A customer is looking for a way to analyze bandwidth utilization on Cisco router interfaces - specifically, how much (and what percentage) of BW is being used by:
- applications - HTTP(S), P2P, etc.
- L3 - which particular sources and/or destinations are consuming the most BW
I know the Cisco interface commands (which only provide traffic volume over different periods of time.
Will Netflow provide this, or is a 3rd-party application required? We need to provide a recommendation to the customer that they can use to pull this information on-demand, and that's relatively easy-to-use and cost-effective (if not built-in/free).
Thanks, and reference docs/links are always appreciated.
