I am thinking about configuring a netflow system under my network, and I have some questions about configuring a Cisco 6500.
Can I just configure the switch part with netflow, (not the router part) ? Because if the only problem is that it will miss the first packet in the flows accounting, I won't matter, and the configuration will be really easier !
Another question : is the netflow caching managed by hardware or by software ? And so does netflow impact the CPU load ?
