Physical NIC MAC Address

[timrcase]

Can you get the MAC address for your physical NICs using the PowerShell toolkit?

Yes, it's buried deep inside of the object returned by Get-VMHostNetwork.

PS > Get-VMHost | Get-VMHostNetwork | select -expandProperty PhysicalNic | format-list *


BitRatePerSec      : 100
FullDuplex         : True
WakeOnLanSupported : True
Id                 : key-vim.host.PhysicalNic-vmnic0
DeviceName         : vmnic0
Mac                : 00:c0:9f:3a:64:6a
DhcpEnabled        : False
IP                 :
SubnetMask         :

How about the flipside - Can I identify a VM if I only have the MAC address?

[LucD]

Something like this should do the trick.

$tgtMAC = "00:50:56:b3:30:38"
$vms = Get-VM
foreach($vm in $vms){
  $vmMAC = $vm | Get-NetworkAdapter | select MacAddress
  foreach($mac in $vmMAC){
    if($mac.MacAddress -eq $tgtMAC) {
	  Write-Host $vm.Name
	}
  }
}

great stuff!!!

I have two hosts and each has two NICs. I get the following error:

Get-VMHostNetwork : Index was outside the bounds of the array.
At line:1 char:31
+ Get-VMHost | Get-VMHostNetwork <<<<  | select -expandProperty PhysicalNic | f
ormat-list *
    + CategoryInfo          : NotSpecified: (:) [Get-VMHostNetwork], IndexOutO
   fRangeException
    + FullyQualifiedErrorId : System.IndexOutOfRangeException,VMware.VimAutoma
   tion.Commands.Host.GetVmHostNetwork

I'm really after getting this information in a decent Xml format that relates the host name to the individual NICs. I've also tried this but it doesn't end up with a relationship between the host and the NICs.

Get-vmHost | %{Get-View $_.id} | %{$_.name $($_.config.network.pnic | %{$_.device, $_.mac})}

I used this follows script, however the results are not as they should be. I do not see a MAC address specified.

Get-VMHost | Get-VMHostNetwork | select -expandProperty PhysicalNic | format-list *

Strange, the MAC property should be in there.

Which PowerCLI version are you running ?

Can you do a

Get-PowerCLIVersion

To search by MAC or IP, does it require VMware tools to be installed and running to report out that information? We have some Linux hosts without VMware tools so I am curious to know if they will not be included when searching for an IP.

[LucD]

The MAC can be found without the Tools installed, for the IP addr the Tools need to be installed.
