed on the port, and then enables port security for the port.

Console(config)#interface ethernet 1/5
Console(config-if)#port security action trap-and-shutdown	4-79
Console(config-if)#port security max-mac-count 20	4-79
Console(config-if)#port security	4-79
Console(config-if)#

Configuring 802.1X Port Authentication

Network switches can provide open and easy access to network resources by simply attaching a client PC. Although this automatic configuration and access is a desirable feature, it also allows unauthorized personnel to easily intrude and possibly gain access to sensitive network data.

The IEEE 802.1X (dot1X) standard defines a port-based access control procedure that prevents unauthorized access to a network by requiring users to first submit credentials for authentication. Access to all switch ports in a network can be centrally controlled from a server, which means that authorized users can use the same credentials for authentication from any point within the network.
