PowerCLI: Get-VirtualPortgroup -Distributed VlandId value is empty

Today I was busy with PowerCLI and dvPort groups.  I started to use the Get-VirtualPortgroup –Distributed cmdlet and parameter to retrieve some information about the dvPort group. But the default output doesn’t show the VlanId. See the screen shot below for the default output.

I don’t know if this is a known issue between PowerCLI 5.1 release 1 and vSphere 4.1 update 2. So I have to test it in a vSphere 5 environment.

But how can you find the vlanid of a distributed portgroup? You can use a PowerCLI script which I created  to fix this little “bug” and I have also added the PortsFree column to the output of the script.

$dvPortgroup = get-virtualportgroup -Distributed -Name "vlan1"
$dvPortgroupInfo = New-Object PSObject -Property @{            
    Name = $dvPortgroup.Name
    Key = $dvPortgroup.Key
    VlanId = $dvPortgroup.ExtensionData.Config.DefaultPortConfig.Vlan.VlanId
    Portbinding = $dvPortgroup.Portbinding
    NumPorts = $dvPortgroup.NumPorts
    PortsFree = ($dvPortgroup.ExtensionData.PortKeys.count - $dvPortgroup.ExtensionData.vm.count)
}  
$dvPortgroupInfo | ft -AutoSize

The output of the script:

If you want to create a report of all the dvPort groups. You can use the following script to achieve that goal:

$info = @()
foreach($dvPortgroup in (Get-VirtualPortgroup -Distributed | Sort Name)){
    $dvPortgroupInfo = New-Object PSObject -Property @{            
        Name = $dvPortgroup.Name
        Key = $dvPortgroup.Key
        VlanId = $dvPortgroup.ExtensionData.Config.DefaultPortConfig.Vlan.VlanId
        Portbinding = $dvPortgroup.Portbinding
        NumPorts = $dvPortgroup.NumPorts
        PortsFree = ($dvPortgroup.ExtensionData.PortKeys.count - $dvPortgroup.ExtensionData.vm.count)
    }  
    $info += $dvPortgroupInfo
}
$info | Export-Csv -UseCulture -NoTypeInformation C:\tmp\dvportgroup_info.csv
