Change a device name
The ExtraHop system automatically names devices by passively monitoring naming protocol traffic (DNS, DHCP, NETBIOS, CDP). If naming protocol traffic is not observed for a device, the device name displays the IP address for L3 devices or the MAC address for L2 devices. In either condition, you can change the automatic device name to a custom name. The custom name will appear throughout the ExtraHop system.
Note: | The ExtraHop system does not perform DNS lookups for device names. The ExtraHop system derives the DNS name for a device by observing DNS traffic over wire data. For more information, see Device discovery. |
