Configuring QoS by Disabling DCBX on the Adapter
All configuration must be completed on all of the systems in use before 
configuring QoS by disabling DCBX on the adapter. The priority-based flow 
control (PFC), enhanced transition services (ETS), and traffic classes 
configuration must be the same on the switch and server.
To configure QoS by disabling DCBX:
1. Disable DCBX on the adapter.
2. Using HII, set the RoCE Priority to 0.
3. To install the DCB role in the host, issue the following Windows PowerShell 
command:
PS C:\Users\Administrators> Install-WindowsFeature 
Data-Center-Bridging
4. To set the DCBX Willing mode to False, issue the following Windows 
PowerShell command:
PS C:\Users\Administrators> set-NetQosDcbxSetting -Willing 0
5. Enable QoS in the miniport as follows:
a. Open the miniport Properties, and then click the Advanced tab.
b. On the adapter properties’ Advanced page (Figure 15-9) under 
Property, select Quality of Service, and then set the value to 
Enabled.
c. Click OK.
