DISABLING NETFLOW WITH POWERCLI

Great script for viewing and disabling Vmware Netflow on a VDPortgroup, the below was a couple of quick and dirty scripts to first of all list all VDPortgroups and if they have Netflow enabled, the second was to disable Netflow for a VDPortgroup or a number of VDPortgroups.

This may help with a known issue on ESXi 5.1 when Netflow is enabled:http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2042370

List all VDPortGroups and if Netflow is enabled

Get-VDPortgroup | Select Name, VirtualSwitch, @{Name="NetflowEnabled";Expression={$_.Extensiondata.Config.defaultPortConfig.ipfixEnabled.Value}}




Function Disable-PGNetflow {

   [CmdletBinding()]

   Param (

      [Parameter(ValueFromPipeline=$true)]

      $DVPG

   )

   Process {

      Foreach ($PG in $DVPG) {

         $spec = New-Object VMware.Vim.DVPortgroupConfigSpec

         $spec.configversion = $PG.Extensiondata.Config.ConfigVersion

         $spec.defaultPortConfig = New-Object VMware.Vim.VMwareDVSPortSetting

         $spec.defaultPortConfig.ipfixEnabled = New-Object VMware.Vim.BoolPolicy

         $spec.defaultPortConfig.ipfixEnabled.inherited = $false

         $spec.defaultPortConfig.ipfixEnabled.value = $false

 

         $PGView = Get-View -Id $PG.Id

         $PGView.ReconfigureDVPortgroup_Task($spec)

      }

   }

}
