Enable network resource management on a vSphere Distributed Switch to guarantee minimum bandwidth to system traffic for vSphere features and to virtual machine traffic.
- In the vSphere Web Client, navigate to the distributed switch.
- From the Actions menu, select Edit Settings.
- From the Network I/O Control drop-down menu, select Enable.
- 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.
