This is Sylvester, I've a small question.
I've a network & the traffic from the network is "really" huge.
(IP network - Internal) ------> Cisco 6509 x 2 (HSRP) --------> Firewall ----------------> Router (HSRP) ---> Internet
Now I need to pull a report on firewall for no of applications accessed by Internal guys. For e.g If a guy inside the network access a bit torrent application, i should have log about it. So I was trying to do in firewall, which I couldnt.
So here is my question, Can it be done in 6509 switch? by using NBAR or something else (Netflow)? End of the day, I need it like a report.
1. How much its going to impact my network?
2. Do I need some additional module?
3. Can i pull report from somewhere? Or statistics can be pushed/pulled?
4. Last, but not least. Can it be done?
