Cisco Network Analysis Module Software 3.5
PRODUCT OVERVIEW
The Cisco
®
Network Analysis Module (NAM) is a powerful integrated network monitoring solution designed to give you more visibility
into your network than ever before. It shows you what applications are running on your network and how they are performing, to help you
proactively resolve problems before they affect users, plan for changes in resource usage, and manage valuable network resources. Because
the Cisco NAM provides visibility for unparalled traffic monitoring and simplified troubleshooting, it is ideally suited for today’s dynamic,
evolving enterprises.
The innovative design of the Cisco NAM combines a rich set of embedded data collection and analysis capabilities with a remotely
accessible, Web-based management console, all of which reside on a single blade that is easily installed into Cisco Catalyst
®
6500 Series
Switches, Cisco 7600 Series Routers, or Cisco Integrated Services Routers. The Cisco NAM’s embedded Web-based Traffic Analyzer
console offers quick access to configuration menus and presents easy-to-read performance reports on data, voice, and video traffic. The
Cisco NAM provides not only the ability to analyze packets, but also the ability to analyze them from within the switch or router itself,
giving you clear insight into how the network is being used and how your users experience the services the network offers.
Table 1 lists the key features of the Cisco NAM.

Description
Traffic analysis integrated in the switch or router
The Cisco NAM can be deployed in existing Cisco Catalyst 6500 Series Switches, Cisco 7600 Series
Routers, and Cisco Integrated Services Routers, providing greater investment protection, lower total cost
of ownership, and reduced footprint to save premium rack space.

of ownership, and reduced footprint to save premium rack space.
Robust monitoring for LAN and WAN in one solution
Provides visibility into traffic from local and remote switches and routers using a variety of data sources,
such as Switch Port Analyzer (SPAN) and NetFlow, for comprehensive traffic monitoring.

Easy-to-access traffic analysis
Includes an embedded Traffic Analyzer Web interface that can be accessed from any desktop, eliminating
the need to send personnel to remote sites or haul large amounts of data to the central site.

Comprehensive network and application monitoring
Automatically identifies hundreds of protocols and provides real-time and historical performance reports on
the hosts, conversations, and applications using critical network resources.

Captures and decodes the packet to help resolve acute problems before they affect users. Captures can
be performed using a Web browser from any desktop, and the decodes can be readily viewed through the
Traffic Analyzer GUI while the data is still being captured. Captures can also be triggered based on
thresholds.

Built-in application response time monitoring
Tracks response times to pinpoint application problems to the network or to the server.
Advanced monitoring for IP-based services
Analyzes VoIP traffic in near real-time and provides notification on when call quality fails to meet a user-
defined quality threshold. Monitors differentiated services for VoIP and other critical traffic to help validate
and tune planning assumptions and QoS allocations, and to detect incorrectly marked or unauthorized
traffic.

Secure solution
Offers TACACS+, Secure Sockets Layer (SSL), and Secure Shell (SSH) Protocol-based security.
Rich data source for Cisco PVM
Serves as a rich source of data for Cisco Performance Visibility Manager (PVM), a centralized performance
management software application. Cisco PVM collects data from multiple Cisco NAMs to provide a
centralized view of network performance, correlate application response times, localize the cause of
performance problems, and account for the impact of other traffic on performance.

Trace data source for Cisco AAS
Serves as a source of data for the Cisco Application Analysis Solution (AAS). Cisco AAS can collect traces
from the Cisco NAM to help model and predict application performance under varying configurations and
network conditions to facilitate network planning decisions.
