In a pretty naked marketing attempt, the following objective appears on the outline:
- Describe the features and operation of network analysis modules on Catalyst switches to improve network traffic management
Most of what I found on this is from the Network Analysis Module (NAM-1/NAM-2) page. The NAM 1/2 data sheets provide more information on what this really does.
It’s actually pretty simple. Switches, by default, support RMON. Routers also support NetFlow Export, which allows for layer 4 statistics to be obtained.
The NAM serves two main purposes. One is to listen on the backplane of the Catalyst 6500 and gather statistics. An on board web server lets you view them. The NAM can also collect netflow statistics from other devices. These NAMs can also report up to thenGenius Real-Time Monitor, part of CiscoWorks Lan Mananagement.
As it pertains to the exam, I’m not sure what can be asked about the product other than basic features. I’d suggest reading through the data sheet, and be familiar with RMON and NetFlow concepts.
