Change a device role
The ExtraHop system automatically discovers and classifies devices on your network based on the protocol activity or device model and assigns a role to each device, such as a gateway, file server, database, or load balancer. You can change the role assigned to a device at anytime.
|Note:||After you change the device role, the device might be removed from or added to dynamic device groups that include a device role as criteria.|
