Chapter 2 Outline

Hopefully, Chapter 1 introduced the need and benefit of having visibility into the packet steams traversing the

network. In this chapter, we re-introduce the Network Analysis Module (NAM) as a powerful integrated

network monitoring tool designed to give network managers more visibility into their network than ever

before. The innovative design of the NAM combines Simple Network Management Protocol (SNMP) agent

functionality with a Web-based management console, all of which resides on a single blade in the Cisco 6000

series Catalyst switch or Cisco Branch Router series. The NAM architecture combines standard SNMP

agent features with full Remote Monitoring (RMON) 1 and 2 collection as well as other Management

Information Bases (MIBs) such as Application Response Time Monitoring (ART), virtual LAN (VLAN) Switch

Monitoring (SMON), Differentiated Services Monitoring (DSMON), Voice over IP (VoIP), and Network-Based

Application Recognition – Protocol Discovery (NBAR-PD) to provide more comprehensive instrumentation of

voice and data networks. By implementing this functionality in supported switches and routers, Cisco offers

you visibility into your network end to end through all seven layers of the Open System Interconnection (OSI)

protocol stack.

This section is based on the features found in the integrated NAM Traffic Analysis Software v3.5 which can

run on all models of NAM hardware (WS-SVC-NAM-1, WS-SVC-NAM-2, and NM-NAM).

Please note that this chapter does not cover all configuration options of the NAM. Refer to the NAM User

Guide for more details on configuring the NAM to meet your specific needs. If you intend to use this tutorial

as a primer for the actual use of the NAM, Cisco recommends that you first install the product so that you can

follow along. Refer to Chapter 3 for deployment scenarios that offer NAM solutions to real-world problems,

Chapter 4 for installation tips, and the NAM Installation Guide for step-by-step installation instructions. (Links

to the NAM Installation and User Guides can be found in Chapter 5.)

Note(s):

• Cisco Catalyst® 6500 and Cisco 7600 Series Network Analysis Modules will be referred to, in this

tutorial, as the Cat6500 NAM(s), NAM-1, NAM-2 or NAM-1/2.

• Cisco Branch Routers Series NAM will be referred to, in this tutorial, as the NM-NAM.

• The term NAM refers to all modules, NAM-1, NAM-2, and the NM-NAM.
