I think you mean the individual ip address for a specific port? If your cisco equipment handles your dhcp you can find out by connecting to the switch via the blue cable that has ethernet on one side and serial on the other. If your server handles your dhcp then the switch will not know what the address is.

well, sure, but he said switchport, you can not have an IP address on a layer2 switch, that is why I want clarification.

Yes.... I need to get a specific port number for a specific IP address.
I can do a SHOW  MAC-ADDRESS ADDRESS XXXX.XXXX.XXXX and it will give me the assigned port.  But how can I get the assigned port if I only have the IP address?  What switch command can I use?
