Cisco’s Network Analysis Module collects and analyzes network traffic. Device is embedded PCs that collect and present traffic and statistics on network operation. The NAM is unique because the monitored traffic moves directly onto the blade from the Catalyst backplane, is analyzed, and can then be viewed simply by using the embedded Web interface. I would love to install a NM-NAM in my 2651XM router to test its functionality. This is just the sort of device that would make a great addition to my next book.”]
