Blocking Wired devices?

Hi is there a way to block wired LAN devices because I don't want any unknown devices being plugged into my LAN and accessing the internet. There is a wireless MAC filter but I want it to function with Wired devices. (Wired MAC filter with whitelist and blacklist).

I want to prevent any possible wireless/wired MAC/IP spoofing on the network.
