Prerequisites

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

VSM Prerequisites

VMware and Host Prerequisites

Upstream Switch Prerequisites

VSM Prerequisites

The following prerequisites apply to the VSM:

We recommend that you install redundant VSMs. For more information about configuring redundant VSMs, see the Cisco Nexus 1000V High Availability and Redundancy Configuration Guide, Release 4.0(4)SV1(3).

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, see the Cisco Nexus 1000V Getting Started Guide, Release 4.0(4)SV1(3).

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

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 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 4.0(4)SV1(3).

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

VMware and Host Prerequisites

The following prerequisites apply to VMware and the host:

You have already installed the vCenter Server.

You have already prepared the vCenter Server using the instructions from VMware.

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

You have already prepared the required hosts, including the following:

The VMware Enterprise Plus license must already be installed on the hosts.

All VEM hosts must be running ESX or ESXi software version 4.0 or higher.

There is at least one ESX or ESXi host running version 4.0 or higher. If you plan to use VMotion, you need two hosts running version 4.0 or higher.

An ESX host is available to run the VSM VM.

The VSM virtual machine can be hosted on any of the following:
- A VEM in an ESX host that it is managing.
- A separate ESX or ESXi host (3.5, 4.0, or 4.1) running the regular VMware vSwitch or DVS.
- The same host running VEM but using a VMware vSwitch or DVS.

The ESX host requires a minimum of 4 GB of physical RAM to host a VSM VM as the ESX server alone requires a minimum of 2 GB of physical RAM. Additional memory may be required to run the vCenter Server VM on the same host.

Do not create more than one virtual CPU for the VSM VM. The Cisco Nexus 1000V only supports one virtual CPU.

Each host has a minimum of the following physical NICs (PNICs):

One PNIC for a Service Console or Management.

One PNIC for the traffic between VSM and VEM and for VM data traffic.

All ESX hosts that are to be added as modules in a Cisco Nexus 1000V 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 ESX host.

On the host running the VSM VM, the control and packet VLANs are configured through the VMware switch or DVS and the VMNIC.

The optional VMware Update Manager (VUM) manages the Cisco Nexus 1000V VEM software installation for ESX hosts in a data center. For instructions on installing VUM on the vCenter Server, see the VMware documentation.

The VSM VM control VLAN needs to be enabled on both of the following:

The port group or port profile that is connected to the control interface on the VSM.

The system uplink port profile.

You have completed configuring valid network mapping for control, management, and packet VLAN access.

The host for the VSM VM runs on 64-bit server hardware and can run VMware software version 4.1, 4.0, or 3.5.

To install the VSM software, you can use either of the following methods:

Attach the VSM ISO image to the VM virtual CD-ROM.

Use the following open virtual appliance (OVA) file:

Nexus1000v-4.0.4.SV1.3a.ova

Make sure that the VSM VM meets the following minimum requirements:


Caution The VSM VM may fail to boot if you have not properly allocated RAM and CPU.

1 If you are installing the VSM using the OVA file, then the correct RAM setting is made automatically during the installation of this file.

If using the CD ISO image, use the "Allocating RAM and Setting the CPU Speed for the VSM VM" procedure to reserve RAM and set the memory size.

2 If you are installing the VSM using the 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 "Allocating RAM and Setting the CPU Speed for the VSM VM" procedure to set CPU speed.


Upstream Switch Prerequisites

The following prerequisites apply to the switch upstream from the Cisco Nexus 1000V whose ports connect to the VEM:

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

For more information about these features and commands, see the documentation for your upstream switch.

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. When using VMware HA, you must follow the VMware recommendations. The Isolation Response must not be set to Leave powered on.

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.

Allocating RAM and Setting the CPU Speed for the VSM VM

Use this procedure and your VMware documentationto reserve RAM and set the memory size and CPU speed for the VSM VM if you use the CD ISO image to install the VSM.


Note If you install the VSM using the OVA file, then the RAM and CPU speed are automatically set and you do not need to use this procedure to make those settings.


BEFORE YOU BEGIN

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

The VSM VM requires a minimum of 2 GB of RAM reserved and allocated.

The VSM VM requires a minimum CPU speed of 1500 MHz.

This procedure requires the VSM VM to be powered off.

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