Getting promiscuous mode working in Hyper-V

I am trying to get promiscuous mode working in a clustered Hyper-V environment. The host server is running Windows 2012 Server R2. Below I have the PowerShell command and the results that I get back.

Command:

$portFeature=Get-VMSystemSwitchExtensionPortFeature -FeatureName "Port Mirroring" 
$portFeature.SettingsData.MonitorMode = 2 Add-VMSwitchExtensionPortFeature -ExternalPort -SwitchName "MySwitch" -VMSwitchExtensionFeature $portFeature

Open in new window

Results:

Get-VMSystemSwitchExtensionPortFeature : A positional parameter cannot be found that accepts argument '$null'.
At line:1 char:14
+ $portFeature=Get-VMSystemSwitchExtensionPortFeature -FeatureName "Port Mirroring ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Get-VMSystemSwitchExtensionPortFeature], ParameterBindingException
    + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.HyperV.PowerShell.Commands.GetVMSystemSwitchExtens
   ionPortFeatureCommand

Open in new window

Can anyone tell me what I am doing wrong with my command? The ultimate goal is to enable promiscuous mode on a single NIC so it can be used for Network monitoring. I will then map that single NIC to a virtual machine.

Philip,

Thank you for the information that you have sent me. I have been spending the morning reviewing it. I am trying to fully understand the commands before I run them in our production environment. It appears, that I was specifying the wrong “-FeatureName”.

I will continue working on this and will update this posting.

Many Thanks!
