To block unauthorized access to switch ports, switches support a feature called port security. This feature allows you to configure which devices are allowed or blocked on each port. This number is the total of available MAC addresses, including those used for other Layer 2 functions and any other secure MAC addresses. Learn how to configure port security on Cisco switches to prevent unauthorized network access and pass your CCNA 200-301 exam.
