get switch

[antoniogemelli]

Hello, I use this script to get some network adapter information, I would like to get also switch too,

Get-VMHostNetworkAdapter |
Where-Object {$_.GetType().Name -eq "PhysicalNicImpl"} |
Select-Object -Property VMHost,Name,BitRatePerSec,FullDuplex,Mac,DhcpEnabled,
  @{Name="AutoNegotiate";Expression={
    if ($_.ExtensionData.Spec.LinkSpeed)
      {$false} else {$true}
  }},
  @{Name="LinkState";Expression={
    if ($_.ExtensionData.LinkSpeed)
     {"Up"} else {"Down"}
  }} | Export-Csv -Path C:\Users\gemela\info.csv -NoTypeInformation -UseCulture

Thanks

Try something like this

Get-VMHostNetworkAdapter -Physical |

Select-Object -Property VMHost,Name,BitRatePerSec,FullDuplex,Mac,DhcpEnabled,

  @{Name="AutoNegotiate";Expression={

   if ($_.ExtensionData.Spec.LinkSpeed)

  {$false} else {$true}

  }},

  @{Name="LinkState";Expression={

   if ($_.ExtensionData.LinkSpeed)

  {"Up"} else {"Down"}

  }},

  @{N='vSwitch';E={

   $vnic = $_.Name

   Get-VirtualSwitch -VMHost $_.VMHost | where{$_.Nic -contains $vnic} | Select -ExpandProperty Name

  }}  | Export-Csv -Path C:\Users\gemela\info.csv -NoTypeInformation -UseCulture

vSwitch record are empty in the csv

[LucD]

Works for me, the vSwitch property is empty when the vmnic is not used in any vSwitch.
Are you using VSS or VDS, or a mix of both types?

[LucD · Accepted solution]

Ok, with VDS the vSwitch field is indeed blank.

Try this variation.

Get-VMHostNetworkAdapter -Physical |

Select-Object -Property VMHost,Name,BitRatePerSec,FullDuplex,Mac,DhcpEnabled,

  @{Name="AutoNegotiate";Expression={

   if ($_.ExtensionData.Spec.LinkSpeed)

  {$false} else {$true}

  }},

  @{Name="LinkState";Expression={

   if ($_.ExtensionData.LinkSpeed)

  {"Up"} else {"Down"}

  }},

  @{N='vSwitch';E={

   $vmnic = $_.Name

   $esxcli = Get-EsxCli -VMHost $_.VMHost

   $sw = @($esxcli.network.vswitch.standard.list() | where{$_.Uplinks -contains $vmNic} | select -ExpandProperty Name)

   $sw += $esxcli.network.vswitch.dvs.vmware.list() | where{$_.Uplinks -contains $vmNic} | select -ExpandProperty Name

   $sw -join '|'}}

This is perfect, thanks LucD.

Hi LucD,

One more question, Is possible to group the result? or get name of hardware? (one more column),

It will be useful if I can recognize which Nic is part of Broadcom 10/20 Gigabit Ethernet and which Nic are part of Intel...

Thanks a lot.

Try like this

Get-VMHostNetworkAdapter -Physical |

Select-Object -Property VMHost,Name,BitRatePerSec,FullDuplex,Mac,DhcpEnabled,

  @{Name="AutoNegotiate";Expression={

   if ($_.ExtensionData.Spec.LinkSpeed)

  {$false} else {$true}

  }},

  @{Name="LinkState";Expression={

   if ($_.ExtensionData.LinkSpeed)

  {"Up"} else {"Down"}

  }},

  @{N='vSwitch';E={

   $script:vmnic = $_.Name

   $script:esxcli = Get-EsxCli -VMHost $_.VMHost

   $sw = @($esxcli.network.vswitch.standard.list() | where{$_.Uplinks -contains $vmNic} | select -ExpandProperty Name)

   $sw += $esxcli.network.vswitch.dvs.vmware.list() | where{$_.Uplinks -contains $vmNic} | select -ExpandProperty Name

   $sw -join '|'}},

  @{N='HW';E={

   $script:esxcli.network.nic.list() | where{$_.Name -eq $script:vmnic} | select -ExpandProperty Description}}

Amazing, thanks LucD 🙂
