I would like to filter through cameras at the door 2 for mac address

I have a problem: I would like to filter through bridge port eth2 incoming cameras at the door 2 for mac address and outbound on port eth3 send them to the core switch. What are the steps to do?

Saw what? Let’s start off with what hardware and firmware are you using. Second, what is it you are actually trying to do? Setting up a filter based on a specific MAC or IP is easy enough, but I’m not really understanding what you are trying to accomplish. A little more detail please.

You can use bridge filter rules to achieve some level of mac address filtering, but that needs some experience. Take a look at the options and give it a shot.
