Port groups are not configured with a network label.

Port Groups define how virtual machine connections are made through the virtual switch. Port groups may be configured with bandwidth limitations and VLAN tagging policies for each member port. Multiple ports may be aggregated under port groups to provide a local point for virtual machines to connect to a network. The maximum number of port groups that may be configured on a virtual switch is 512. Each port group is identified by a network label and a VLAN ID. Network labels identify the port groups with a name. These names are important since they serve as a functional descriptor for the port group. Without these descriptions, identifying port groups and their functions becomes difficult as the network becomes more complex.
