PowerCLI - Generating A Network Configuration Report

I needed to generate a report from my vSphere environment to detail the network configurations of my various Hosts including the DataCenter and Cluster that the Hosts belong to, as well as vSwitch configs, any active and standby NICs that were assigned, port group name, VLAN ID, device type (ie vmk port) and any IP assigned. I also wanted to export this information to CSV.

I did this is two parts.

1. Host to Cluster and DataCenter;
Get-VMHost | Select Name, @{N=”Cluster”;E={Get-Cluster -VMHost $_}},@{N=”Datacenter”;E={Get-Datacenter -VMHost $_}} | Export-csv c:\temp\inventory.csv

2. Network configuration info;
&{foreach($esx in Get-VMHost){
    $vNicTab = @{}
    $esx.ExtensionData.Config.Network.Vnic | %{
        $vNicTab.Add($_.Portgroup,$_)
    }
    foreach($vsw in (Get-VirtualSwitch -VMHost $esx)){
        foreach($pg in (Get-VirtualPortGroup -VirtualSwitch $vsw)){
            Select -InputObject $pg -Property @{N="ESX";E={$esx.name}},
                @{N="vSwitch";E={$vsw.Name}},
                @{N="Active NIC";E={[string]::Join(',',$vsw.ExtensionData.Spec.Policy.NicTeaming.NicOrder.ActiveNic)}},
                @{N="Standby NIC";E={[string]::Join(',',$vsw.ExtensionData.Spec.Policy.NicTeaming.NicOrder.StandbyNic)}},
                @{N="Portgroup";E={$pg.Name}},
                @{N="VLAN";E={$pg.VLanId}},
                @{N="Device";E={if($vNicTab.ContainsKey($pg.Name)){$vNicTab[$pg.Name].Device}}},
                @{N="IP";E={if($vNicTab.ContainsKey($pg.Name)){$vNicTab[$pg.Name].Spec.Ip.IpAddress}}}
        }
    }
}} | Export-Csv "c:\temp\report.csv" -NoTypeInformation -UseCulture
