If your device is getting unwanted traffic and it's causing issues, I think the best solution is to use something like Wire Shark and trace down the unwanted traffic and put a stop to it. Just my opinion.
PS - A bad switch can cause unwanted traffic to an IP address because the IP/host table becomes corrupt. Try chaging ports or change the switch itself.
