 **Without Accelerated Networking**, all networking traffic in and out of the VM traverses the host and the virtual switch. The virtual switch provides all policy enforcement to network traffic. Policies include network security groups, access control lists, isolation, and other network virtualized services. To learn more about virtual switches, see [Hyper-V Virtual Switch](/windows-server/virtualization/hyper-v-virtual-switch/hyper-v-virtual-switch).

 If you use a custom image that supports Accelerated Networking, make sure you have the required drivers to work with Mellanox ConnectX-3, ConnectX-4 Lx, and ConnectX-5 NICs on Azure. Accelerated Networking also requires network configurations that exempt configuration of the virtual functions on the mlx4_en and mlx5_core drivers. Images with cloud-init version 19.4 or greater have networking correctly configured to support Accelerated Networking during provisioning.
