You can use the local Azure CLI.

• If you prefer, install the Azure CLI to run CLI reference commands.

• Local Azure CLI, see how to install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.

The following procedure creates a virtual network with a resource subnet.

1. In the portal, search for and select Virtual networks.

2. On the Virtual networks page, select + Create.

3. On the Basics tab of Create virtual network, enter or select the following information:

   Expand table

   Setting	Value
   Project details
   Subscription	Select your subscription.
   Resource group	Select Create new. Enter test-rg in Name. Select OK.
   Instance details
   Name	Enter vnet-1.
   Region	Select (Asia Pacific) China East 2.

   

4. Select Next: IP Addresses to proceed to the IP Addresses tab.

5. In the address space box in Subnets, select the default subnet.

6. In Edit subnet, enter or select the following information:

   Expand table

   Setting	Value
   Subnet name	Enter subnet-1.
   Subnet address range	Enter 10.0.0.0/24.

   

7. Select Save.

8. Select Review + create at the bottom of the screen, and when validation passes, select Create.

Create a resource group with New-AzResourceGroup named test-rg in the chinanorth3 location.

$rg =@{
    Name = 'test-rg'
    Location = 'chinanorth3'
}
New-AzResourceGroup @rg

Use New-AzVirtualNetwork and New-AzVirtualNetworkSubnetConfig to create a virtual network.

## Create backend subnet config ##
$subnet = @{
    Name = 'subnet-1'
    AddressPrefix = '10.0.0.0/24'
}
$subnetConfig = New-AzVirtualNetworkSubnetConfig @subnet 

## Create the virtual network ##
$net = @{
    Name = 'vnet-1'
    ResourceGroupName = 'test-rg'
    Location = 'chinanorth3'
    AddressPrefix = '10.0.0.0/16'
    Subnet = $subnetConfig
    EnableEncryption = 'true'
    EncryptionEnforcementPolicy = 'AllowUnencrypted'
}
New-AzVirtualNetwork @net

Create a resource group with az group create named test-rg in the chinanorth3 location.

  az group create \
    --name test-rg \
    --location chinanorth3

Use az network vnet create to create a virtual network.

  az network vnet create \
    --resource-group test-rg \
    --location chinanorth3 \
    --name vnet-1 \
    --enable-encryption true \
    --encryption-enforcement-policy allowUnencrypted \
    --address-prefixes 10.0.0.0/16 \
    --subnet-name subnet-1 \
    --subnet-prefixes 10.0.0.0/24 

Use the following steps to enable encryption for a virtual network.

1. In the search box at the top of the portal, begin to enter Virtual networks. When Virtual networks appears in the search results, select it.

2. Select vnet-1 to open the vnet-1 pane.

3. On the service menu, select Overview, and then select the Properties tab.

4. Under Encryption, select Disabled.

   

5. Select the box next to Virtual network encryption.

6. Select Save.

You can also enable encryption on an existing virtual network by using Set-AzVirtualNetwork. This step isn't necessary if you created the virtual network with encryption enabled in the previous steps.

## Place the virtual network configuration into a variable. ##
$net = @{
    Name = 'vnet-1'
    ResourceGroupName = 'test-rg'
}
$vnet = Get-AzVirtualNetwork @net

## Enable encryption on the virtual network ##
$vnet.Encryption = @{
    Enabled = 'true'
    Enforcement = 'allowUnencrypted'
}
$vnet | Set-AzVirtualNetwork

You can also enable encryption on an existing virtual network by using az network vnet update. This step isn't necessary if you created the virtual network with encryption enabled in the previous steps.

  az network vnet update \
    --resource-group test-rg \
    --name vnet-1 \
    --enable-encryption true \
    --encryption-enforcement-policy allowUnencrypted

1. In the search box at the top of the portal, begin to enter Virtual networks. When Virtual networks appears in the search results, select it.

2. Select vnet-1 to open the vnet-1 pane.

3. On the service menu, select Overview, and then select the Properties tab.

4. Verify that Encryption is set to Enabled.

   

Use Get-AzVirtualNetwork to view the encryption parameter for the virtual network you created previously.

## Place the virtual network configuration into a variable. ##
$net = @{
    Name = 'vnet-1'
    ResourceGroupName = 'test-rg'
}
$vnet = Get-AzVirtualNetwork @net

To view the parameter for encryption, enter the following information:

$vnet.Encryption

Enabled Enforcement
------- -----------
True   allowUnencrypted

Use az network vnet show to view the encryption parameter for the virtual network you created previously.

  az network vnet show \
    --resource-group test-rg \
    --name vnet-1 \
    --query encryption \
    --output tsv

user@Azure:~$ az network vnet show \
    --resource-group test-rg \
    --name vnet-1 \
    --query encryption \
    --output tsv
True   AllowUnencrypted

When you finish using the resources that you created, you can delete the resource group and all its resources:

1. In the Azure portal, search for and select Resource groups.

2. On the Resource groups page, select the test-rg resource group.

3. On the test-rg page, select Delete resource group.

4. Enter test-rg in Enter resource group name to confirm deletion, and then select Delete.

When you no longer need this resource group, use Remove-AzResourceGroup to remove the resource group and all the resources it contains.

$cleanup = @{
  Name  = "test-rg"
}
Remove-AzResourceGroup @cleanup -Force

When you finish with the virtual network, use az group delete to remove the resource group and all its resources.

az group delete \
    --name test-rg \
    --yes
