In the DHCP console, choose a scope that will be used to issue leases to both physical and virtual DHCP clients. #Dhcp enable microsoft hosted virtual adapter macTo configure a MAC address based DHCP policy For more information, see MAC addressing in Hyper-V. By default, the Hyper-V server will use a MAC address range that includes values of 00 to FF for the sixth octet, with the same first five octets. You must replace the values used in this example with the MAC address range used in your environment. In this procedure, the example MAC address range used is 00-15-5D-9F-DF-00 to 00-15-5D-9F-DF-FF. Use the following procedure to configure a policy for virtual machines based on MAC addresses. Configure a MAC address based DHCP policy #Dhcp enable microsoft hosted virtual adapter how toThe following procedure demonstrates how to configure this policy. If you would like the policy to cater to all virtual machines regardless of the host or host group, use the MAC address prefix 00-15-5D with a wildcard (00155D*). To group virtual machines in a DHCP policy, create a policy with conditions based on MAC address or MAC address prefix.įor example, if MAC addresses are assigned from the range 00-15-5D-9F-DF-00 to 00-15-5D-9F-DF-FF, you can create a policy based on the MAC address prefix 00-15-5D-9F-DF. This kind of support is provided by all the virtualization platforms. The range can be modified, if desired, by editing the MaximumMacAddress and MinimumMacAddress registry keys located under HKLM\Software\Microsoft\Windows\NT\CurrentVersion\Virtualization. The starting and ending addresses are derived from the lowest two octets in an IPv4 address on the Hyper-V server, and will begin with Microsoft’s Organizationally Unique Identifier (OUI) of 00-15-5D. To use a static MAC address, select Static and then specify a MAC address.įor dynamic MAC addressing in Hyper-V, a range of 256 possible MAC addresses is used by default. In this example, the Hyper-V server is using a dynamic MAC address range of 00-15-5D-9F-DF-00 to 00-15-5D-9F-DF-FF. To view MAC address settings in Hyper-V, right-click a virtual machine, click Settings, and then under Network Adapter, click Advanced Features. The default option is to use a dynamic MAC address, which means that Hyper-V will generate a MAC address for the network adapter. With Hyper-V, you can configure a virtual machine to use a dynamic or a static MAC address. DHCP clients that match the policy are assigned IP addresses from a specific IP address range, a short lease duration, and different DHCP options such as default gateway and DNS server. These configuration parameters can be managed by creating a DHCP policy based on MAC address prefix. Due to their dynamic nature, virtual machines might require:Ī different, often shorter, lease durationĪ different default gateway for use in traffic management However, this capability can bring with it some unique requirements. Virtual machinesĪn advantage of virtual machines is that they can be added and removed dynamically from the network depending upon load requirements. DHCP policies can help to simplify management of hybrid environments by enabling greater flexibility and control of the network configuration of DHCP clients. Larger, flat networks are typically more efficient and less complex to manage than a design that includes multiple smaller, partitioned networks. Placing virtual and physical devices on separate subnets enables customization of network settings but adds complexity. Management resources: Physical servers and devices that provide automation, access control, monitoring, and scalability for virtual networks, such as System Center Virtual Machine Manager are a critical component.Īs a consequence, organizations often need to manage a hybrid environment consisting of both physical and virtual resources. Network resources: Physical devices such as routers and switches that connect virtual networks to other networks are necessary. #Dhcp enable microsoft hosted virtual adapter windowsStorage resources: Clustered file servers such as the Scale-Out File Server in Windows Server 2012 are a critical component of any virtualization solution. However, virtual networks also require physical resources, including:Ĭompute resources: Physical servers that host virtual machines, such as a Hyper-V cluster are required. More and more organizations are leveraging the advantages of virtualization in today’s business environment. See the following sections in this topic:Ĭonfigure a MAC address based DHCP policy
