I am currently setting up a 877 model DSL Router to use with a VOIP phone system. I am needing to setup QoS for the phone traffic to give certain udp ports priority going over the dsl. I have my ATM0 interface in bridge-group 1 and I have the BVI1 inteface configured. Internet service works until I try to apply the "Service-Policy out" command to the BVI1 interface. Once I do apply it to that interface and the internet service goes down, I then do a show run policy-map interface BVI1 and I can see where it is getting packet matches. Only thing is the internet no longer works. If I try to instead apply the QoS to the ATM0 interface, the internet stays up but when I do show run policy-map int ATM0 there are no packet matches. It is if the QoS does not work on that interface. Any suggestions? Below are some of the QoS configurations. Thanks.
