What kind of switches do you have? Most switches will tell you what port that MAC is plugged into.

I am experiencing a bit of a network problem with, at the moment, is more of an annoyance (but could easily get bigger!). Somewhere I have a NIC spewing out gratuitious ARP packets. (I did eventually hunt it down, but for the future...) Using Wireshark, I have the MAC address of the offending NIC. Again, for the future, is there a ping command switch or something else which will enable me to enter the MAC address and have the IP returned? Wireshark does indicate the offender is a Dell system. However, being mostly a Dell shop, pinging each node here and then examining my ARP cache is rather slow... Thanks! -- Richard D.
