Using IP/MAC Address Finder

The IP/MAC Finder tool provides an easy way to locate an IP or MAC address on the network. Using the previously discovered network devices, IP/MAC Finder will find and display network interfaces that have sighting information for the supplied IP or MAC address. To get the most up-to-date sighting information, you can use the Refresh button which sends SNMP requests to each network device to quickly update the sighting information.

When enough network data is available, IP/MAC Finder indicates to which network interface the IP or MAC address is physically connected.

To access the IP/MAC Finder tool:

On the WhatsUp Gold web interface, go to Tools > IP/MAC Address Finder.
