Uplink Ports
Uplink ports are ports associated with physical adapters, providing a connection between
a virtual network and a physical network. Physical adapters connect to uplink ports when
they are initialized by a device driver or when the teaming policies for virtual switches
are reconfigured.

Some virtual switches should not connect to a physical network and thus have no uplink
port, as shown in Figure 2. This is the case, for example, for a virtual switch that provides
connections between a firewall virtual machine and the virtual machines protected by the
firewall.
