Which command used to verify port security can be used to determine if the port has been disabled by a port security violation?

A. show running-config

B. show port-security violations

C. show port-security interface interface#

D. debug mac-address table

Solution

C is correct. After entering this command, the interface display will show “Port Status: Secure-up.” If a violation has occurred, it will read “Port Status: Secure-shutdown.”

A, B, and D are incorrect. A is incorrect because show run will display the commands used to enforce port security, but does not indicate the state of the interface. B and D are incorrect because these commands do not exist.
