VLANs are trunked on a single physical interface using trunk mode, which can be bound with other physical interfaces into an etherchannel. Just so we're clear on terminology :)
For QoS, the only place where you can trust is on the physical interface, unless you are using VLAN-based QoS (which relies on the use of policy-maps.) So, generally, you trust cos on the physical interface to the WLC if it is a trunk interface, which it normally is. You cannot apply trust to an Etherchannel (go into a port-channel interface and type "m?" - no "mls" commands.) Jason Boyers - CCIE #26024 (Wireless) Technical Instructor - IPexpert, Inc.
