I have upgraded a Cisco 4506 with a Supervisor 4 to a Supervisor 6-E and low & behold, my CoS/QoS settings no longer work. I see from a white paper that Cisco upgraded the supervisor capabilities to MQC, which is more inline with the IOS routers. There are a couple differences though. Does anyone have any links or other tips that is not covered in white paper?
I'm having a hard time converting my previous 4500 QoS settings for voice (Avaya phones) to the new syntax on the Supervisor 6-E. I used a Cisco Press book called End-to-End QoS Network Design, but being a few years old it doesn't include the latest Sup 6 from the 4500's.
