I have located an IP address that is causing problems on my network. I have just installed Whats Up Gold, if this is of any relevance. What I would like to do is locate which switch and which port on that switch this IP address is allocated to so that I can find the device. Does anyone know how I can do that? I included the bit about whats up gold because I am not sure if it is possible with this software. Thanks for all of your help.
