I've looked at Cisco's VoWLAN Design Guide v4.1 and it has quite a bit of info for Vocera. The controller setup with a multicast address and the WLAN features to properly classify voice traffic is clear to me. I have 'mls qos trust dscp' on all of the AP interfaces. What is missing for me is what setting I place on the trunk ports directly connected to my WLC 4402. Is this where I change to 'mls qos trust cos' or do I leave it 'mls qos trust dscp' and use something like 'auto qos' to create my queues? Or even yet, do I create a policy map and manually map Cisco's Voice DSCP of 6 to 802.1p EF/46?
