I am trying to find what is on the other end of a couple of wildly run CAT5 cables. They are plugged into a CISCO 4006 and instead of just unplugging them and waiting to hear who complains. I wanted to know if anyone could help me. From within the a terminal session I could get the MAC address of what is on the other end but does anyone know of a way that I could relate that to an ip address. Is there some sort of reverse arp lookup command or program?

Thanks in advance....
