Chapter 1 Installing the Cisco Nexus 1000V for Microsoft Hyper-V
Prerequisites for Installing the VSM Software
Guidelines and Limitations
It is your responsibility to monitor and install all the relevant patches from Microsoft on the Windows
hosts.
System Requirements
This section describes the hardware and software requirements.
• Hardware Requirements, page 1-2
• Software Requirements, page 1-2
Hardware Requirements
The hardware must meet the requirements set by Microsoft to run the Hyper-V role. The Cisco Nexus
1000V for Microsoft Hyper-V Virtual Supervisor Module (VSM) requires VMs with the following
configuration:
• 4 GB minimum of hard disk space
• 4 GB minimum of RAM
• As a best practice, we recommend that you have four network adapters (network interface
cards—NICs) on the host where Microsoft Hyper-V is installed. You can have various combinations
depending on the hardware that you have. For example, you can have one NIC with four ports or
four NICs with one port each.
Software Requirements
To install and bring up a Cisco Nexus 1000V for Microsoft Hyper-V, you need the following server
setup:
• Microsoft System Center Virtual Machine Manager (SCVMM) 2012 SP1 UR3 (build version
3.1.6027.0) or Microsoft System Center Virtual Machine Manager (SCVMM) WS2012-R2 (build
version 3.2.7510)
• Windows 2012 hosts
• Windows 2012 R2 hosts
• Active Directory server
To configure the VSM, you need the following information:
• VSM IP address
• VSM domain ID (1—1023)—This ID is used for high availability (HA)
• Layer 3 connectivity between a VSM and the hosts that run a VEM is required.
– Layer2 mode is not supported.
– Layer3 UDP port number 4785
– Communication between the VSM and VEM occurs over UDP port number 4785 that uses the
Cisco Nexus Control Protocol (CNCP)
• TCP Port 80 is open on the network for communication from the SCVMM to VSM. In case of https,
the TCP Port is 443.

Chapter 1 Installing the Cisco Nexus 1000V for Microsoft Hyper-V
VSM NIC Ordering
VSM NIC Ordering
The VSM creates interfaces in an ascending MAC address order of the virtual NIC offered by Microsoft
Hyper-V. Currently, Microsoft Hyper V provides no guarantees that this order is the same as displayed
at the VSM VM Settings panel. The VSM always uses its first interface as control0 and its second
interface as mgmt0. The network profiles for these two interfaces might need different VLANs.
Therefore, you should verify that the interfaces are selected by the VSM in the same order that are
displayed in the Settings panel.
Execute the following CLI on the VSM to verify the order of the management and control mac addresses.
Nexus1000V# show interface mac-address
--------------------------------------------------------------------------------
Interface Mac-Address Burn-in Mac-Address
--------------------------------------------------------------------------------
mgmt0 001d.d8b7.1e61 001d.d8b7.1e61
control0 001d.d8b7.1e60 001d.d8b7.1e60
If the order is not the same, you can use the following commands to specify the preferred MAC to
control0/mgmt0 interface mappings:
• system internal control-mac XXXX.XXXX.XXXX
• system internal mgmt-mac XXXX.XXXX.XXXX
These commands require that you entere the copy running-config startup-config command afterwards
to make the change persistent and effective after the next VSM reload.
switch# show system internal interface mac-address
Sample output:
Interface Preferred MAC
sh interface mac-address
--------- --------------
mgmt0 cccc.bbbb.aaaa
control0 aaaa.bbbb.cccc
If any of the preferred MAC for control0/mgmt0 selected by users is not available at VSM boot up, the
driver ignores it and it picks another interface instead (following MAC ascending order). In that case,
the system logs an error with a syslog as follows:
%KERN-3-SYSTEM_MSG: Preferred MAC (aaaa.bbbb.cccc) for control0 not found – kernel

Chapter 1 Installing the Cisco Nexus 1000V for Microsoft Hyper-V
Installing the VSM Software
Installing SCVMM Components
To install the SCVMM components, perform the following steps:
Step 1 Install the Cisco Provider MSI.
a. Install the Nexus1000V-VSEMProvider-5.2.1.SM1.5.2.0.msi from the Cisco Nexus1000V zip
location on the SCVMM server in order to establish communication between SCVMM and the
Cisco Nexus1000V VSM.
Note The MSI installation restarts the SCVMM service.
b. Verify that the Cisco Provider is installed properly as follows:
• Open the SCVMM console.
• Navigate to the Settings Pane.
• Click on Configuration Providers.
c. Verify the Cisco Systems Nexus 1000V extension is displayed.
Step 2 Install Cisco VSM template files as follows:
After downloading the Cisco Nexus 1000V for Microsoft Hyper-V package, complete the following
steps to install the VSM template:
• On the SCVMM server, open the PowerShell console from the SCVMM console.
• Run the script Register-Nexus1000VVSMTemplate.ps1 from the following location
C:\Program Files\Cisco\Nexus1000V\Nexus1000V-VSMTemplate.
This script imports the Cisco VSM Template in the SCVMM Library
• To verify the template, do the following:
– Navigate to the Templates tab.
– Choose Templates. On the right pane, the Nexus 1000V-VSM-Template is listed.
Step 3 Copy the VEM to the SCVMM repository.
The VEM is an MSI file that needs to be placed in the following location on SCVMM server:
ALLUSERSPROFILE%\Switch Extension Drivers. For example, C:\ProgramData\Switch Extension
Drivers. SCVMM uses the MSI file during Add host operation.
Caution Do not install the VEM on the SCVMM server. Only copy the file to the location specified.
Step 4 Copy the VSM ISO file. For example, copy N1000vh-dk9.5.2.1.SM1.5.0.339 to the SCVMM library in
the following location on SCVMM server: \\VMName\MSSCVMMLibrary. After copying the ISO file,
make sure to refresh the SCVMM library so that SCVMM detects the copied ISO.
