# Global Configuration

Configuration > Global

You can enable or disable QoS using the Global Configuration dialog box. The source for QoS policies also can be specified using this dialog box. QoS can be based on a local configuration (using this application). This QoS source is configurable globally for the device, and for individual interfaces.

Note: The QoS configuration you select will only be enforced when QoS is enabled.
