I am new to this forum and hope that you can help me with my question. I need to get the ip flow top talkers that are using bittorrent. I have created class map to match bittorrent application and matched it at ip flow top talkers. But when i ran the show ip flow top talkers command, it shows that it didn't match the traffic although show ip nbar protocol-discovery shows that some one on the network is using bittorrent. I am using cisco2821 IOS 12.4. I really appreciate your help.
