Change a device model

The ExtraHop system observes the network traffic on devices to automatically determine the vendor make and model, but you can manually change the device model.

Here are some important considerations about changing a device model:

  • Devices are automatically added and removed from dynamic device groups with criteria based on device models.
  • You can change a device model from sensors and consoles. When the device is updated on a console, the change is synchronized to connected sensors. However, the change is not synchronized from individual sensors to the connected console.
