3560 ____ Tried "auto qos voip trust" on a GIG interface after disabling QOS, there were no changes in regards to flowcontrol interface GigabitEthernet0/1 shutdown srr-queue bandwidth share 10 10 60 20 queue-set 2 priority-queue out mls qos trust cos auto qos voip trust So I am thinking that you do not need to turn off flowcontrol on 3560.
