I'm running an 877W at home and I'm trying to configure QoS on my downstream link. The theory is if I set my downstream bandwidth to 80% of the link speed, the choke point is under my control and I can choose what gets discarded. It works just fine on the Linksys that I just replaced (google wondershaper if you're curious).
I have my upstream service policy working fine on the dialer interface, but cannot figure out how to apply one downstream. Obviously I can't apply queueing inbound on the dialer interface and my ethernet and wireless interfaces are bridged together with IRB. I don't want to apply the QoS on the hardware because I have 2 downstream interfaces (so how do I split the bandwidth?) and I don't want to limit ethernet to wireless traffic. I've tried applying both LLQ and GTS policies to the BVI and the interface will accept neither. I've also thought about marking the packets inbound and then applying something like WRED downstream but again this won't work on the BVI. I really don't want to rate limit my classes as this won't allow efficient use of the bandwidth when there is no congestion.
Any suggestions please.
