> # Enabling or Disabling Control Traffic

> By default, the QoS feature for certain critical control traffic is enabled. These critical control frames are assigned the highest (absolute) priority.

> Tip We do not recommend disabling this feature as all critical control traffic is automatically assigned the lowest priority once you issue this command.

> ## Detailed Steps

> To enable or disable the high priority assignment for control traffic using Fabric Manager, follow these steps:

> 1. Expand Switches, expand FC Services and then select QoS in the Physical Attributes pane.

> The QoS control traffic information is displayed in the Information pane. The Control tab is default.

> 2. Select the switch on which you want to enable or disable control traffic.
> 3. In the Command column, click the drop-down menu and select enable or disable.
> 4. Click Apply Changes to save your changes.
