Top XX Receivers and Top XX Transmitters showing the EXACT same data/graphs

Question

We are monitoring our internet traffic (via our Cisco ASA).  I am monitoring the inside interface of the ASA.  My Top XX Receivers and Top XX Transmitters graphs are showing the exact same data.  However, if I go to historical reports and view the top 50 receivers and top 50 transmitters reports, I get the actual data for each (the reports are not the same as each other, which is obviously how it should be).

Any ideas?

Hi nerditup,

I guess it's caused by the fact that ASA produces bi-directional flows. Here the good post about it http://www.plixer.com/blog/asa/everything-you-didnt-want-to-know-about-bidirectional-and-unidirectional-netflow/

thanks
