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 with Microsoft Servers
Ensure that the servers that run the Cisco Nexus 1000 VSM and VEM are in the Hardware Compatibility list.
This release of the Cisco Nexus 1000V supports the following server:
For additional compatibility information, see the Cisco Nexus 1000V and Microsoft Hyper-V Compatibility Information, Release 5.2(1)SM3(1.1)
Software Compatibility with the Cisco Nexus 1000V
This release supports upgrades from Release 5.2(1)SM1(5.1) and later. For information about the upgrade procedure, see the Cisco Nexus 1000V for Microsoft Hyper-V Installation and Upgrade Guide, Release 5.2(1)SM3(1.1).
Note If you are upgrading from Release 5.2(1)SM1(5.1) to Release 5.2(1)SM3(1.1), and you have the permanent or evaluation license installed, see the Cisco Nexus 1000V for Hyper-V License Configuration Guide, Release 5.2(1)SM1(5.2).
New Software Features
The following software features were added in Cisco Nexus 1000V for Hyper-V Release 5.2(1)SM3(1.1):
VXLAN 1.0
A VXLAN uses an IP multicast network to send broadcast, multicast, and unknown unicast flood frames. Each multicast mode VXLAN has an assigned multicast group ID address. When a new VM joins a host in multicast mode VXLAN, VEM joins the assigned multicast group ID address by sending IGMP join messages. Flood traffic—broadcast, multicast, and unknown unicast—from the VM is encapsulated and is sent using the assigned multicast group IP as the destination IP address. Packets sent to known unicast MAC addresses are encapsulated and sent directly to the destination server VTEP IP addresses.
Hyper-V Network Virtualization
Hyper-V Network Virtualization (HNV) provides a virtual network similar to how server virtualization (hypervisor) provides virtual machines to the operating system. Network virtualization decouples virtual networks from the physical network infrastructure and removes the constraints of VLAN and hierarchical IP address assignment from virtual machine provisioning. This flexibility makes it easy to move to IaaS clouds and efficient for hosts and data center administrators to manage their infrastructure, while maintaining the necessary multitenant isolation, security requirements, and supporting overlapping virtual machine IP addresses.
Limitations and Restrictions
This section describes the limitations and restrictions of the Cisco Nexus 1000V for Hyper-V, Release 5.2(1)SM3(1.1).

Step 2 At the Log In screen, enter your registered Cisco.com username and password; then, click Log In. The Bug Search page opens.
Note If you do not have a Cisco.com username and password, you can register for them at http://tools.cisco.com/RPF/register/register.do.
Step 3 To search for a specific bug, enter the bug ID in the Search For field and press Return.
Step 4 To search for bugs in the current release:
a. In the Search For field, enter Cisco Nexus 1000V and press Return. (Leave the other fields empty.)
b. When the search results are displayed, use the filter tools to find the types of bugs you are looking for. You can search for bugs by modified date, status, severity, and so forth.
Tip To export the results to a spreadsheet, click the Export Results to Excel link.
MIB Support
The Cisco Management Information Base (MIB) list includes Cisco proprietary MIBs and many other Internet Engineering Task Force (IETF) standard MIBs. These standard MIBs are defined in Requests for Comments (RFCs). To find specific MIB information, you must examine the Cisco proprietary MIB structure and related IETF-standard MIBs supported by the Cisco Nexus 1000V.
The MIB Support List is available at the following FTP site:
