Figure 1 Cisco Nexus 1000V Installation Diagram

Prerequisites

This section includes the following prerequisites for installing the Cisco Nexus 1000V:

•VSM Prerequisites

•Host Prerequisites

•Upstream Switch Prerequisites

VSM Prerequisites

The following prerequisites apply to the VSM:

•We recommend that you install redundant VSMs. For information about high availability and redundancy, see the Cisco Nexus 1000V High Availability and Redundancy Configuration Guide, Release 4.2(1)SV1(4).

•If you are installing redundant VSMs, make sure that you first install and set up the software on the primary VSM before installing and setting up the software on the secondary VSM.

•To improve redundancy, install primary and secondary VSM virtual machines in separate hosts connected to different upstream switches. For other recommendations about your Cisco Nexus 1000V implementation, see the Cisco Nexus 1000V Getting Started Guide, Release 4.2(1)SV1(4a).

•You have already identified the HA role for this VSM from those listed below.

HA Role	Single Supervisor System	Dual Supervisor System
Standalone	X
Primary		X1
Secondary		X2

1 Install the first VSM of a dual supervisor pair as the primary VSM. 2 Install the second VSM of a dual supervisor pair as the secondary VSM.

•The VSM VM may run on ESX 3.5 or later.

•The Cisco Nexus 1000V software includes evaluation licenses for 16 CPU sockets for a period of 60 days. These licenses are used only if there are no permanent licenses installed on the VSM. The evaluation period of 60 days starts when you install the software. For more information about licenses, see the Cisco Nexus 1000V License Configuration Guide, Release 4.2(1)SV1(4a).

•You are familiar with the Cisco Nexus 1000V example installation that is shown in Figure 1.

Host Prerequisites

The following prerequisites apply to the ESX or ESXi hosts to be used for the Cisco Nexus 1000V:

•You have already installed and prepared the vCenter Server for host management using the instructions from VMware.

•You have the VMware documentation for installing software on the vSphere Client.

•You have already installed the VMware Enterprise Plus license on the hosts.

•There is at least one host for the Cisco Nexus 1000V. If you plan to use VMotion, you need two hosts.

•All VEM hosts must be running ESX or ESXi software version 4.0 Update 1 or later.

•A host requires a minimum of 2 GB of physical RAM. If it also hosts a Cisco Nexus 1000V VSM VM, it needs a minimum of 4 GB of physical RAM. If it also hosts the vCenter Server VM, additional memory may be needed.

•Each host has a minimum of the following physical NICs:

–One physical NIC for a Service Console or Management.

–One physical NIC for the traffic between VSM and VEM and for VM data traffic.

•All hosts must have Layer 2 connectivity to each other.

•If you are using a set of switches, make sure that the inter-switch trunk links carry all relevant VLANs, including control and packet VLANs. The uplink should be a trunk port carrying all VLANs configured on the host.

•The VSM can reside on a server running a virtual Ethernet module (VEM), or a VMware vSwitch or DVS. If the host is running a VEM, that VEM can be managed by the VSM on the same host or a VSM on another host.

•For instructions on installing the optional VMware Update Manager (VUM) to manage VEM software installation for ESX hosts, see the VMware documentation.

•The control and packet VLANs must already be configured on the host to be used for the VSM VM.

•Make sure that the VM to be used for the VSM meets the following minimum requirements.

---

Caution The VSM VM may fail to boot if RAM and CPU are not properly allocated.
This document includes procedures for allocating RAM and setting the CPU speed.

---

VSM VM Component	Minimum Requirement
Platform	64-bit
Type	Other 64-bit Linux (recommended)
Processor	1
RAM (configured and reserved)	2 GB 1
NIC	3
SCSI Hard Disk	3 GB with LSI Logic Parallel adapter2
CPU speed	1500 MHz 3

1 If you are installing the VSM using an OVF or OVA file, then the correct RAM setting is made automatically during the installation of this file. If using the CD ISO image, use the "Installing the Software from the ISO Image" procedure to reserve RAM and set the memory size. 2 Other types of adapters can be used and are dependant on the operating system. 3 If you are installing the VSM using an OVF or OVA file, then the correct CPU speed setting is made automatically during the installation of this file. If using the CD ISO image, use the "Installing the Software from the ISO Image" procedure to set CPU speed.

Upstream Switch Prerequisites

The following prerequisites apply to the switch upstream from the Cisco Nexus 1000V:

•If you are using a set of switches, make sure that the inter-switch trunk links carry all relevant VLANs, including control and packet VLANs. The uplink should be a trunk port carrying all VLANs configured on the host.

•The following spanning tree prerequisites apply to the switch upstream from the Cisco Nexus 1000V whose ports connect to the VEM.

For more information about spanning tree and its supporting commands, see the documentation for your upstream switch.

–On upstream switches the following configuration is mandatory:

cat6k IOS:
(config-if) portfast trunk
or
(config-if) portfast edge trunk

n5k:
(config-if) spanning-tree port type edge trunk

–On upstream switches it is highly recommended that the following are enabled globally:

Global BPDU Filtering

Global BPDU Guard

–On upstream switches where you cannot globally enable BPDU Filtering and BPDU Guard, it is highly recommended that the following are configured:

(config-if) spanning-tree bpdu filter

(config-if) spanning-tree bpdu guard

Guidelines and Limitations

Use the following guidelines and limitations when installing the Cisco Nexus 1000V software:

•Do not enable VMware Fault Tolerance (FT) for the VSM VM because it is not supported. Instead, NX-OS HA provides high availability for the VSM.

•The VSM VM supports VMware high availability (HA). We strongly recommend that you use redundant VSMs and the NX-OS high availability, which can be used with VMware HA. Use the VMware recommendations for VMware HA. The host isolation response must not be set to Leave powered on. For detailed information about this setting, see the VMware high availability documentation.

•Do not enable VM Monitoring for the VSM VM because it is not supported, even if you enable VMware HA on the underlying host. Cisco NX-OS redundancy is the preferred method.

•If either your primary or secondary VSM is installed on the same server as the vSwitch, then a traffic interruption between them can occur when you migrate interfaces to the DVS. In this configuration, both VSMs take the active role, sometimes referred to as split-brain. If this happens, the primary VSM is reloaded when connectivity between the VSMs is restored.

•A single host can be used for both the VEM and VSM that manages it. For information about the VSM configuration, see the Cisco Nexus 1000V Getting Started Guide, Release 4.2(1)SV1(4a)

Installing the Software from the ISO Image

You can use this procedure to install the VSM software using the ISO image file from the CD.

BEFORE YOU BEGIN

Before beginning this procedure you must know or do the following:

•You have already read the "Prerequisites" section.

•You have already manually provisioned the VM to be used for the VSM. For detailed information, see the following VMware document:

vSphere Virtual Machine Administration Guide

•The VSM VM requires the following and this procedure includes steps for updating these properties:

–Minimum of 2 GB of RAM reserved and allocated.

–Minimum CPU speed of 1500 MHz.

•Do not create more than one virtual CPU. The Cisco Nexus 1000V supports only one virtual CPU.
