5 Specify network traffic parameters.
Option Description
Average Bandwidth
Establishes the number of bits per second to allow across a port, averaged
over time—the allowed average load.
Peak Bandwidth
The maximum number of bits per second to allow across a port when it is
sending/receiving a burst of traffic. This tops the bandwidth used by a port
whenever it is using its burst bonus.
Burst Size
The maximum number of bytes to allow in a burst. If this parameter is set,
a port may gain a burst bonus when it doesn’t use all its allocated
bandwidth. Whenever the port needs more bandwidth than specified by
Average Bandwidth, it may be allowed to temporarily transmit data at a
higher speed if a burst bonus is available. This parameter tops the number
of bytes that may be accumulated in the burst bonus and thus transferred
at a higher speed.

Edit Distributed Port or Uplink Port Traffic Shaping Policies
ESXi allows you to shape both inbound and outbound traffic on vSphere distributed switches. The traffic
shaper restricts the network bandwidth available to any port, but may also be configured to 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.
Prerequisites
Launch the vSphere Client and log in to a vCenter Server system.
Procedure
1 Log in to the vSphere Client and select the Networking inventory view.
2 Select the vSphere distributed switch in the inventory pane.
3 On the Ports tab, right-click the port to modify and select Edit Settings.
4 Click Policies.
5 In the Traffic Shaping group, you can configure both Inbound Traffic Shaping and Outbound Traffic
Shaping.
When traffic shaping is disabled, the tunable features are dimmed.
Status — If you enable the policy exception for either Inbound Traffic Shaping or Outbound Traffic
Shaping 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, clear connection to the physical network by default.
