Use traffic shaping policies to control the bandwidth and burst size on a vSwitch.


Log in to the vSphere Client and select the host from the inventory panel.


Click the Configuration tab, and click Networking.


Click Properties for the vSwitch to edit.


In the Properties dialog box, click the Ports tab.


Select the vSwitch item and click Edit.


In the Properties dialog box, click the Traffic Shaping tab.

When traffic shaping is disabled, the options are dimmed. You can selectively override all traffic-shaping features at the port group level if traffic shaping is enabled.

This policy is applied to each individual virtual adapter attached to the port group, not to the vSwitch as a whole.


Peak bandwidth cannot be less than the specified average bandwidth.




If you enable the policy exception in the Status field, you are setting limits on the amount of networking bandwidth allocated for each virtual adapter associated with this particular port group. If you disable the policy, services have a free and clear connection to the physical network.

Average Bandwidth

A value measured over a particular period of time.

Peak Bandwidth

Limits the maximum bandwidth during a burst. It can never be smaller than the average bandwidth.

Burst Size

Specifies how large a burst can be in kilobytes (KB).
