Two Virtual Switches on one physical interface - hyper-v 2019 core.

Question

Two Virtual Switches on one physical interface - hyper-v 2019 core.

Hi everyone,

As I mentioned in a title, we're looking for some specific solution.

We'd like to share one physical interface in our host between two virtual switches which would have other vlan's ranges. First 1-2000 and the second 2001-4096.

Now we've got one physical interface (lacp on two sfp+), one vmswitch (1-4096 vlans) and few virtual interfaces (every has it's own vlan).

So instead of a one vmswitch should be two switches (first 1-2000, second 2001-4096)

Two switches are not needed to accomplish what you are asking for. When you connect a VM to an External Virtual Switch (i.e. a virtual switch defined to a physical NIC), you connect that VM via a virtual NIC connected to the virtual switch. Simply define the virtual NIC on the VM to have the VLANs you want. A single NIC can have multiple VNICs each with different VLAN definitions.

Hi,
You don't need two swithes as you set VLAN IDs in virtual NICs on VMs, not in virtual switches. In virtual switches you can only set VLAN for the Hyper-V host.

Any way to do this without putting them on different VLANs? I believe this is what the user wanted to do (as do I). On separate VLANs, it's difficult to do simulations (especially when you wish to have VMs all on the same page - say for testing)
