A.
show interfaces port-security

B.
show port-security interface

C.
show ip interface

D.
show interfaces switchport

Explanation:
The output is the result of executing the show port-security interface command. The sample output indicates
that port security has been enabled on the interface, and that a maximum of two MAC addresses has been
configured. A violation mode of Shutdown indicates that if a third MAC address attempts to make a connection,
the switch port will be disabled. It is useful to note that you must specify a port number when you execute the
command. In this case, the command was Switch# show port-security interface fastethernet0/1.
The output was not produced by the show interfaces port-security command. This is not a valid Cisco
command.
The output was not produced by the show ip interface command. It displays protocol-related information about
an interface, and nothing pertaining to switch port security. An example of its output follows:
