Observed IP Ranges

[alanrenouf]

Hi,

Is it possible to get the 'Observed IP Ranges' for each nic in each host, couldnt find where it was recorded ?!

Thanks

It's located in ipSubnet property of the PhysicalNicIpHint. You can get PhysicalNicIpHint object from HostNetworkSystem.QueryNetworkHint()

$h = Get-VMHost | Get-View
$networkSystem = Get-View $h.ConfigManager.NetworkSystem
$networkSystem.NetworkConfig.Pnic | %{$networkSystem.QueryNetworkHint($_.device)} |%{$_.Subnet}

Regards,

Yasen

Thanks, Unfortunatly Im getting the following error:

Get-View : The argument cannot be null or empty.<br /><br/>

+ $networkSystem = Get-View  &lt;&lt;&lt;&lt; $h.ConfigManager.NetworkSystem<br/><br/>

When you have more than 1 ESX server the script becomes a bit more complex.

Try this:

$networkSystem = Get-VMHost | Get-View | %{Get-View $_.ConfigManager.NetworkSystem}
foreach($netSys in $networkSystem){
  foreach($pnic in $netSys.NetworkConfig.Pnic){
    $subnets = $netSys.QueryNetworkHint($pnic.Device)
    foreach($pnicHint in $subnets){
	  Write-Host $pnicHint.Device
	  foreach($pnicIpHint in $pnicHint.Subnet){
	    Write-Host "`t" $pnicIpHint.IpSubnet
	  }
	}
  }
}

Amazing as always LucD

Thanks.

It's probably useful to list the ESX hostname as well.

$esxList = Get-VMHost | Get-View
foreach($esx in $esxList){
	Write-Host $esx.Name
	$networkSystem = Get-View $esx.ConfigManager.NetworkSystem
	foreach($netSys in $networkSystem){
		foreach($pnic in $netSys.NetworkConfig.Pnic){
			Write-Host 
			$subnets = $netSys.QueryNetworkHint($pnic.Device)
			foreach($pnichint in $subnets){
				Write-Host "`t" $pnichint.Device
				foreach($pniciphint in $pnichint.Subnet){
					Write-Host "`t`t" $pniciphint.IpSubnet
				}
			}
		}
	}
}

ha ha snap !

$vmhosts = Get-VMHost | Get-View 
foreach ($vmhost in $vmhosts)
{
	$networkSystem = Get-view $vmhost.ConfigManager.NetworkSystem
	Write-Host $vmhost.Name -foregroundcolor yellow
	foreach($netSys in $networkSystem)
	{
		foreach($pnic in $netSys.NetworkConfig.Pnic)
		{
			$subnets = $netSys.QueryNetworkHint($pnic.Device)
			foreach($pnicHint in $subnets)
			{
				Write-Host $pnicHint.Device
				foreach($pnicIpHint in $pnicHint.Subnet)
				{
					Write-Host "`t" $pnicIpHint.IpSubnet
				}
			}
		}
	}
}

Scary, the twilight zone

Du du du du, Du du du du (sounded better in my head !)

Ok, just had a request to add the Cisco Discovery Protocol Info, any ideas where the info is stored ?

Thanks LucD Didnt search for that one
