Enable Accelerated Networking For Virtual Machines
More Info:
Ensure that Accelerated Networking feature is enabled for your Azure virtual machines (VMs) in order to provide low latency and high throughput for the network interfaces (NICs) attached to the VMs. Accelerated networking enables single root input/output virtualization (SR-IOV) for virtual machines, vastly improving its networking performance. This high-performance pathway bypasses the host from the datapath, reducing latency, jitter and CPU utilization, so it can be used with the most demanding network workloads that can be installed on the supported VM types.Risk Level

Using Console
Using Console
To remediate the misconfiguration “Enable Accelerated Networking for Virtual Machines” in Azure using the Azure console, follow these steps:
- Log in to the Azure portal.
- Navigate to the Virtual Machine that needs to be configured.
- Click on the “Networking” option in the left-hand menu.
- Click on the “Enable” button next to “Accelerated Networking.”
- Choose the appropriate network interface and click “Save.”
Using CLI
Using CLI
To enable Accelerated Networking for Virtual Machines in Azure using Azure CLI, follow the below steps:
- Open the Azure CLI in your terminal or Azure Cloud Shell.
-
Run the following command to check if Accelerated Networking is already enabled for the VM:
-
Once you have verified that Accelerated Networking is not enabled, run the following command to enable it:
- Wait for a few minutes for the changes to take effect.
-
Run the following command to verify that Accelerated Networking is enabled for the VM:
If the output is “true”, then Accelerated Networking has been successfully enabled for the VM.
Using Python
Using Python
To remediate the misconfiguration of enabling Accelerated Networking for Virtual Machines in Azure using Python, you can use the Azure Python SDK. Here are the steps to follow:
- Install the Azure Python SDK by running the following command in your terminal:
- Authenticate with Azure by creating a Service Principal and assigning it the Contributor role for the subscription. You can do this using the Azure CLI or the Azure Portal.
- Import the necessary modules in your Python script:
- Set the credentials for the Service Principal:
- Create a ComputeManagementClient object using the credentials:
- Get a list of all the virtual machines in the subscription:
- For each virtual machine, check if Accelerated Networking is already enabled. If not, enable it:
- Save and run the Python script. This will enable Accelerated Networking for all the virtual machines in the subscription that do not have it enabled.
