Cisco Branch Routers Series Network Analysis Module 4.1
Overview
Q.
What is Cisco
®
Branch Routers Series Network Analysis Module (NAM)?
A.
Cisco Branch Routers Series NAM is a powerful network-aware performance monitoring solution that delivers
unparalleled insight into application performance and network traffic to help ensure the consistent and efficient
delivery of applications and services to end users. It provides visibility into how applications are performing and
how users are experiencing the services being delivered over the network. It enhances the performance of the
empowered branch with integrated manageability, improved service quality, and operational effectiveness.
The unique design of Cisco NAM combines a rich set of embedded data collection capabilities and performance
analytics with a remotely accessible, web-based management console, all of which reside on a single network
module that is installed into Cisco 3900 Series, Cisco 2900 Series, Cisco 3800 Series or Cisco 2800 Series
Integrated Services Routers (ISRs), or Cisco 3700 Series Multiservice Access Routers (MSRs). Cisco NAM
includes a Traffic Analyzer GUI, which provides quick access to the configuration menus and both real-time and
historical performance reports.

Transaction-aware application
response time monitoring
response time monitoring
Analyzes TCP-based application packets as they travel from the client through the network to the data center and
out again, providing insight into network round-trip time, server response time, data transfer time, transaction time,
and so on, to improve application performance.

insightful data analysis
Captures the packets 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 viewed through the Traffic Analyzer GUI while the data is
still being captured. Extensive capture features, including trigger-based captures, decodes, filters, and a capture
analysis toolset, help to quickly pinpoint and resolve problem areas.

Secure solution
Offers TACACS+, Secure Sockets Layer (SSL), and Secure Shell (SSH) Protocol-based security.
Deployment flexibility
Cisco NAM can be deployed in blade form factor in Cisco Catalyst
®
6500 Series Switches, Cisco 7600 Series
Routers, and Cisco Integrated Services Routers, as multigigabit appliances, and as a virtual blade residing directly
on WAAS devices. The complement of physical and virtual blades and of appliances allows NAM instrumentation to
be broadly deployed in the network for comprehensive performance monitoring.
