I'm trying to get a fairly simple QoS policy up and running on my DSL line using a Cisco 877. My aims are fairly simple - make sure that realtime and management stuff like RTP and SSH works regardless of congestion, then make sure that HTTP, FTP, SMTP etc. protocols get a good shout in times of congestion and throttle back things like bittorrent when things get busy.

I've tried applying the config below, but it seems to have no effect. If I pull down a couple of ubuntu torrents, and also download a large file via HTTP, the HTTP download slows to a crawl, whereas the torrents merilly carry on downloading at 300kbps+. The only effect it seems to have is upstream bittorrent slows to about 0.1kbps.

My understanding is that I need to have a policy applied outbound on my ATM subinterface, and inbound on the VLAN so the router knows how to deal with the different packets flowing in both ways. I tried adding a police only policy inbound on the ATM subinterface, but again, this seemed to make no difference. Bittorrent incoming traffic romps over everything.

Oddly, no matter how much I try and configure it, I can't get the Packet-Queueing policy to show up outbound on the ATM0.1 interface. The inbound one shows up fine.

Any ideas?
