I have a lot of 3430 routers on metro-e type scenarios and QOS is not working correctly. Has anybody had problems with the 10.8 code and QOS.
I have done some extensive testing and it appears that QOS is working as it is hitting the qos maps but I can completey kill a VOIP DSCP 46 call across the WAN.
I have tested this on 10mb metro-e and on a single T1 with the same results. I currently have a strict policy to limit the normal data traffic so that it cannot overwhelm the links.
This is happening on several of my customers networks.

Still working this with Support.
Thank you for asking this question in the support community. Is it possible you can reply with the current configuration (please, remember to remove any information that might be sensitive to the organization)? I will be happy to review the configuration and application and hopefully provide some recommendations. Also, do not hesitate to reply with any additional questions or information. I will be happy to help in any way I can.

I have tried with the traffic shape command on the interface and without and of course it has made no difference. Currently the traffic shape command is on the WAN (metro-e) interface. It is a 10mb pipe and we limited to 9.5mb as they are giving us no headroom.
