I have a two host clustered HyperV environment and Im trying to add a second, VLAN 12 for isolated traffic. The virtual switch is external with OS management and is not tagged. My production VM are untagged and traffic is flowing the new VM that will be isolated is tagged and traffic is not flowing. I was told that a hyperv switch can only be tagged with two VLANs, if so how would I add another VLAN since the GUI only allows one VLAN.
The physical switch is configured to all untagged traffic to assign VLAN 10 and tagged for VLAN 12.
How do I get this to work?
