CEF ip accounting type function?

I am looking for the TopN traffic through a router. Normally I would use IP accounting, but this is not accurate in a router running CEF. What command would I use to show traffic statistics on a CEF based router?

Hi,

Kindly use NetFlow as follows:

"ip route-cache flow" under the main interface or "ip flow ingress" under the subinterface and then use "show ip cache flow" to display it.

I agree with Mohammed that NetFlow is a very good tool and that it is what you should use. In recent versions of code it is possible to have NetFlow identify the top talkers (makes it much easier than having to interpret the output of show ip cache flow. This link will give you information about this capability:
