Chapter 34      Configuring QoS
Configuring Standard QoS
Enabling QoS Globally
By default, QoS is disabled on the switch. 
Beginning in privileged EXEC mode, follow these steps to enable QoS. This procedure is required.
To disable QoS, use the no mls qos global configuration command.
Enabling VLAN-Based QoS on Physical Ports
By default, VLAN-based QoS is disabled on all physical switch ports. The switch applies QoS, including 
class maps and policy maps, only on a physical-port basis. In Cisco IOS Release 12.2(25)SE or later, 
yYou can enable VLAN-based QoS on a switch port. 
Beginning in privileged EXEC mode, follow these steps to enable VLAN-based QoS. This procedure is 
required on physical ports that are specified in the interface level of a hierarchical policy map on an SVI.
Use the no mls qos vlan-based interface configuration command to disable VLAN-based QoS on the 
physical port.
