Chapter 14 Configuring QoS

Enabling QoS Globally

To enable QoS globally on the switch, perform this task in privileged mode:
Task
Enable QoS on the switch.
This example shows how to enable QoS:
Console> (enable) set qos enable
QoS is enabled.
Console> (enable)

Configuring the Default CoS Value for the Switch

QoS assigns unclassified frames received on any port on the switch that the CoS value configured for the
switch. The default CoS value is zero.
To set the default CoS value, perform this task in privileged mode:
Task
Step 1
Set the CoS value for the switch.
Step 2
Verify the CoS value of the switch.
This example shows how to set CoS equal to 7 in all unclassified frames received on the switch and
verify the configuration:
Console> (enable) set qos defaultcos 7
qos defaultcos set to 7
Console> (enable)

Reverting to the Default Switch CoS Value

To revert to the default switch CoS value, perform this task in privileged mode:
Task
Step 1
Revert to the default CoS value for the switch.
Step 2
Verify that the default CoS value was restored.
This example shows how to revert to the default CoS value for port 8/1 and verify the configuration:
Console> (enable) clear qos defaultcos
qos defaultcos setting cleared.
Console> (enable)
