I have a client that recently purchased a NAM-2 and he wants to squeeze all the juice from it.
He has a WAN consisting of a few dozens ISR routers, configured to send Netflow data to the NAM.
The NAM does account and report on application/flow statistics based on NDE from the devices, but he would also like to get the interface utilization statistics (ifPacketsIn, ifPacketsOut, ifBytesIn,ifBytesOut) of each router.
He does manage to see on Monitor the overall interface utilization, but it does not discriminate input or output direction.
What would be the best way to do this on the NAM, if even possible? I'm thinking about using RMON, but would netflow also be a possibility?
He's currently running 4.0 code on the NAM.
Thanks for any input.
