How do find out which computer is connected to this port ?

We have a 48 ports Cisco switch and according to the latest stats, port 28 on this switch is generating a lot of collisions. Physically I can only manage to find out Port 28 of the switch is connected to the port 3 of our patch panel. However, we do not do a proper job of labeling all the wall data jack #, so that's why I still cannot figure out which PC is using port 28 on the switch.

Software tools I have is Cisco network Assistant.

I am not a Cisco guy and I am windows guy, please help.

Need the answer or solution before 3:15 pm Pacific Standard Time, Please help !!

The DHCP-server could help with: who has a lease with that MAC-adress.

Turn that port off and see who complains, that is usually a quick step...another would be to compare the mac address from the switch arp tables with your dhcp scope to get a machine name and track it down that way

sh mac- | inc 0/28

will show you the MAC address of the client that's connected to this port.
