ip-mac-port binding?

Question

Network administration

The d'link DES-3028 L2 switch has the ip-mac-port-binding function, which binds the computer's ip-mac bundle to the switch port. Everything works all cool, but I want to understand the logic.
How does the switch understand which ip came to it on the port if it only works with frames and does not operate with ip packets?
