Hyper-V-VmSwitch event 106

Question

Hi everybody,
I have a problem with my nic teaming in Hyper-V.
In eventlog I do have events with id 106:
Available processor sets of the underlying physical NICs belonging to the LBFO team NIC /DEVICE/{GUID} (Friendly Name: Microsoft Network Adapter Multiplexor Driver #2) on switch GUID (Friendly Name: HS-vSwitch) are not configured correctly. Reason: The processor sets overlap when LBFO is configured with sum-queue mode.
I have read the following blogs:

I do have 2 CPU-Sockets with 12 cores per socket and hyperthreading enabled.
That makes 48 logical processors.
My NIC-Team is switchindependent with "Hyper-V Port" load balancing mode.
As far as I understand I have to configure the VMQs to use seperate logical processors (lp) per NIC.
I do this with the following commands in powershell:
Set-NetAdapterVMQ –Name NIC01 –BaseProcessorNumber 0 –MaxProcessors 24
Set-NetAdapterVMQ –Name NIC02 –BaseProcessorNumber 24 –MaxProcessors 24
After this command I still get the error in eventlog :(
I tried a bit after that and used the following commands:
Set-NetAdapterVMQ –Name NIC01 –BaseProcessorNumber 0 –MaxProcessors 12
Set-NetAdapterVMQ –Name NIC02 –BaseProcessorNumber 24 –MaxProcessors 12
There should be no overlapping anymore but error is still there.
My NICs are VMQ enabled. This is verified with get-netadaptervmq and the above settings are correctly displayed (BaseVmqProcessor and MaxProcessors).
What am I getting wrong?
Thanks for your help.

Thanks for your reply.
The reboot didn't change anything. Would have been strange if the reboot would have been necessary :-)
I did some more testing and the following did solve my issue:
Set-NetAdapterVMQ -Name NIC1 -BaseProcessorgroup 0 –BaseProcessorNumber 2 -Enabled $True -MaxProcessorNumber 9 –MaxProcessors 8
Set-NetAdapterVMQ -Name NIC2 -BaseProcessorgroup 0 –BaseProcessorNumber 12 -Enabled $True -MaxProcessorNumber 19 –MaxProcessors 8
The additional parameters are listet as optional but in my case the were necessary.
Hope this helps someone to save some time.
