Configuring the Cisco Nexus 1000V Switch for Microsoft Hyper-V

This chapter contains the following sections:

About Microsoft System Center Virtual Machine Manager

Microsoft System Center Virtual Machine Manager (SCVMM) 2012 SP1 is a comprehensive IT infrastructure, virtualization, and cloud management platform. With this platform, you can manage your applications and services across multiple hypervisors and across public, hosted, and private cloud infrastructures to deliver flexible and cost-effective IT services. Microsoft SCVMM allows you, as the administrator, to configure and manage the servers, the network, and the storage resources.

Microsoft SCVMM 2012 SP1 introduces the following constructs to model and configure the networks on the Hyper-V servers:

  • Logical network

  • Network site

  • VM network

  • VM subnet

  • IP pool

  • Uplink profile

  • Port classification

  • Logical switch

About the Cisco Nexus 1000V Switch for the Microsoft Hyper-V Configuration

Microsoft SCVMM SP1 models the physical networks as a fabric. The Cisco Nexus 1000V has introduced a capability to configure and edit the following new objects based on Microsoft SCVMM SP1 network object model:

  • Logical networks

  • Network segment pools (results in the creation of network sites on virtual machine manager [VMM])

  • Network segments (results in the creation of a virtual machine [VM] network and VM subnet)

  • IP pools

  • Network uplink

Logical Networks and Network Segment Pools

A logical network (for example, Internet or intranet) is a connectivity abstraction that models separate networks managed by an enterprise. A logical network is composed of one or more network segment pools, and each network segment pool is a group of VLANs, IP subnets, or VLAN/IP subnet pairs. The logical network hides the VLANs and IP subnets that make the network from all the users (the VM network administrators, the tenant administrators, and the server administrators) other than the fabric administrator managing the physical fabric.

Network Segments

A network segment is associated with a unique broadcast domain. A network segment facilitates the availability of the network resources to a virtual machine. Microsoft SCVMM uses the VM networks and the VM subnets to provide the isolated virtual machine networks. When the Cisco Nexus 1000V switch is used to manage the virtual network, the VMM administrator creates the VM networks that use external isolation.

As a network administrator, you can create network segment on the Cisco Nexus 1000V switch to provide external isolation. You can provide the isolated networks using the VLANs and the private VLANs.

Note

In the Cisco Nexus 1000V for Microsoft Hyper-V, a VLAN is not created to define a bridge domain. Instead, a network segment is created on a Virtual Supervisor Module (VSM). The VSM provides the switch control and management plane for the Cisco Nexus 1000V switch. Creating a network segment triggers VLANs to be created automatically.

IP Pools

You can assign a range of IP addresses to the hosts and to the virtual machines that are running inside the Microsoft SCVMM-managed environment using an IP pool template. The IP pool template is the address template that is applied to the network segments. When you create an IP pool template for a VM network, you can define a range of IP addresses that are used by the VMs managed by Microsoft SCVMM.

Network Uplink

The uplink network is a combination of an Ethernet port profile and one or more network segment pools. When applied to the physical adapter on a server, the uplink network defines the policy and the VLANs that are allowed on the physical adapter. Each uplink network configured on the VSM is available as an uplink port profile to the Microsoft SCVMM administrator.
