You can shape both inbound and outbound traffic on vNetwork Distributed Switches. You can restrict the network bandwidth available to a port, but you can also temporarily allow bursts of traffic to flow through a port at higher speeds.

A traffic shaping policy is defined by three characteristics: average bandwidth, peak bandwidth, and burst size.

To edit the traffic shaping policies on an individual dvPort, the associated dvPort group must be set to allow policy overrides.


Log in to the vSphere Client and display the vNetwork Distributed Switch.


On the Ports tab, right-click the port to modify, and select Edit Settings.


Click Policies.


In the Traffic Shaping group, you can configure both inbound traffic shaping and outbound traffic shaping.

When traffic shaping is disabled, the options are dimmed.




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).
