Figure 3.47 Primary properties for a network adapter
The core properties for a network adapter are as follows:
Virtual Switch The virtual switch to which the adapter should be connected
Enable Virtual LAN Identification If the switch port to which the virtual
switch is connected is set to tagged and expects packets to be tagged with a VLAN
ID, this option allows you to configure which VLAN ID packets from this network
adapter will be tagged.Enable Bandwidth Management (not available for legacy network
adapter) Enables limits to be specified in Mbps for the bandwidth available for the
network adapter. The lowest value allowed for Minimum is 10Mbps, while 0.1 is the
lowest value that can be set for Maximum.
The Hardware Acceleration tab (not available to legacy network adapters) enables
VMQ, IPsec, and SR-IOV by selecting the appropriate check box. Remember that even
if these properties are set in a virtual machine, it does not guarantee their use. For
example, if the physical network adapter does not support VMQ or has run out of
VMQs, then VMQ will not be used for the vmNIC. Likewise, if SR-IOV is selected by
the virtual switch, if the hardware does not support SR-IOV, or if the physical adapter
has no more available virtual functions, then SR-IOV will not be used. Selecting the
options simply enables the capabilities to be used if they are available, without
guaranteeing their actual use.
The Advanced Features tab enables interesting options whose use will vary depending
on the environment deploying the technology:
MAC Address By default, a dynamic MAC address is used, which is configured
when the VM is created and should not change. However, it’s also possible to select
Static and configure your own preferred MAC address. The option to enable MAC
address spoofing can also be set, which enables the VM to change the MAC address
