Enable network resource management on a vSphere Distributed Switch to guarantee minimum bandwidth to system traffic for vSphere features and to virtual machine traffic.


  1. On the vSphere Client Home page, click Networking and navigate to the distributed switch.
  2. From the Actions menu, select Settings > Edit Settings.
  3. From the Network I/O Control drop-down menu, select Enable.
  4. Click OK.


When enabled, the model that Network I/O Control uses to handle bandwidth allocation for system traffic and virtual machine traffic is based on the Network I/O Control version that is active on the distributed switch. See About vSphere Network I/O Control Version 3.
