I have a 4507R-E chassis with Supervisor IV running IOS 12.2(50)SG. I am trying to configure "auto qos voip trust" on some of the uplink ports. When I try to configure it on a port that is in a channel group, I get the error "AutoQoS Error: AutoQoS can not be configured on member port(s) of a port-channel". I have also tried configuring it on the channel interface, but it is not an available command under the channel interface. Is there a way to do auto qos on the channel interfaces or their member ports or does it have to be configured manually?
