Create 80 DvPG with less than x Ports Free.ps1

The plugin checks the port groups of the Distributed vSwitches in the environment for the amount of ports which are currently free.
 
Uplinks and ephemeral port groups are left out for the obvious reasons.
 
It does require PowerCLI 5.1 R2 to make use of the VDS cmdlets.
