WAAS provides a virtualization platform or Virtual Blade (VB) technology that enables a WAE device to host other services and applications. The Network Analysis Module (NAM) 4.1 is one such application that can be hosted on a WAE. This enables you to deploy fewer hardware devices to conduct a Proof of Concept (POC), while providing the added benefits of before-and-after reports to demonstrate the impact of WAAS.
NAM 4.1 virtual blade software supports the following WAAS appliances:
•WAVE-574 (with minimum 3 GB RAM and 60 GB hard disk, 6 GB RAM and 180 GB hard disk for three VBs)
•WAE-674 (with minimum 4 GB RAM and 120 GB hard disk, 8 GB RAM and 200 GB hard disk for three VBs)
The best location to install the NAM VB is on the Data Center WAE, as shown in Figure 1-1. If the Data Center WAE does not support Virtual Blade technology, the NAM VB can be installed on any of the Branch WAEs that do support Virtual Blade technology.
Figure 1-1 NAM VB in Data Center
Note Cisco does not recommend forwarding flow agent data from the Data Center to a particular branch.
Before you begin the software installation, ensure that the devices have been physically installed and set up for the following:
•The WAE platform supports Virtual Blade technology
•The WAE device has network connectivity through an Ethernet interface and is accessible using the serial console.
•The WAE device is running an image that supports Virtual Blade technology (such as version 4.1.1 and above).
•The WAE device has a virtual blade license installed and enabled.
•The NAM 4.1 virtual blade software image is available and accessible on an FTP server.
•You have a list of the test server-application pairs for which response time reports are needed.
In addition to the required WAAS virtual blade license, Cisco NAM virtual blade software requires you to install a product license. After you install the NAM VB software, an evaluation license allows you to use the NAM VB software for up to 60 days. However, 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.
Note The Virtual Blade does not require a license for the 60-day evaluation period.
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).
The Cisco NAM Virtual Blade license is used for one WAAS appliance. When you obtain the license for the WAAS appliance, the license is valid only for the WAAS appliance with the PID and SN you provide when you obtain the license.
When you install NAM virtual blade software on the WAAS appliance, you will be prompted to enter the product identifier, serial number, and VID of the WAAS appliance. (You can skip the VID.) If you do not enter the PID and SN at this time, you can do so after the software installation has completed using the NAM CLI.
You can get the PID of the WAAS appliance using the show inventory WAAS CLI command.
PID: WAE-674-K9 VID: 0 SN: KQEDKRON
Obtaining a License
To obtain a NAM Virtual Blade license, go to the following URL:
Follow the instructions on this page to obtain a NAM VB license file. You will need the WAAS 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 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 VB licenses. You can find more details about these commands in the Network Analysis Module Command Reference Guide:
pid-sn PIDxxxx SNxxxx
Use the pid-sn command to enter the WAAS appliance PID and SN after you have installed NAM VB software.
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.
Obtaining Licensing Information
This section describes how to obtain current NAM VB licensing information for a WAAS appliance. You can obtain licensing information the following ways:
•Clicking About in the NAM Virtual Blade GUI; see About the NAM GUI
•Checking the audit trail; see Audit Trail
•Checking the system alert; see System Alert
•Using the show tech command; see show tech Command
About the NAM GUI
When you click About in the upper right corner of the NAM VB 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 WAAS appliances are 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.
show tech Command
The show tech CLI command contains a license information section that displays information about the license type and license status.
You can also view the output of the show tech command from the NAM VB GUI by clicking Admin > Diagnostics > Tech Support. To locate the license information, search for licenseinfo.
