Configuring the Network Analysis Module
This chapter provides information about the integration of the Cisco Network Analysis Module (NAM)
in the WAAS Central Manager and describes how to configure and use the NAM.
This chapter includes the following sections:

Information About NAM Integration
WAAS is enhanced with application performance monitoring capabilities when you integrate the WAAS
Central Manager with the Cisco Network Analysis Module (NAM) Traffic Analyzer software.
The NAM Traffic Analyzer software enables network managers to understand, manage, and improve
how applications and services are delivered to end users by combining flow-based and packet-based
analysis into one solution. With the NAM, you can perform traffic analysis of applications, hosts, and
conversations, make performance-based measurements on application, server, and network latency, and
use Quality of Service (QOS) metrics for network-based services and problem analysis using packet
captures. The Cisco NAM includes an embedded, web-based Traffic Analyzer GUI that provides quick
access to the configuration menus and presents easy-to-read performance monitoring and analysis on
network traffic.
The architecture for WAAS Central Manager and NAM integration has the NAM deployed as a virtual
blade in one of the data center WAEs. While this deployment eliminates the need for separate hardware
in Proof of Concept (POCs) deployments, users are not limited to this deployment and can deploy
NAM 5.1 in any form factor such as virtual blade, physical blade, or appliance.
Prerequisites
The NAM integration has the following prerequisites:
• The WAAS 4.4.1 or later Central Manager is installed and configured.
• The NAM 5.1 hardware and software are installed.
