Promiscuous Mode Policy Change

[SCharchouf]

I'm using the below script to get Promiscuous Mode then I set it to desired value, I need assistance in order to create a script that can:

1. First get Promiscuous Mode
2. identify ESXi that have wrong configuration
3. set configuration to desired value

$ESXs=get-vmhost

$ESXs | % {
$esx=$_ ; $switchs= Get-VirtualSwitch $esx
$switchs | % { $switch=$_ ; $sec=Get-SecurityPolicy $switch ; `
"$esx $switch $($sec.AllowPromiscuous) $($sec.ForgedTransmits) $($sec.MacChanges)" >> $file_before}
}

$ESXs | Get-VirtualSwitch | Get-SecurityPolicy | Set-SecurityPolicy `
-MacChanges $false `
-ForgedTransmits $false `
-AllowPromiscuous $false

$ESXs | % {
$esx=$_ ; $switchs= Get-VirtualSwitch $esx
$switchs | % { $switch=$_ ; $sec=Get-SecurityPolicy $switch ; `
"$esx $switch $($sec.AllowPromiscuous) $($sec.ForgedTransmits) $($sec.MacChanges)" >> $file_after }
}

Try something like this.

It works for VSS and VDS.

$newVSSPolicy = @{

    VirtualSwitchPolicy = $null

    AllowPromiscuous = $false

    MacChanges = $false

    ForgedTransmits = $false

    Confirm = $false

  }

  $newVDSPolicy = @{

    Policy = $null

    AllowPromiscuous = $false

    MacChanges = $false

    ForgedTransmits = $false

    Confirm = $false

  }

  $reportBefore = @()

  $reportAfter = @()

  Get-VMHost -PipelineVariable esx |

  ForEach-Object -Process {

    # VSS

    Get-VirtualSwitch -Standard -VMHost $esx -PipelineVariable vss |

    Get-SecurityPolicy -PipelineVariable policy |

    where{$_.AllowPromicious -or $_.MacChanges -or $_.ForgedTransmits} |

    ForEach-Object -Process {

        $reportBefore += New-Object -TypeName PSObject -Property @{

            VMHost = $esx.Name

            Switch = $vss.Name

            AllowPromicious = $policy.AllowPromiscuous

            MacChanges = $policy.MacChanges

            ForgedTransmits = $policy.ForgedTransmits

        }

        $newVSSPolicy.VirtualSwitchPolicy = $policy

        Set-SecurityPolicy @newVSSPolicy

        Get-SecurityPolicy -VirtualSwitch $vss |

        ForEach-Object -Process {

            $reportAfter += New-Object -TypeName PSObject -Property @{

                VMHost = $esx.Name

                Switch = $vss.Name

                AllowPromicious = $_.AllowPromiscuous

                MacChanges = $_.MacChanges

                ForgedTransmits = $_.ForgedTransmits

            }

        }

    }

    # VDS

    Get-VDSwitch -VMHost $esx -PipelineVariable vds |

    Get-VDSecurityPolicy -PipelineVariable policy |

    where{$_.AllowPromicious -or $_.MacChanges -or $_.ForgedTransmits} |

    ForEach-Object -Process {

        $reportBefore += New-Object -TypeName PSObject -Property @{

            VMHost = $esx.Name

            Switch = $vds.Name

            AllowPromicious = $policy.AllowPromiscuous

            MacChanges = $policy.MacChanges

            ForgedTransmits = $policy.ForgedTransmits

        }

        $newVDSPolicy.Policy = $policy

        Set-VDSecurityPolicy @$newVDSPolicy

        Get-VDSecurityPolicy -VDSwitch $vds |

        ForEach-Object -Process {

            $reportAfter += New-Object -TypeName PSObject -Property @{

                VMHost = $esx.Name

                Switch = $vds.Name

                AllowPromicious = $_.AllowPromiscuous

                MacChanges = $_.MacChanges

                ForgedTransmits = $_.ForgedTransmits

            }

        }

    }

  }

  $reportBefore | Export-Csv -Path .\report-before.csv -NoTypeInformation -UseCulture

  $reportAfter | Export-Csv -Path .\report-after.csv -NoTypeInformation -UseCulture

There was some code in there that I forgot to remove.
Code is updated

[SCharchouf]

thanks there's no error now but both csv file are empty

[LucD]

There was another typo in the code, which I just corrected.

If none of the switches has an incorrect setting, the CSV files will be empty.
That is exactly what your request seems to ask for.
