The Cisco Nexus 1000V NAM Virtual Service Blade (VSB) provides a virtualization technology that enables a Nexus 1010 switch to host other services and applications. The Network Analysis Module (NAM) 4.2 is one such application that can be hosted on a Nexus 1010 switch.
This chapter contains the following sections:
•About the Nexus 1010 Virtual Services Appliance
About the Nexus 1010 Virtual Services Appliance
The Nexus 1010 appliance must have the following minimum resources available for use as a virtual blade:
•53G disk space
Figure 1-1 shows a NAM Virtual Service Blade deployment scenario using Cisco Nexus 1010.

Before you begin the software installation, ensure that the devices have been physically installed and set up for the following:
•The Nexus 1010 Virtual Services Appliance has network connectivity through an Ethernet interface and is accessible using the serial console.
•The NAM 4.2 VSB software image is available on the Nexus Virtual Services Appliance.
•The Nexus 1010 Virtual Services Appliance has adequate resources available to run NAM 4.2.
The NAM virtual blade software 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.
The Cisco NAM license is used for one Nexus 1010 Virtual Services Appliance. When you obtain the license for the appliance, the license is valid only for the appliance with the PID and SN you provide when you obtain the license.
You can get the PID of the appliance using the show inventory CLI command.
PID: N1K-674-K9 VID: 0 SN: KQEDKRON
Obtaining a License
To obtain a NAM Virtual Service Blade (VSB) license, go to the following URL:
Follow the instructions on this page to obtain a NAM VSB 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 e-mail. 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 a License
To install a license file, use the install license command. See the next section, Licensing Commands, and the Network Analysis Module Command Reference Guide for more information about the install license command.
The following is an example of the install license command:
license install ftp://email@example.com/bin/licenses/NAM_VB_License.lic
In this example, the install license command fetches the license file, NAM_VB_License.lic, from the directory /bin/licenses of the host computer.com.
This section describes NAM CLI commands used to install and manage the NAM VSB license. You can find more details about these commands in the Network Analysis Module Command Reference Guide:
Note Technical documentation for NAM 4.2 will be available on www.cisco.com after this product is released to the public.
license install ftp://<username>@<host>/<path>/<licensefilename>
Use the license install command to install a license file.
Use the show license command to display license information for the evaluation license and permanent licenses.
config upload ftp://<username>@<host>/<path> [configfilename] [licensefilename]
Use the config upload command to upload the license file. The configfilename and licensefilename options are optional.
config network ftp://<username>@<host>/<path>/<filename> <licensefilename>
Use the config network command to restore the license file.

About the NAM GUI
When you click About in the upper right corner of the NAM VSB GUI, a window displays the software and version installed and information about any license currently installed. If a permanent license is installed, the PID and SN of the Nexus 1010 Virtual Services Appliance is also displayed.
The audit trail records any license management activities as well as any modifications to the configuration and other system information. To view the audit trail, click Admin > Diagnostics, then click Audit Trail in the Contents menu.
System Alerts record any alert generated by the NAM. There are system alert messages sent by the NAM as the days pass prior to the expiration of the Evaluation License. System alert messages are sent when there are 20, 15, 10, 5, 4, 3, 2, and 1 days remaining and again when the license expires.
