Interface MAC limitation

Hi,

I have not managed to find a answer on the forums for this question.

Does anyone know a way for me to limit one MAC address per physical port. So for instance for a 24port device i would like to set-up 20 ports that each can only have one MAC connected at a time and it needs to be allowed by me.

Thank you for your answers in advance.

Something like what is discussed here?
