Cisco Catalyst 6500 and Cisco 7600 Series, NAM-1/2
With the NAM, Cisco offers a solution that provides network visibility while also addressing many of the
network and performance monitoring issues that have been raised. What is the NAM exactly? The Network
Analysis Module (NAM) for Cisco Catalyst 6500 series switches and Cisco 7600 series Internet routers,
referred to herein as the Cat6500 NAM, is a network monitoring system that combines a rich set of
embedded data collection and analysis capabilities with a web-based management console. And all of this
functionality resides in a single module. In addition, the NAM has dedicated resources for all management
functions, thus eliminating any load it might impose on the host switch. Now, large volumes of performance
data can be gathered about the switch and the traffic traversing it without impacting the switch itself.
What does the NAM look like from the inside? Well, it is basically a fully integrated management system that
gathers information at the packet level for any interface, VLAN, or Cisco Ether Channel® tunnel on the
switch. It includes embedded Traffic Analyzer software that analyzes and stores the data using both
standards-based and proprietary MIBs (Remote Monitoring, DiffServ Monitoring, Switch Monitoring,
Application Response Time Monitoring, and VoIP Monitoring). The value of each of these MIBs will be
explained throughout the tutorial.
The NAM also hosts an embedded Web server that presents the configuration menus and traffic reports
generated by the Traffic Analyzer software to clients using a supported Web browser. These reports can
provide visibility into voice or data traffic, VLANs, DiffServ configurations, hosts, conversation pairs,
application usage, or application response times. With the NAM, you have the ability not only to collect
packets, but to collect them from the switch itself, giving you the flexibility and visibility to see into the
smallest details of how your switch and your network is being used and how your users experience the
services your network offers.
