Wake on LAN
Wake on LAN (WOL) is a feature that allows a system to be awakened from a sleep state by the arrival of a
specific packet over the Ethernet interface. Because a virtual adapter is implemented as a software only device,
it lacks the hardware features to implement Wake on LAN and cannot be enabled to wake the system from a
sleeping state via the virtual adapter. The physical adapters, however, support this property, even when the
adapter is part of a team.
Preboot Execution Environment (PXE)
The Preboot Execution Environment (PXE) allows a system to boot from an operating system image over the
network. By definition, PXE is invoked before an operating system is loaded, so there is no opportunity for the
BASP intermediate driver to load and enable a team. As a result, teaming is not supported as a PXE client,
though a physical adapter that participates in a team when the operating system is loaded may be used as a
PXE client. Whereas a teamed adapter cannot be used as a PXE client, it can be used for a PXE server, which
provides operating system images to PXE clients using a combination of Dynamic Host Control Protocol (DHCP)
and the Trivial File Transfer Protocol (TFTP). Both of these protocols operate over IP and are supported by all
teaming modes.
