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. Traffic shaping policies do not apply to iSCSI traffic on a dependent hardware iSCSI adapter.


In the vSphere Client, display the Networking inventory view and select the dvPort group.


From the Inventory menu, select Network > Edit Settings.


Select Traffic Shaping.


In the Properties dialog box for the port group, click the Traffic Shaping tab.

You can configure both inbound traffic shaping and outbound traffic shaping. When traffic shaping is disabled, the options are dimmed.


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).
