Hi Veera, I would say, that doing an ftp ftp.some.where would generate traffic based upon the ftp appliaction. All the L7 information is included in the TCP/UDP packet which you are inspecting with your module. Maybe you need to be a bit more specific about what you want to inspect/filter with your module and how.
