Observed IP Ranges

[LittleOne]

Hey Guys,

I need some help to modify a script I found here. Basically i need to obtain esxi server name, not the vmhostid and if its posible add a column with the cluster name,

Thanks in advance!

Fer

This is the output i obtain with the below script

VMHostId                                  Device                         IPSubnet                                               Vlan

HostSystem-host-52823           vmnic0                         xxx.xxx.34.128-xxx.xxx.34.254                             934

I hope someone can help me.

function Get-ObservedIPRange {

[CmdletBinding()]
param(
[Parameter(Mandatory=$true,ValueFromPipeline=$true,ValueFromPipelineByPropertyName=$True,HelpMessage=”Physical NIC from Get-VMHostNetworkAdapter”)]
[Object[]]$Nics

)

process {

forEach ($Nic in $Nics)
{

if($Nic -notlike “vmk*”)
{
[VMware.VimAutomation.Client20.Host.NIC.PhysicalNicImpl]$NicImpl = $Nic
$hostView = Get-VMHost -Id $NicImpl.VMHostId | Get-View -Property ConfigManager
$ns = Get-View $hostView.ConfigManager.NetworkSystem
$hints = $ns.QueryNetworkHint($NicImpl.Name)

foreach ($hint in $hints)
{
if( ($hint.ConnectedSwitchPort) )
{
foreach ($subnet in $hint.subnet)
{
$observed = New-Object -TypeName PSObject
$observed | Add-Member -MemberType NoteProperty -Name Device -Value $NicImpl.Name
$observed | Add-Member -MemberType NoteProperty -Name VMHostId -Value $NicImpl.VMHostId
$observed | Add-Member -MemberType NoteProperty -Name IPSubnet -Value $subnet.IPSubnet
$observed | Add-Member -MemberType NoteProperty -Name VlanId -Value $subnet.VlanId
Write-Output $observed
}
}
}

}

}
}

}

Try like this

function Get-ObservedIPRange {

    [CmdletBinding()]

    param(

    [Parameter(Mandatory=$true,ValueFromPipeline=$true,ValueFromPipelineByPropertyName=$True,HelpMessage=”Physical NIC from Get-VMHostNetworkAdapter”)]

    [Object[]]$Nics

    )

    process {

        forEach ($Nic in $Nics){

            if($Nic -notlike “vmk*”){

                [VMware.VimAutomation.Client20.Host.NIC.PhysicalNicImpl]$NicImpl = $Nic

                $esx = Get-VMHost -Id $NicImpl.VMHostId

                $ns = Get-View $esx.ExtensionData.ConfigManager.NetworkSystem

                $hints = $ns.QueryNetworkHint($NicImpl.Name)

                foreach ($hint in $hints){

                    if( ($hint.ConnectedSwitchPort)){

                       foreach ($subnet in $hint.subnet){

                           $observed = New-Object -TypeName PSObject

                           $observed | Add-Member -MemberType NoteProperty -Name Device -Value $NicImpl.Name

                           $observed | Add-Member -MemberType NoteProperty -Name VMHost-Value $esx.Name

                           $observed | Add-Member -MemberType NoteProperty -Name IPSubnet -Value $subnet.IPSubnet

                           $observed | Add-Member -MemberType NoteProperty -Name VlanId -Value $subnet.VlanId

                           Write-Output $observed

                       }

                    }

                }

            }

        }

    }

}

Thanks a lot LucD!!!!

worksgreat.

whatwould I need to modify to have it show which vswitch the card is associated with?

[LucD]

Try like this.

Note it only supports VSS for now, not VDS

function Get-ObservedIPRange {

   [CmdletBinding()]

    param(

    [Parameter(Mandatory=$true,ValueFromPipeline=$true,ValueFromPipelineByPropertyName=$True,HelpMessage=”Physical NIC from Get-VMHostNetworkAdapter”)]

    [Object[]]$Nics

    )

    process {

        forEach ($Nic in $Nics){

            if($Nic -notlike “vmk*”){

                [VMware.VimAutomation.Client20.Host.NIC.PhysicalNicImpl]$NicImpl = $Nic

                $esx = Get-VMHost -Id $NicImpl.VMHostId

                $pnicTab = @{}

                $esx.ExtensionData.Config.Network.Pnic | %{

                    $pnicTab.Add($_.Key,$_.Device)

                }

                $switchTab = @{}

                $esx.ExtensionData.Config.Network.Vswitch | %{

                    $vss = $_.Name

                    $_.Pnic | %{

                        $switchTab.Add($pnicTab[$_],$vss)

                    }

                }

                $ns = Get-View $esx.ExtensionData.ConfigManager.NetworkSystem

                $hints = $ns.QueryNetworkHint($NicImpl.Name)

                foreach ($hint in $hints){

                    if( ($hint.ConnectedSwitchPort)){

                       foreach ($subnet in $hint.subnet){

                           $observed = New-Object -TypeName PSObject

                           $observed | Add-Member -MemberType NoteProperty -Name Device -Value $NicImpl.Name

                           $observed | Add-Member -MemberType NoteProperty -Name VMHost -Value $esx.Name

                           $observed | Add-Member -MemberType NoteProperty -Name VSS -Value $switchTab[$Nic.Name]

                           $observed | Add-Member -MemberType NoteProperty -Name IPSubnet -Value $subnet.IPSubnet

                           $observed | Add-Member -MemberType NoteProperty -Name VlanId -Value $subnet.VlanId

                           Write-Output $observed

                       }

                    }

                }

            }

        }

    }

}

I tried to implement your function in my scrip to obtain the IP subnet for vlan configured on physical NICs, but I kept getting no output.

When I verified the content of my variables, both at the main script and inside the function, my physical NICs object had correct data in them such as:

$NicImpl

Name       Mac               DhcpEnabled IP              SubnetMask      DeviceName

----       ---               ----------- --              ----------      ----------

vmnic3     xx:xx:xx:xx:xx:xx False                                           vmnic3

However the hints variable onside the Get-ObservedIPRange function had only Device Name, while subnet and Network have none, which explains why I got no output:

$hint

Device              : vmnic3

Subnet              :

Network             :

ConnectedSwitchPort : VMware.Vim.PhysicalNicCdpInfo

LldpInfo            :

I am wondering if there is any thing that changed on the powershell APIs in version ESX 6.5 build 8935087 that rendered the commands you used in your function Obsolete or Deprecated.

I suspect it might be an issue of CDP not being activated on the switches to which the pNICs are connected.

Do you see the data in the Web Client?
