Windows Server Vlan Tagging

In this article we will show how to configure a tagged VLAN interface on Windows 10 and Windows Server 2016 (2019/2012R2). The VLAN (Virtual LAN) standard is described in IEEE 802.1Q standard and implies traffic tagging (vlanid) so that a network packet may be referred to a particular virtual network. VLANs are used to separate and segment networks, restrict broadcast domains and isolate network segments to improve security. In Windows, you can configure several different logical network interfaces with different VLANID in a single physical interface using different tools.

Setting up VLAN and Teaming on Server 2012, 2012R2 and 2016.

To use VLAN, you will have to configure the physical switch port, to which your computer/server is connected. The port must be switched from access mode to trunk mode. By default, all VLANs are allowed on the trunk port, but you can set the list of allowed VLAN numbers (1 to 4094) available at this Ethernet switch port.

Creating Multiple VLAN Interfaces on Windows 10

Windows desktop editions don’t natively support VLAN tagging. Only in the latest Windows 10 builds you can set one VLAN tag for a network adapter. To do it, a PowerShell cmdlet to manage network settings is used. For example:

Set-NetAdapter –Name 'Ethernet0' -VlanID 24

However, there are two ways to create a separate virtual interface with the specific VLAN ID in Windows 10: using a special driver and tool by your network adapter manufacturer or using Hyper-V.

Multiple VLANs on a Realtek NIC in Windows 10

For Realtek network cards you can configure multiple virtual network adapters with different VLANs using a special tool — Realtek Ethernet Diagnostic Utility. See the description on the manufacturer website to make sure that your Realtek network adapter supports VLAN configuration.

Download and install the latest network driver for your Realtek adapter and run the Ethernet Diagnostic Utility.

Go to the VLAN section, click Add and add the required VLAN ID. Then a new network connection will appear in Windows.

After creating network interfaces for your VLANs, you can assign them IP addresses from the corresponding IP subnet.

How to Setup VLAN on an Intel Ethernet Network Adapter?

To configure VLAN, Intel has its own tool — Intel Advanced Network (Intel® ANS) VLAN. Of course, your network adapter model must support VLAN (for example, VLAN is not supported for NICs such as Intel PRO/100 or PRO/1000). When you install a driver, select to install Intel PROSet for Windows Device Manager and Advanced Network Services.

Then a separate VLANs tab appears in the properties of your physical Intel network adapter, where you can create multiple VLAN interfaces.

However, this method works in all previous Windows versions (up than Windows 10 build 1809). In the newer Windows versions, the following message is displayed in the VLANs tab:

Recently, Intel has released an updated network adapter driver and Intel PROSet Adapter Configuration Utility for the latest Windows builds. Download and install the latest Intel driver version and the configuration tool.

Run it, open the Teaming/VLANs tab, click New and enter the name of your network interface and its VLANID.

Also, you can add/remove/view the list of VLANs using special PowerShell cmdlets from the IntelNetCmdlets module:

Get-IntelNetVLAN, Add-IntelNetVLAN

Multiple VLANs in Windows 10 Using Hyper-V Virtual Switch

There is another way to create multiple VLANs on Windows 10 using Hyper-V (it is available only in Pro and Enterprise). To use it, install Hyper-V components:

Enable-WindowsOptionalFeature -Online -FeatureName:Microsoft-Hyper-V -AllAir gear season 2 episode 1 corporation western cape.

Create a new virtual switch in the Hyper-V Manager or using PowerShell commands (see an example in the article on how to configure Hyper-V Server).

Then run the following commands for each VLAN you want to create:

Add-VMNetworkAdapter -ManagementOS -Name VLAN24 -StaticMacAddress “11-11-AA-BB-CC-DD” -SwitchName vSwitch2
Set-VMNetworkAdapterVlan -ManagementOS -VMNetworkAdapterName VLAN24 -Access -VlanId 24

So a network adapter with the VLAN you want will appear in Windows.

How to Configure Multiple VLANs in Windows Server 2016?

In Windows Server 2016, you can configure VLAN using built-in tools, you don’t need to install any special drivers or utilities. Let’s try to configure some different VLANs on a single physical network adapter on Windows Server 2016 using NIC Teaming.

Make sure that no VLAN number is set in the network adapter advanced settings (VLAN ID = 0).
  1. Start Server Manager -> Local and click the NIC Teaming link;
  2. In the Teams section, click Task -> New Team. Specify the group name and select network adapters to add;
    You can create a NIC Teaming group using PowerShell:
    New-NetLbfoTeam -Name vTeam -TeamMembers 'Ethernet1','Ethernet2' -TeamingMode SwitchIndependent -LoadBalancingAlgorithm Dynamic
  3. Then in the “Adapter and Interfaces” section, add virtual network interfaces. Click Tasks -> Add Interface;
  4. Enter the name of the interface you are going to create and a VLAN number;
    You can add a network interface and set a VLAN for it in PowerShell:
    Add-NetLbfoTeamNic -Team vTeam -VlanID 24 -Name VLAN24
  5. In the same way you can add as many VLAN network interfaces as you need;
  6. Then configure the IP settings of all virtual network interfaces you created in ncpa.cpl.

The magic word is… VlanFiltering. But more on that later…

I’m working on setting up a new Hyper-V cluster at work, and it has been a slow process. Not because of the technology, but rather because I’m lucky if I get 10 minutes a day to work on it. Everyday I go into work thinking, “Today’s the day! I’m going to shut my door, close Outlook, and get it done!” Fast forward eight (or nine… or more) hours, and there I am leaving the office thinking “Maybe tomorrow.” Projects tend to drag on when you’re getting pulled in fifty different directions. But I digress…

The important part to know is that I’m setting up a couple of Hyper-V hosts (Hyper-V Server 2012 R2 mind you, none of this Windows Server with the Hyper-V role for this guy), and I was setting up my logical switches via System Center Virtual Machine Manager 2012 R2 (VMM). I’ll skip over the issue I ran into with the Management switch and virtual adapter and save that for another day. Once I worked around that problem, I was ready to add my converged switch. The converged switch sits atop a team of two dual-port Broadcom BCM57810 10 GigE NICs. That team connects to a Port Channel on a Cisco Nexus 5000 which is trunking several VLANs including my Live Migration and Cluster CSV networks for the host as well as iSCSI and client VLANs for my guests. I added the logical switches, hit OK, and watched as everything was configured on the hosts.

It was a grand success. Except for the part where I couldn’t pass traffic between the hosts on any of the VLANs. It became clear that the VLAN tags on the traffic were getting dropped and everything was dumped on the default VLAN. I spent the next week poking around, trying to figure out what would cause this problem with little success. I can’t count the number of times I would add the switch, tear it down, add it again, and so on. Online searches weren’t bearing any fruit either. Nothing I found seemed the least bit relevant.

Enter Dinko Fabricni and his blog, IT Solution Braindumps. Back in 2012, Dinko posted an article, “VLAN tagging problems in Windows Server 2012 Hyper-V”, that described my problem and provided the solution for which I had been hunting. It turns out my Broadcom 10 GigE NICs (but not my 1 GigE NICs) were set to filter VLANs by default. To get them to pass the VLAN tags I had to add a registry key to each adapter.

The fix is to add the registry value VlanFiltering (type DWORD) to the following location and set it to 0.

where xx is the number for the NIC in question. There are a lot of registry keys under that GUID, so make sure you find all of your NICs because you will need to change it on every NIC in the team. Make that change and restart, and it all starts working. It did for me at least.

Windows Dhcp Server Vlan Tagging

This isn’t a new setting. Searching on the term shows references to it going back years, but it was never something I needed to set before. I expect that is probably because now I’m using the native NIC teaming that was introduced in Server 2012. Before I was using the Broadcom utilities to configure teams and VLANs, and I guess it was taking care of that setting itself.

So let me thank Dinko Fabricni and his blog post for saving my sanity and getting me back on track to finish this project.
