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:
Chapter 1 Installing the Cisco Nexus 1000V for Microsoft Hyper-V
• 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
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
VSM NIC Ordering
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

Preparing the Microsoft Hyper-V Hosts (Optional)
Before you add the hosts to the logical switch, you can prepare the Microsoft Hyper-V hosts. This step
is optional.
This section includes the following topics:
• Configuring the MTU with the Cisco Nexus 1000V, page 1-22
• VMQ Processor Configuration with the Cisco Nexus 1000V, page 1-23
• Changing the RSS Registry, page 1-23
Configuring the MTU with the Cisco Nexus 1000V
In Microsoft Hyper-V, the VSM does not manage the Maximum Transmission Unit (MTU) setting of
VM NIC or physical adapters. All physical adapters added to the Cisco Nexus 1000V switch should have
the same MTU configured and the PNIC MTU should not be changed after it is added to the switch.
To configure the MTU, perform the following steps:
Cisco Nexus 1000V for Microsoft Hyper-V Installation Guide, Release 5.2(1)SM1(5.2)
1-22
OL-30997-01
Page 23
Chapter 1 Installing the Cisco Nexus 1000V for Microsoft Hyper-V
Step 1 Open View Network Connections from the Server Manager or Control Panel or by typing ncpa.cpl from
a command line.
Step 2 Right click the adapter and choose Properties.
Step 3 Click Configure under the adapter properties window.
Step 4 Click the Advanced tab.
Step 5 Under Property, click on Jumbo Packet.
Step 6 Set the desired value of the Jumbo Packet property.
Repeat this procedure for all the adapters that are added to Cisco Nexus 1000V logical switch.
Note Certain adapters allow the MTU change only through their own adapter manager. For example,
the MTU of the Cisco VIC cards can be changed thorugh the UCSM or ILO.
VMQ Processor Configuration with the Cisco Nexus 1000V
Installing the VSM Software
VMQ allows the network traffic received on an adapter to be spread over multiple CPU cores which
provides better performance. The following two factors are important in determining if the VMQ
operates correctly:
• The receive side scaling (RSS) CPU number determines the lowest CPU core that can be used by
RSS.
• The maximum number of RSS CPU determines how many CPU cores can be used by RSS.
The above two factors can be configured so that the same CPU core is not used by multiple NICs.
Note Changing the RSS registry is a disruptive operation and causes the Ethernet adapter to flap.
The Cisco Nexus 1000V supports the following port-channel operational modes: Link Aggregation
Control Protocol (LACP) and vPC.
The LACP utilizes the same Subgroup id for all the members of a port-channel. The RSS Base CPU and
Max RSS Processors should be configured with same value for all member ports.
MAC pinning / manual pinning port-channel use multiple subgroup ids within the members of the
port-channel. Therefore, the RSS Base CPU and Max RSS processors should be configured so that the
same CPU core is not used by multiple NICs.
Changing the RSS Registry
To change the RSS registry, perform the following steps:
Step 1 Open View Network Connections from the Server Manager or Control Panel or by typing ncpa.cpl from
a command line.
Step 2 Right-click the adapter and choose properties.
Step 3 Under the Adapter Properties window, click Configure.

Page 24
Installing the VSM Software
Step 4 Click the Advanced tab.
Step 5 Click Maximum Number of RSS Processor and enter a value.
Step 6 Click Starting RSS CPU and enter a value.
Repeat this procedure for all the adapters that you want VMQ to be enabled on.
The RSS setting cannot be modified through the network connections for certain adapters. For those
adapters, you must set the registry keys directly using the registry editor. Check the Microsoft
documentation for information about changing the registry.
Adding Hosts to a Logical Switch
After a logical switch is created, you can update the properties of the logical switch.
Step 1 In the left navigation pane, choose the server, under Fabric > Servers > All Hosts, right-click, and
choose Properties. The Properties window opens.
Step 2 In the left navigation pane of the Properties window, click Virtual Switches.
Step 3 In the Virtual Switches pane, in the New Virtual Switches field, click New Logical Switch. Choose
the correct logical switch and physical adapters to assign to the logical switch. The module is added to
Cisco Nexus1000V VSM.
Chapter 1 Installing the Cisco Nexus 1000V for Microsoft Hyper-V
Note The MGMT PNIC can be added to the logical switch only when the switch is created. Adding it
later results in a loss of host connectivity.
Step 4 Under the Physical Adapter header, choose a network adapter from the drop-down list in the Adapter
field. In the Uplink Port Profile field, confirm the uplink port profile for the adapter.
Step 5 For port-channeling, click Add to add a second network adapter. Choose a different network adapter,
confirm the uplink port profile, and click OK.
Note Do not use the same port profile for both adapters. If you have configured the port channels, then you
can use the same port-profile on both the adapters. Refer the NSM Configuration Guide for more details.
Now, the Cisco Nexus 1000V package that was copied on the SCVMM is installed on the host.
Note We recommend that one logical switch is created per VSM.
Connecting the VM Network Adapter to the Logical Switch
To connect the VM network adapter to the Logical Switch, perform the following steps:
Step 1 Choose the VM network adapter.
