Explanation

Configuring virtual local area networks (VLANs) All released versions of Hyper-V support virtual local area networks (VLANs). A VLAN configuration is software-based, which means that you can easily move a computer and still maintain their network configurations. For each virtual network adapter you connect to a virtual machine, you can configure a VLAN ID for the virtual machine. You will need the following to configure VLANs: A physical network adapter that supports VLANs. A physical network adapter that supports network packets with VLAN IDs that are already On the management operating system, you will need to configure the virtual network to allow network traffic on the physical port. This is for the VLAN IDs that you want to use internally with virtual machines. Next, you configure the virtual machine to specify the virtual LAN that the virtual machine will use for all network communications. There are two modes in which you can configure a VLAN: access mode and trunk mode. In access mode, the external port of the virtual network is restricted to a single VLAN ID in the UI. You can have multiple VLANs using WMI. Use access mode when the physical network adapter is connected to a port on the physical network switch that also is in access mode. To give a virtual machine external access on the virtual network that is in access mode, you must configure the virtual machine to use the same VLAN ID that is configured in the access mode of the virtual network. Trunk mode allows multiple VLAN IDs to share the connection between the physical network adapter and the physical network. To give virtual machines external access on the virtual network in multiple VLANs, you need to configure the port on the physical network to be in trunk mode. You will also need to know the specific VLANs that are used and all of the VLAN IDs used by the virtual machines that the virtual network supports.
