Learning PowerCLI - Second Edition

Using standard port groups

Port groups are collections of ports that have the same properties, such as the same virtual switch, VLAN ID, Teaming policy, policies for filtering, tagging, and traffic shaping. Port groups are identified by a network label name. You should give all port groups in a data center, which are connected to the same network, the same network label. This will make virtual machine configurations portable across hosts. Using the PowerCLI cmdlets, you can only specify a network label name for the port group and a VLAN ID.
