Access the command line for S1 and enable port security on Fast Ethernet ports 0/1 and 0/2. Port security allows you to restrict a port’s ingress traffic by limiting the MAC addresses that are allowed to send traffic to the port.Ī. In this activity, you will configure and verify port security on a switch.
