I have to find where a server nic is connected in the network. I was certain there was a way to know what mac address was on which port but I needed Google to find a good article to show me how to get that information.
Once on the switch you can simply execute:
sh mac address-table
to see all the mac addresses the switch is aware of but when you are looking for a specific mac address you can execute this:
sh mac-address-table address 0011.bbcc.ddzz
Very simple and very convenient if I could only find the nic somewhere.
