4 Configure traffic shaping policies.
Option Description
Status Enables setting limits on the amount of networking bandwidth allocated for each
port that is associated with the standard switch or port group.
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
a burst of traffic. This setting tops the bandwidth used by a port whenever it is
using its burst bonus. This parameter can never be smaller than the average
bandwidth.
Burst Size The maximum number of bytes to allow in a burst. If this parameter is set, a port
might gain a burst bonus when it does not use all its allocated bandwidth.
Whenever the port needs more bandwidth than the average bandwidth specifies,
the port can temporarily transmit data at a higher speed if a burst bonus is
available. This parameter tops the number of bytes that can accumulate in the
burst bonus and can be transferred at a higher speed.
5 For each traffic shaping policy (Average Bandwidth, Peak Bandwidth, and Burst Size), enter a
bandwidth value.
6 Click OK.
Edit the Trac Shaping Policy on a Distributed Port Group or
Distributed Port
You can shape both inbound and outbound traffic on vSphere distributed port groups or distributed ports.
The traffic shaper restricts the network bandwidth for any port in the group, but might also be configured
to temporarily allow “bursts” of traffic to flow through a port at higher speeds.
The traffic shaping policies that you set at distributed port group level are applied on each individual port
that participates in the port group. For example, if you set an average bandwidth of 100000 Kbps on a
distributed port group, 100000 Kbps averaged over time can pass through each port that is associated
with the distributed port group.
Prerequisites
To override a policy on distributed port level, enable the port-level override option for this policy. See
Configure Overriding Networking Policies on Port Level.
Procedure
1 In the vSphere Web Client, navigate to the distributed switch.
