In a Hyper-V environment, VLANs (Virtual Local Area Networks) are used to create multiple logical networks within the same physical network, enabling network isolation and improving management flexibility. Hyper-V's VLAN feature allows you to assign VLAN IDs to VMs, enabling them to communicate with other devices in the same VLAN while isolating them from devices in different VLANs. This configuration improves network security and manageability, ensuring that virtual machines operate independently on the same physical network without interfering with each other.
How to configure VLANs for Hyper-V Virtual Switches?
Hyper-V Virtual Switches are virtual switches used to connect VMs to the physical network and other virtual machines in a Hyper-V environment. They manage network communication between VMs and VM connectivity to external networks. By configuring VLANs on virtual switches, you can provide VLAN identification and isolation for virtual machines, ensuring that network traffic is properly isolated and managed in the virtual environment.
1. Select a Virtual Switch
Click Virtual Switch Manager > select the switch you want to configure
2. Configure VLAN identification
In Virtual Switch Properties, check Enable virtual LAN identification for management operating system > set a unique VLAN identifier (e.g., 2) for network communication. When finished, click OK to save your changes.
How to configure VLANs for Hyper-V VMs?
1. Select the Virtual Machine
Right-click the VM > Settings
2. Check Network Adapter Connections
Click Network Adapter to ensure that the network adapter is connected to the correct virtual switch.
3. Enable and Configure Hyper-V VLAN Tagging
Check Enable virtual LAN identification > enter the same VLAN ID (e.g., 2) as before.
In this way, all network traffic transmitted through the physical network adapters connected to this virtual switch will be tagged using this VLAN ID.
4. Finally, click OK to save the settings.

Hyper-V VLAN FAQs
Q1: Can I use multiple VLANs on a single virtual switch?
A1: Yes, you can configure a single virtual switch to handle multiple VLANs by enabling VLAN ID tagging and specifying different VLAN IDs for each VM or port group.
Q2: What happens if I forget to configure VLAN tagging on a virtual switch?
A2: If VLAN tagging is not configured correctly, VMs might not be able to communicate properly with the intended VLAN segments, leading to connectivity issues.
