To restrict hosts from accessing the network if their MAC address is not approved, you should use the Port Security feature on the switch.
Key Takeaway: The Port Security feature on a switch stores the MAC address on a switch and allows only those MAC address to communicate on that port. If any other MAC address tries to communicate through the port, port security will disable the port.
