No, "priority-queue out" is a seperate command and does not get enabled by "mls qos trust device cisco-phone".


Hope this helps.

Thanks for the responses. One more question for confirmation. I am being told one that auto qos supports enablement of the priority-queue when enabled on a switch interface. I always enable the priority queue manually. Can you confirm that enabling auto qos does or does not enable the priority queue on an interface. Its not in the interface configuration once auto-qos is configured for voip on the interface.

auto-qos is essentailly just a macro that populates other commands, if after applying auto qos you dont see priority queue out on the interface it's not there.
