Chances are he just ran AutoQoS! To see which interfaces have AutoQoS enabled, use the show auto qos global command: 3750#show auto qos GigabitEthernet1/0/20 auto qos voip cisco-phone To disable AutoQoS on an interface, use the no auto qos voip interface command. To disable AutoQoS globally, use the no mls qos command. Beware that this disables all QoS on the switch. Chapter 19: Cataly
