Hi Ivan

Thanks for your reply.

For the Netflow, is it a free S/W? or i should purchase it ??

also is there any configuration needed on the router ?

thanks

Mohamed,

this is a configuration example for NetFlow I found on CCO - http://www.cisco.com/en/US/docs/ios/12_1/switch/configuration/guide/xcdnfc.html

but I belive there should be more practical articles  on the Web, so you won't be lost.

Generally, NetFlow is a IOS/IOX feature, so you don't need to buy it, just configure the router. However, if you would like to collect the statistics on a central location, you most likely will need a piece of software called 'NetFlow Collector', which is not necessarily free.

I hope you've got the direction.

Best regards,

Ivan.
