Device name precedence

Discovered devices are automatically named based on multiple sources of network data such as protocols, MAC or IP addresses, or device roles. When multiple names are found for a device, the order of device name precedence specifies which name is displayed by default in the ExtraHop system.

The ExtraHop system defaults to the following order of precedence:

  • Custom Name
  • Cloud Instance Name
  • CDP Name
  • DHCP Name
  • DNS Name
  • NetBIOS Name
  • Default Name

Before you begin

  • Device name precedence settings only apply to the console or sensor on which the settings are configured.
  1. Log in to the ExtraHop system through https://<extrahop-hostname-or-IP-address>.
  2. Click the System Settings icon and then click All Administration.
  3. In the System Configuration section, click Device Name Precedence.
  4. Click and drag device names to create a new order of precedence.
  5. Click Save.
  6. (Optional): Click Revert to Default to undo your changes.
