I should configure 3 vSwitches in Hyper-V. I'm able to define the VLAN inside a VM directly.
Bud instead of giving each Vm a VLAN Id I would like create 3 vSwitche with the VLAN ID. So I do only need to assign the Switch to the VM. So I can avoid to assign individually to each VM (we have 70 VM's) the VLAN.
