This is the script that I use when I need to add several new port groups to a single VMware cluster. The script does check for the port group before it tries to add it to the VMhost encase it was already setup.
$NetworkInfo = Import-CSV C:\scripts\logs\NetworkInfo.csv
$ClusterName = "VM_Cluster"
$VMHosts = Get-Cluster $ClusterName | Get-VMHost
Foreach ($network in $NetworkInfo){
$NewPortSwitch = $network.NewPortSwitch
$VLANID = $Network.VLANID
Foreach ($VMHost in $VMHosts){
IF (($VMHost | Get-VirtualPortGroup -name $NewPortSwitch -ErrorAction SilentlyContinue) -eq $null){
Write-host "Creating $NewPortSwitch on VMhost $VMHost" -ForegroundColor Yellow
$NEWPortGroup = $VMhost | Get-VirtualSwitch | Select -last 1 | New-VirtualPortGroup -Name $NewPortSwitch -VLanId $VLANID
}
}
}
Below is the format for the NetworkInfo.csv. You can add as many port groups as you need in to this file and it gets feed into the script.

Hey Stuart – I just used this script to duplicate network settings on a new vCenter v6.7 cluster I’m building. It worked great, but it needed a minor tweak since we have multiple vSwitches on each host due to iSCSI storage. See below…
$NetworkInfo = Import-CSV C:\scripts\logs\NetworkInfo.csv
$ClusterName = “VM_Cluster”
$VMHosts = Get-Cluster $ClusterName | Get-VMHost
Foreach ($network in $NetworkInfo){
$NewPortSwitch = $network.NewPortSwitch
$VLANID = $Network.VLANID
Foreach ($VMHost in $VMHosts){
IF (($VMHost | Get-VirtualPortGroup -name $NewPortSwitch -ErrorAction SilentlyContinue) -eq $null){
Write-host “Creating $NewPortSwitch on VMhost $VMHost” -ForegroundColor Yellow
$NEWPortGroup = $VMhost | Get-VirtualSwitch -Name “vSwitch0” | Select -last 1 | New-VirtualPortGroup -Name $NewPortSwitch -VLanId $VLANID
}
}
}
Hello Tim,
Thanks for the update to the script. We have a plan to get the work environment up to 6.7u1, but it might still be some time before we get it completed.

The upgrade isn’t too bad. If you use the VCSA it makes it almost painless. I could walk you through it over the phone if you want to. I learned from a couple of mistakes that I wouldn’t want you to repeat. Nothing horrible, but I rebuilt a host that I could have just had the VCSA automagically update.
