PowerCLI: Host Networking Device info

In this post I will share a simple PowerCLI script which generates some Network Device information from your vSphere hosts. The information you’ll get is the vmHost name, device name, linkspeed and MAC address.

$vmHostNicInfo = @()
foreach($vmHost in (Get-VMHost | Sort Name)){
    foreach($nic in $vmhost.NetworkInfo.PhysicalNic){ 
        $Details = "" | Select vmHost, Device,Linkspeed,Mac

        $Details.vmHost = $vmhost.Name
        $Details.Device = $nic.Extensiondata.Device
        $Details.Linkspeed = ($nic.Extensiondata.Linkspeed).SpeedMB
        $Details.Mac = $nic.Extensiondata.Mac
    
        $vmHostNicInfo += $Details
    }
}
$vmHostNicInfo | Format-Table -AutoSize

The output will look like this:

But what if you only want to see the devices with a link speed lower then 1000? Well that’s possible with the following end line:

$vmHostNicInfo | Where {$_.Linkspeed -lt "1000"} |  Format-Table -AutoSize

Or if you want to know which device/host belongs to a particular MAC address. You can use the following end line:

$vmHostNicInfo | Where {$_.Mac -eq "00:07:e9:1f:f9:bf"} |  Format-Table -AutoSize

So with a small script, you’re able to export valuable data.
