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


Verify that the vSphere Distributed Switch version is 5.1.0 and later.


  1. In the vSphere Web Client, navigate to the distributed switch.
  2. From the Actions menu, select 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.
