Yes you can know which MAC Address belongs to who. As you can see below PC-ME is the computer attached and the Polycom is the VoIP phone.

If for whatever reason the devices appear the same and you can't determine by the device name. The CDP information will be the device directly connected to the port. So you can click on the "raw" and verify the mac address and IP address to make sure it's the VoIP phone.

Kind of a big deal

It says there Port 1. If you go to the actual port you should see a CDP/LLDP of what's connected to that switchport. If something is connected to the phone you should see both connections.

You will see all mac addresses being forwarded through the port. 

Thank you for your reply. If PC and ip phone are connected to the same port, i would see the two mac address based on what you said. From there, can i know which mac is from PC or IP phone?
