Configuring the Switch
3-64
Web
– Click Security, Port Security. Set the action to take when an invalid address is
detected on a port, set the maximum number of MAC addresses allowed on a port,
and click Apply.

CLI
– This example sets the command mode to Port 5, sets the port security action
to send a trap and disable the port, and then enables port security for the switch.
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.
This switch uses the Extensible Authentication Protocol over LANs (EAPOL) to
exchange authentication protocol messages with the client, and a remote RADIUS
authentication server to verify user identity and access rights. When a client (i.e.,
Supplicant) connects to a switch port, the switch (i.e., Authenticator) responds with
an EAPOL identity request. The client provides its identity (such as a user name) in
