Thank you for the information! Actually I have some issues with my ASDM... It freezes after you launch it and put in the username and password. It just stopped. Then if you restart the ASA it will fix it but after days the problem will happen again!! I have tried different Java version but no help. I am using ASDM version 6 and maybe I should think of updating to version 7 if there is one!

So is there an equivalent command in CLI for this top 10 sources IP? Thanks a lot!

I rarely use ASDM too. I don't know a command off the top of my head, but let me look around.

thank you! I appreciate

I haven't been able to find an ASA command, but here is one way.

Thank you!

make sure your java version is not above Version 6 update 7, if so you will need to downgrade. I updated by asdm to 6.1(5)51 and my ASA to 8.0(4) and that also seemed to help out with stability.

Difan,

For future reference, a new feature was introduced in latest asa version code 8.2.x called netflow, it was only supportted on the 5580 platform but under this code is now supported on ALL ASA5500 series. Configure netflow under this code if you ever upgrade to it,find a free netflow collector out there, thus you can capture traffic flows per source/destination traversing your firewall as you would in a router.
