Cisco Branch Routers Series

Network Analysis Module (NME-NAM-120S)

Installation and Configuration Note, 4.0

OL-14942-02

Revised Date: October 29, 2009

The Cisco Network Analysis Module (NAM) is an integrated module that enables network managers to understand, manage, and improve how applications and services are delivered to end-users. The NAM offers flow-based traffic analysis of applications, hosts, and conversations, performance-based measurements on application, server, and network latency, quality of experience metrics for network-based services such as voice over IP (VoIP) and video, and problem analysis using deep, insightful 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 reports on Web, voice, and video traffic.

The NME-NAM-120S is the most recent NAM model offered for the branch routers. The NAM software runs on the NAM and is is directly reachable as an end-station and includes its own SNMP agent, HTTP server and command-line interface (CLI). The NAM software communicates with the IOS software on the router.

Table 1 lists the different NAM models.

Note This document specifically addresses the NAM NAM 4.0 software installation and configuration with the NME-NAM-120S, but also supports the NM-NAM, NME-NAM, and the NME-NAM-80S. There are some exceptions noted for NM-NAM commands.
