The classic way is probably to check the bridge tables in the switches beginning with the switch where the router is connected and trace it down switch by switch until you reach either the host or a hub/repeater/unmanaged switch. I also lookup sometimes the vendor of the device from the mac-address because this could help finding the device.
If you have to do this more often then a script can do this job via the SNMP protocol. Probably this functionality is included in some Network Management Applications ... hth Reinhold Jeffrey Reed wrote: > > What utilities are you guys using to find MAC addresses across > a large > campus network?
