Hi,
We are trying to investigate ways of blocking torrent traffic on our WLANs and currently testing the AVC feature on a pair of 5500 WLCs running 7.4.100.
WLAN traffic is anchored from a "Campus" WLC to a "DMZ" WLC. An AVC profile was created on each WLC to Drop "bittorrent" and "encrypted bittorent" traffic and was applied on the WLANs.
A laptop was configured with 2 torrent clients (utorrent and bittorrent).
Following extensive testing we came up with the following results:
- The foreign WLC is not able to identify the applications running over the wireless traffic. AVC is properly running on the anchor WLC.
- When using the utorrent application, the anchor WLC was able to categorize the traffic as bittorrent traffic. On the other hand torrent traffic was not blocked and after downloading a 70MB file on the laptop, AVC reported only 500Kb of bit torrent traffic
- When using the bittorrent application, traffic was blocked successfully.
Has anybody been able to successfully block torrent traffic using this feature on a production network?
Are there any commands to identify the amount of packets denied by the AVC policy?
Thanks,
Theo
