Dear Tech Guy,

 

I came across this page while I was searching for something else entirely ;-)

I was for sure that someone must have provided you with the right answer. Sadly they haven't. You can not block torrent using port numbers as any torrent client allows you to use custom port numbers.  So let me guide you I have successfully done so in my production environment till now.

 

The commands are from an ISR 2811. Details are below

 

System image file is "flash:c2800nm-adventerprisek9-mz.151-4.M10.bin"

 

config goes as below

class-map match-any SCAVENGER
match protocol Konspire2b
match protocol bittorrent
match protocol directplay
match protocol edonkey
match protocol fasttrack
match protocol gnutella
match protocol kazaa2
match protocol webster

 

policy-map TRAFFIC
class MANAGEMENT
bandwidth percent 50
class SCAVENGER
drop
class class-default
fair-queue

 

interface FastEthernet0/0
service-policy output TRAFFIC

 

Works good enough till now.
