5 In the Security group, select whether to reject or accept the Security policy exceptions.
Option Description
Promiscuous Mode
n
Reject — Placing a guest adapter in promiscuous mode has no effect
on which frames are received by the adapter.
n
Accept — Placing a guest adapter in promiscuous mode causes it to
detect all frames passed on the vSphere distributed switch that are
allowed under the VLAN policy for the port group that the adapter is
connected to.
MAC Address Changes
n
Reject — If you set the MAC Address Changes to Reject and the guest
operating system changes the MAC address of the adapter to anything
other than what is in the .vmx configuration file, all inbound frames
are dropped.
If the Guest OS changes the MAC address back to match the MAC
address in the .vmx configuration file, inbound frames are passed
again.
n
Accept — Changing the MAC address from the Guest OS has the
intended effect: frames to the new MAC address are received.
Forged Transmits
n
Reject — Any outbound frame with a source MAC address that is
different from the one currently set on the adapter are dropped.
n
Accept — No filtering is performed and all outbound frames are
passed.

Traffic Shaping Policy
A traffic shaping policy is defined by average bandwidth, peak bandwidth, and burst size. You can establish
a traffic shaping policy for each port group and each distributed port or distributed port group.
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.
