VMware: Add PortGroup to all hosts in cluster with PowerCLI

Today we configured a new VLAN on the physical switches, now we need to
configure a portgroup with vlan id on multiple ESX hosts in our cluster. To do
this by hand it will cost 3 minutes per host, to script this.. you configure
this in 10 seconds!
The script:
Get-Cluster “clustername” | Get-VMHost | Get-VirtualSwitch -Name
“vSwitch0″ | New-VirtualPortGroup -Name “VLAN-23-Citrix Provisioning” -VLanId
