Are all Cisco products using the same CLI configuration to enable NetFlow?

You won't be able to implement NetFlow across the board on those platforms with that command set. >#ip route-cach flow was replaced by ip flow ingress to allow for ip flow egress as well. Otherwise what you have should work on the 7Ks. For the 12406 see the command ref and for the cats see this tech ref. http://www.solarwinds.com/support/Netflow/docs/OrionNetFlowSwitches.pdf

This is really helpful! I will further study this and try it later on.

Thank you!

Further questions:

1. Version 5 and version 9 of NetFlow, which 1 is most recommended? Which 1 will most likely take a toll on the CPU utilization of the device?

2. Assuming a device has peak CPU and Memory utilization (according to NPM) of 80% and has 500+ interfaces, where 40 interfaces would be enabled with Netflow and monitored by NTA. Is this advisable? Any workarounds?

What I would do is choose the most important interfaces and apply NetFlow there and watch memory and CPU. There is no performance benefit between v5 and v9.
