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.
access-list 2000 permit udp any eq 3479 any
access-list 2000 permit udp any any eq 3479
access-list 2000 permit udp any eq 5199 any
access-list 2000 permit udp any any eq 5199
access-list 2000 permit udp any eq 5060 any
access-list 2000 permit udp any any eq 5060
Class-map match-any VOIP-Priority-Traffic
Match access-group 2000
Policy-Map Packet-Queueing
Class VOIP-Priority-Traffic
Priority percent 33

Hello Mitchell,
may you add the configuration of the DSL ATM interface, BVI and show ver | inc image?
I'm afraid you are in trouble here.
Hope to help

Hi,
Not sure if you have NAT or crypto on WAN interface, if you do then it might be the reason you dont see packet matches.

ATM0
interface ATM0
no ip address
pvc 0/35
encapsulation aal5snap
dsl operation-mode auto
bridge-group 1
service-policy output Packet-Queueing
BVI1
