VMware PowerCLI

When you provide the VMHost and VirtualSwitch parameters on a call to Get-VirtualPortgroup, the cmdlet will return:

• all portgroups on the switch passed on the VirtualSwitch parameter

and

• all portgroups (VSS and VDS) on the ESXi node passed on the VMHost parameter

It looks as if both parameters are or-ed together, while the normal behaviour on PowerShell/PowerCLI cmdlets is to "and" parameters together.

Take for example the Get-Annotation cmdlet, where the Entity and CustomAttribute parameters are and-ed together.
