Introduction

The Cisco Nexus 1000V provides a distributed, Layer 2 virtual switch that extends across many virtualized hosts. The Cisco Nexus 1000V manages a data center. Each server in the data center is represented as a line card in the Cisco Nexus 1000V and can be managed as if it were a line card in a physical Cisco switch.

When server virtualization is implemented, the edge of the network is pushed from the traditional network access layer, which is implemented in physical switches, to the virtual network access layer that is implemented through the software in the Server Hypervisor. The Cisco Nexus 1000V is an intelligent virtual network access layer switch that runs Cisco NX-OS, which is Cisco’s data center operating system common to all of Cisco’s data center products.

Operating inside the Microsoft Hyper-V Hypervisor, the Cisco Nexus 1000V supports the Cisco Virtual Network-Link (VN-Link) server virtualization technology to provide the following:

• Policy-based Virtual Machine (VM) connectivity
• Mobile VM security and network policy
• Nondisruptive operational model for your server virtualization and networking teams

Data center virtualization servers and VMs are not managed the same way as physical servers. Server virtualization is treated as a special deployment, leading to longer deployment time, with a greater degree of coordination among server, network, storage, and security administrators. With the Cisco Nexus 1000V, you have a consistent networking feature set and a configuration and provisioning model for both the physical and the virtual networks.

VM networks can use the same network configuration, security policy, diagnostic tools, and operational models as physical server deployments that are connected to physical switches. This unified approach to quicker deployment and troubleshooting makes virtualization environments no different from nonvirtualized deployments.

Developed with Microsoft, the Cisco Nexus 1000V is Microsoft certified and integrates with the Windows Server and Systems Center Virtual Machine Manager (SCVMM).

The Cisco Nexus 1000V consists of two basic components:

• Virtual Supervisor Module (VSM), also known as the Control Plane (CP). The VSM acts as the supervisor and contains the Cisco command-line interface (CLI), configuration, and high-level features.
• Virtual Ethernet Module (VEM), also known as the Data Plane (DP). The VEM acts as a line card and runs in each Hyper-V virtual switch to handle packet forwarding and other localized functions.

Hyper-V Webinar

Cisco offers a Cisco Nexus 1000V for Microsoft Hyper-V webinar as either a video demonstration or a PDF download. In the webinar, you can learn how the Cisco Nexus 1000V virtual access/distributed switch can simplify your Hyper-V virtual environment through a nondisruptive operational model, policy based provisioning, and a strong services ecosystem. You can also learn about the Cisco Nexus 1000V architecture, how it integrates with Microsoft SCVMM, and the networking capabilities it brings to Hyper-V environments.

Administrative Model

The Cisco Nexus 1000V for Microsoft Hyper-V consists of two distinct administrative entities that manage the environment on the same set of hardware. Each entity has its own separate goals, abilities, and responsibilities.

Server and VM policies can be set only by the server administrator through SCVMM or its management tools. Network policies can be set only by the network administrator through the VSM or its management tools.

Network and server administrators cannot make administrative changes to the system at the same time. Operations such as deployment, upgrade, configuration, and troubleshooting, can be carried out in an asynchronous fashion by administrators.

If the network administrator has set up appropriate policies, the server administrator can add, remove, and move both physical hosts and VMs, as well as install physical interfaces in hosts and add virtual interfaces to VMs.

Software Compatibility

Step 5 Copy the Nexus 1000V VEM MSI (Nexus1000V-VEM-5.2.1.SM1.5.2a.0.msi) to the host.

Step 6 Double click the MSI file to install the MSI.

Step 7 Bring the host out of maintenance mode.

Step 8 Refresh the Switch Extension Manger for Cisco Nexus1000V on SCVMM.

Step 9 From the SCVMM console, navigate to Fabric > Logical Switch and select Hosts.
