Hyper-V 3.0 on Windows Server 2012 offers a new feature called an extensible virtual switch. This feature allows you to replace the Windows integrated virtual switch in Hyper-V with a third-party switch, such as the Cisco 1000V. You can get a quick overview of Hyper-V extensible virtual switches here.
The Cisco 1000V virtual switch provides many advanced capabilities to Hyper-V VMs such as advanced switching (private VLANs, ACLs, PortSecurity, and Cisco vPath), security, monitoring, and manageability. Best of all it’s free to download here!
The following information comes from Cisco’s Cisco Nexus 1000V Switch for Microsoft Hyper-V website:
