Chapter 32 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. You 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.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
mls qos Enable QoS globally.
QoS runs with the default settings described in the “Default
Standard QoS Configuration” section on page 32-31, the
“Queueing and Scheduling on Ingress Queues” section on
page 32-15, and the “Queueing and Scheduling on Egress
Queues” section on page 32-17.
Step 3
end Return to privileged EXEC mode.
Step 4
show mls qos Verify your entries.
Step 5
copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Specify the physical port, and enter interface configuration
mode.
Step 3
mls qos vlan-based Enable VLAN-based QoS on the port.
Step 4
end Return to privileged EXEC mode.
Step 5
show mls qos interface interface-id Verify if VLAN-based QoS is enabled on the physical port.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
