Hyper-V VLAN networking

Hyper-V is a powerful virtualization platform built into Windows that allows users to create and manage virtual machines on their systems. Networking is a crucial aspect of virtualization, and Hyper-V provides a range of tools and features to help users manage network connections for their virtual machines.

In this article, we will look at how to get the MAC address, rename a network adapter, and set a VLAN on an adapter using Hyper-V.

Getting the MAC address of a network adapter

The MAC address is a unique identifier assigned to a network adapter that allows it to communicate on a network. To get the MAC address of a network adapter in Hyper-V, you can use the following PowerShell command:

Get-VM <VMName> | Get-VMNetworkAdapter | Select Name,MacAddress,IPAddresses

This command will retrieve the MAC address, name, and IP address of all the network adapters for the specified virtual machine.

Renaming a network adapter

To rename a network adapter in Hyper-V, you can use the following PowerShell command:

Get-VM <VMName> | Get-VMNetworkAdapter | ?{$_.MacAddress -eq '<MACAddress>'} | Rename-VMNetworkAdapter -NewName '<NewName>'

This command will find the network adapter with the specified MAC address and rename it with the new name. It is important to note that the MAC address must be in uppercase letters and separated by colons.

Setting VLANs on a network adapter Virtual LANs (VLANs) are used to partition a network into separate broadcast domains. Hyper-V allows users to set VLANs on network adapters to help manage network traffic for virtual machines.

Set VLANs on a network adapter

To set VLANs on a network adapter in Hyper-V, you can use the following PowerShell command:

Set-VMNetworkAdaptervlan -VMName <VMName> -VMNetworkAdapterName "<AdapterName>" -Trunk -AllowedVlanIdList "<VLANList>" -NativeVlanId <NativeVLAN>

This command will configure the specified network adapter to support VLANs. The -Trunk parameter indicates that the adapter is configured to allow traffic from multiple VLANs, while the -AllowedVlanIdList parameter specifies the list of VLANs allowed on the adapter.

The -NativeVlanId parameter specifies the VLAN that is untagged on the adapter. It is important to note that the native VLAN must be specified as a separate parameter and cannot be included in the allowed VLAN list.

Links to commands

To effectively use PowerShell commands in your virtual environment, it’s important to have access to all the parameters and information required to make the right choices. Fortunately, Microsoft has provided a wealth of resources on its website that can help:

In conclusion, Hyper-V provides a range of tools and features to help users manage network connections for their virtual machines. With these tools, users can efficiently manage their virtual networks and ensure optimal performance for their virtual machines.
