 Use [Get-AzNetworkInterface](/powershell/module/az.network/get-aznetworkinterface) to retrieve the network interface of the virtual machine, and then use [Get-AzApplicationSecurityGroup](/powershell/module/az.network/get-azapplicationsecuritygroup) to retrieve the application security group. Finally, use [Set-AzNetworkInterface](/powershell/module/az.network/set-aznetworkinterface) to associate the application security group with the network interface. The following example associates the _asg-web_ application security group with the _vm-web-nic_ network interface:
 
 ```azurepowershell-interactive
-$params = @{
+$params1 = @{
     Name = "vm-web-nic"
     ResourceGroupName = "test-rg"
 }
-$nic = Get-AzNetworkInterface @params

-$params = @{

     Name = "asg-web"
     ResourceGroupName = "test-rg"
 }
-$asg = Get-AzApplicationSecurityGroup @params
+$asg = Get-AzApplicationSecurityGroup @params2
 
 $nic.IpConfigurations[0].ApplicationSecurityGroups = @($asg)
 
-$params = @{
+$params3 = @{
     NetworkInterface = $nic
 }
-Set-AzNetworkInterface @params
+Set-AzNetworkInterface @params3
 ```
 
 Repeat the command to associate the _asg-mgmt_ application security group with the _vm-mgmt-nic_ network interface.
 
 ```azurepowershell-interactive
-$params = @{
+$params1 = @{
     Name = "vm-mgmt-nic"
     ResourceGroupName = "test-rg"

 Enter the user name and password you specified when creating the VM (you may need to select **More choices**, then **Use a different account**, to specify the credentials you entered when you created the VM), then select **OK**. You may receive a certificate warning during the sign-in process. Select **Yes** to proceed with the connection.
 
 The connection succeeds, because port 3389 is allowed inbound from the internet to the _asg-mgmt_ application security group that the network interface attached to the _vm-mgmt_ VM is in.
