Hi,


I would like to know that there are so many network monitoring 'software' tools out there, why should one go for NAM 'hardware' module. What are the additional benefits.

I'm not in sales (clearly), but the NAM product overview pages can answer this question:

For example, if you're looking to replace a software solution with a 6500-based NAM, here is the data sheet which lists the specific NAM benefits:

From my perspective, having a dedicated piece of hardware always deployed on the network which allows me to quickly monitor my core traffic from remote -- and quickly change what I'm monitoring (be it VLAN, port, RSPAN, etc.) -- is a great advantage. If I see a problem in my lab, I don't have to worry about going do there to put a sniffer on a port. I can just setup a SPAN on one of my NAMs, sniff the traffic, look at my top talkers, etc. It's quite convenient.
