resolve ip address from a switch port

We have been using old smarthubs for the last 8 years and now just installed hp procurve switches.

Can anyone explain to me how I can resolve ip address from the switch ports. I have a switch in a bldg. and I want to know who is connect to port 30 on my switch. It’s up and active but I can’t identify what device is connected to it.

I have read some documentation and tried to view my arp tables but the specific port isn’t listed.

I have the mac address of the device that’s on the port but I am at a loss.

Is there any software or a better way of doing this.
