6.5.1

ESXi shapes outbound network traffic on standard switches and inbound and outbound traffic on
distributed switches. Traffic shaping restricts the network bandwidth available on a port, but can also be
configured to allow bursts of traffic to flow through at higher speeds.
Average Bandwidth Establishes the number of bits per second to allow across a port, averaged
over time. This number is the allowed average load.
Peak Bandwidth Maximum number of bits per second to allow across a port when it is
sending or receiving a burst of traffic. This number limits the bandwidth that
a port uses when it is using its burst bonus.
Burst Size Maximum number of bytes to allow in a burst. If this parameter is set, a port
might gain a burst bonus if it does not use all its allocated bandwidth. When
the port needs more bandwidth than specified by the average bandwidth, it
might be allowed to temporarily transmit data at a higher speed if a burst
bonus is available. This parameter limits the number of bytes that have
accumulated in the burst bonus and transfers traffic at a higher speed.
Configure Trac Shaping for a vSphere Standard Switch or
Standard Port Group
ESXi lets you shape outbound traffic on standard switches or port groups. The traffic shaper restricts the
network bandwidth available to any port, but you can also configure it to temporarily allow bursts of traffic
to flow through a port at higher speeds.
The traffic shaping policies that you set at switch or port group level are applied at each individual port
that participates in the switch or port group. For example, if you set an average bandwidth of 100000
Kbps on a standard port group, 100000 Kbps averaged over time can pass through each port that is
associated with the standard port group.
Procedure
