Azure Stack HCI - Network configuration design with SDN

Hello,

May I have a question related to vswitches? You wrote above:

"We can add both the compute and management networks to the same virtual switch (SET vSwitch). Alternately, we could keep them in separate intents.  A virtual switch has to have the Virtual Filtering Platform (VFP) extension activated in order to be compatible with SLB. "

In my test environment I deployed two vswitches. One for management and one for compute. I activated VFP on both switches. After that I got a message on the SDN deployment panel in WAC saying that activated VFP on more the one vswitch in unsupported.  If I turn off the VFP on the compute switch, VMs on different Host in the same Virtual Network (VXLAN) cannot communicate with each other.

I tried to look for documentation on the net, but found nothing. 

Could you please help me why is this warning message? Where can I find the right documentation?

Thanks,

Ákos
