What are the steps involved to configure port security? How do we see a security violation?

 

Steps involved to configure port security

-Defining the interface as an access interface. This is done using the switchport mode access interface subcommand

-Enabling port security. This done using the switchport port-security interface command

-Defining which MAC addresses are permitted to send frames through this interface

Additional optional steps

-Defining what the switch should do if it receives a frame from a device that is not allowed

-Defining the number of MAC addresses allowed to use the port

How do we see a security violation?

To see the port security logs and status, we issue the 'show port-security' command. In the event of a security violation, the port sends logs of these violations which can be seen. These are the types of responses by ports to security violations; protect, restrict or shutdown
