It looks for the protocol (connections) and then you can act on it how you'd
like. You won't get to the transfer part (I've tested this on the
production example below).

My example drops all off the protocol.

class-map match-any P2P
 match protocol bittorrent
policy-map FilterSerial
 class P2P
   drop
 class class-default
  fair-queue

7200-1#sh policy-map int s1/0
 Serial1/0

  Service-policy output: FilterSerial

    Class-map: P2P (match-any)
      385977 packets, 36127142 bytes
      30 second offered rate 0 bps, drop rate 0 bps
      Match: protocol bittorrent
        335633 packets, 31460997 bytes
        30 second rate 0 bps

7200-1#sh ip nbar pdlm
The following PDLMs have been loaded :
disk1:bittorrent.pdlm
disk1:directconnect.pdlm

7200-1#dir disk1:
Directory of disk1:/

    1 -rw- 24595288 Aug 03 2007 06:03:52 -05:00
c7200-ik9o3s-mz.123-14.T7.bin
    2 -rw- 3100 Jun 10 2008 11:16:18 -05:00 bittorrent.pdlm
    3 -rw- 2251 Jun 10 2008 11:17:20 -05:00 directconnect.pdlm

Just be careful with NBAR. Make sure you have protocol discovery on and
make SURE you test. NBAR isn't 100% bug free.

Hi experts
I am trying to achieve to limit or drop torrent files via NBAR. After a
search
I found bittorrent.pdlm
I am trying to install this in my router.
What I would like to know is "Is this pdlm use to limit or drop all torrent
files or bittorrent only?"
because so many software avaliable to download files via torrent example
bitcomet, utorrent, etc......
I appreciate your input.
Thanks
Li
