How to see which devices are communicating on a lan port?

I have a mikrotik RS125-24G-1S-IN and I need to be able to find out which devices on the network, either mac address or IP, are transmitting data on specific ports on the device. It’s a combination router/switch. I’m fairly new with mikrotik - is there a simple command to find this?

/ ip arp print

Will show devices and ports, assuming they are communicating with the router.

/ interface bridge host print

Will show devices connected to bridges.

I hope that helps
