To disable auto-QoS on a port, use the "no auto qos voip" interface configuration command. Only the auto-QoS-generated interface configuration commands for this port are removed. If this is the last port on which auto-QoS is enabled and you enter the no auto qos voip command, auto-QoS is considered disabled even though the auto-QoS-generated global configuration commands remain (to avoid disrupting traffic on other ports affected by the global configuration). You can use the "no mls qos" global configuration command to disable the auto-QoS-generated global configuration commands.
