Introduction

The NAM 4.2(1n) software enhances performance of the NAM Traffic Analyzer on the Nexus 1010 Virtual Services Appliance by increasing throughput for ERSPAN and NetFlow over the management interface.

The Cisco Nexus 1010 Virtual Services Appliance has an integrated Cisco NAM VSB solution to monitor and troubleshoot the Cisco Nexus 1010 Virtual Services Appliance environment. As an integrated solution, the Cisco NAM VSB is ideal for customers who are deploying the Cisco Nexus 1010 Virtual Services Appliance, thereby providing greater investment protection, ease of deployment, and reduced network footprint.

The software enables network administrators to extend operational visibility into the VM network, including interactions across virtual machines. The feature can be used with the Nexus 1010 Virtual Services Appliance, deployed in the Data Center in conjunction with Nexus 1000V switch deployments. NAM supports the use of embedded management features, namely Encapsulated Remote Switched Port Analyzer (ERSPAN) and NetFlow, on the Cisco Nexus 1000V switch. ERSPAN can be configured on the Cisco Nexus 1000v switch to allow NAM to obtain visibility into specific ports or VLANs. NetFlow Data Export can also be configured on select virtual and physical interfaces to provide insight into traffic behavior in the virtual machine network.

Key benefits include:

•Analyze network usage behavior by application, host/VM, and conversation to identify bottlenecks that may affect performance and availability

•Troubleshoot performance issues with extended visibility into VM-to-VM traffic, virtual interface statistics, and transaction response times

•Assess impact on network behavior due to changes such as VM migration, new application deployment, and port profile update

•Improve the efficiency of your virtual infrastructure and distributed application components with comprehensive traffic analysis

As a distinctive advantage, NAM allows monitoring of virtual machines live while they migrate with VMotion.

NAM Virtual Blade Licensing Requirements

The NAM 4.2(1n) software for the Nexus 1010 Virtual Services Appliance requires you to install a product license in the form of a text file. An evaluation license allows you to use the software for up to 60 days, but you will be unable to log in to the NAM GUI after the evaluation license expires. When using an evaluation license, the NAM login window indicates how many days remain before the evaluation license expires.

You can provide licensing information, also known as node-locking information, during software installation or after software installation using the NAM CLI. During the NAM software installation, you will be prompted to enter a product identifier (PID) and serial number (SN).

To obtain a NAM Virtual Blade license, go to the following URL:

http://www.cisco.com/go/license

Follow the instructions on this page to obtain a NAM VB license file. You will need the appliance PID and SN to obtain the license file. After you enter the PID and SN or the Product Authorization Key, a license file will be sent to you by Email. Store this license file on an available FTP server. Use the license install command to install the license after the NAM software installation completes.

Installing NAM Software on a Nexus 1010 Appliance

You will need to remove the existing NAM image, and install Cisco NAM 4.2(1n) from the Nexus 1010 CLI.

Note The NAM does not support High Availability (HA) mode.

Note If you ordered a Cisco Nexus 1010 with NAM, the NAM installation media will already be loaded on the appliance. The installation media consists of an ISO file in bootflash:/repository.

If you have a Cisco Nexus 1010 without NAM software, and you want to add it, you will need to download it from Cisco.com to a local ftp or http server, and then install it using the command copy ftp://path/to/nam/nam.iso bootflash:/repository.

Step 1 Log in to the Nexus 1010 and enter virtual blade configuration mode: 

vsm-nam1# conf t

Step 2 List the contents of the repository. 

vsm-nam1(config)# dir bootflash:/repository

  ... 

  153135104     Jan 24 09:37:17 2011     nam-4-2-1n.iso

  ...


Usage for bootflash://sup-local

   305664000 bytes used

  3685715968 bytes free

  3991379968 bytes total

vsm-nam1(config)#

Use the directory listing to enter the correct ISO file that contains the NAM media.

In the example above, "nam-4-2-1n.iso" is the filename, and the user is using this command to find the nam install media (an iso file found in bootflash:/repository).

Step 3 If an existing NAM image is installed, you will need to remove it (if there is no NAM virtual service blade installed, skip this step and go to Step 4). 

vsm-nam1(config)# virtual-service-blade NAM

vsm-nam1(config-vb-config)# no enable

vsm-nam1(config-vb-config)# no virtual-service-blade NAM

vsm-nam1(config)#

Step 4 To install the new NAM image, enter the virtual service blade creation mode. 

vsm-nam1(config)# virtual-service-blade NAM

vsm-nam1(config-vb-config)#

Step 5 Enter the NAM configuration information.

Note The data VLAN is used for both management and data (packet) collection for the virtual NAM. Unlike the VSM, the virtual NAM does not inherit the management VLAN from the VSB. The IP address assigned to the NAM must be in the data VLAN. 

vsm-nam1(config-vb-config)# virtual-service-blade-type new 

nam-4-2-1n.iso

vsm-nam1(config-vb-config)# interface data vlan 3

vsm-nam1(config-vb-config)# enable

Enter vsb image:[nam-4-2-1n.iso]

Enter Management IPV4 address:  172.20.122.107

Enter Management subnet mask:  255.255.255.128

IPv4  address of the default gateway: 172.20.122.1

Enter Hostname:  nam-vsm1

Setting Web user/passwd will enable port 80. Press Enter[y/n]:y

Web User name:  [admin]

Web User password:  admin

vsm-nam1(config-vb-config)#

Step 6 The NAM VSB installation will begin. You can use the show virtual-service-blade summary command to see the installation in progress. 

vsm-nam1(config-vb-config)# show virtual-service-blade summary

Step 7 When the status says "POWER ON," you can log into the NAM console.

Note The default password is "root." 

vsm-nam1# login virtual-service-blade nam

Telnet escape character is '$'.

Trying 127.1.0.18...

Connected to 127.1.0.18.

Escape character is '$'.

Limitations and Restrictions

This release for NAM is supported only on Cisco Nexus 1000V Release 4.2(1)SV1(4) releases.

NetFlow Records from the NAM (Nexus 1000V NAM Virtual Service Blade)

On the Nexus 1000V NAM Virtual Service Blade, NetFlow record-related CLIs will send NetFlow record types below, which can be decoded properly by NAM. If you define your own record, it may not be decoded by NAM. This pre-defined collection of records offered by this CLI will work for most customers. Under "flow monitor" section as below 

flow monitor YourMonitorName

  record netflow-original

record netflow-original" will send NetFlow records that can be decoded properly by NAM.

MIB Limitation

Due to a Nexus 1010 Virtual Services Appliance MIB limitation, NAM Release 4.2 can't display the following information when "Managed Device" is VSM:

•Port Stat (at Monitor > Managed Device > Port Stats)

•Managed device health (at Monitor > Managed Device > Health)

ACS Version Supported

The only ACS server version supported is 4.2.
