7.4 Configuring Quality of Service (QoS)

Prior to configuring Quality of Service, you must install Data Center Bridging using one of the

following methods:

 To install the Data Center Bridging using the Server Manager:

Step 1. Open the 'Server Manager'.

Step 2. Select 'Add Roles and Features'.

Step 3. Click Next.

Step 4. Select 'Features' on the left panel

Step 5. Check the 'Data Center Bridging' checkbox.

Step 6. Click 'Install'.

 To install the Data Center Bridging using PowerShell:

Step 1. Enable Data Center Bridging (DCB).

 To configure QoS on the host:

Step 1. Change the Windows PowerShell execution policy.

Step 2. Remove the entire previous QoS configuration.

Step 3. Set the DCBX Willing parameter to false as Mellanox drivers do not support this feature.

Step 4. Create a Quality of Service (QoS) policy and tag each type of traffic with the relevant priority.

In this example we used TCP/UDP priority 1, ND/NDK priority 3.
