Configuring Port Security Beginning in Privileged EXEC mode, use the following commands to enable port security on an interface to limit the number of source MAC addresses that can be learned. Command configure interface interface port security [discard] [trap seconds] port security max maxaddr CTRL + Z show ports security [interface] show ports security addresses [interface] Purpose Enter Global Configuration mode. Enter interface configuration mode for the specified interface. The interface variable includes the interface type and number, for example gigabitethernet 1/0/3. You can also specify a range of interfaces with the interface range command, for example, interface range gigabitethernet 1/0/8-12 configures interfaces 8, 9, 10, 11, and 12. Enable port security on the port. This prevents the switch from learning new addresses on this port after the maximum number of addresses has been learned. • discard - Discards frames with unlearned source addresses. This is the default if no option is indicated. • trap seconds - Sends SNMP traps and defines the minimal amount of time in seconds between two consecutive traps. (Range: 1-1000000) Set the maximum number of MAC addresses that can be learned on the port while port security is enabled. Exit to Privileged EXEC mode. View port security settings on all interfaces or the specified interface. View the current MAC addresses that have been learned on all ports or the specified port.
