Adding a network adapter

While it’s possible to create NICs in the Azure management portal, you can not attach them to VMs there. That can only be done using PowerShell. Make sure you have the latest version of Microsoft Azure PowerShell installed on your PC. The latest release can be installed using the Web Platform Installer.

The first step is to open Windows PowerShell ISE and log in to your Azure subscription using the Login-AzureRmAccount cmdlet. Define the following variables for the VM, network, and other parameters that will be required.

$vmName = ‘sw-sed-azure-01’
$vnetName = ‘AzureVNet1’
$RG = ‘AzureRG’
$subnetName = ‘default’
$nicName = ‘sw-sed-azure-01011’
$location = ‘East US
$ipAddress = ’10.10.0.10’

Create an object for the VM using Get-AzureRmVM:
$VM = Get-AzureRmVM -Name $vmName -ResourceGroupName $RG

Now, create an object for the virtual network using Get-AzureRmVirtualNetwork:
$vnet = Get-AzureRmVirtualNetwork -Name $vnetName -ResourceGroupName $RG

The new NIC needs to be connected to a subnet ($subnetName), but first, the subnet ID must be received before starting to work with it in PowerShell: $subnetID = (Get-AzureRmVirtualNetworkSubnetConfig -Name $subnetName -VirtualNetwork $vnet).Id

Finally, a new NIC can be created using the New-AzureRmNetworkInterface cmdlet: New-AzureRmNetworkInterface -Name $nicName -ResourceGroupName $RG -Location $location -SubnetId $subnetID -PrivateIpAddress $ipAddress A new NIC has been created and can now be attached to the VM. First, create an object for the NIC using the Get-AzureRmNetworkInterface cmdlet: $NIC = Get-AzureRmNetworkInterface -Name $nicName -ResourceGroupName $RG

Add the NIC to the VM configuration:
$VM = Add-AzureRmVMNetworkInterface -VM $VM -Id $NIC.Id

To check that the configuration has been changed to include the new NIC, run the command below to see the list of NICs attached to the VM:
$VM.NetworkProfile.NetworkInterfaces

Assign the first NIC as the primary:
$VM.NetworkProfile.NetworkInterfaces.Item(0).Primary = $true

Lastly, commit the new configuration using the Update-AzureRmVM cmdlet:
Update-AzureRmVM -VM $VM -ResourceGroupName $RG
