netflow dynamic top talkers unavailable

[baracus11]

I have an 1841 router that I enabled the netflow and NBAR on. I can view the protocol traffic from SDM, however, the "Top Talkers" option is not available due to the IOS. What IOS do I need to have this option. Or, how can I find out which ip is using certain protocols/apps?

Thanks for the help

It was introduced with 12.3(11)T and later IOS

What's your current IOS and Feature Set?

HTH,
