Enabling Qos Globally; Configuring The Default Cos Value For The Switch; Reverting To The Default Switch Cos Value - Cisco WS-C2948G-GE-TX Configuration Manual

Chapter 14 Configuring QoS

Enabling QoS Globally

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

Configuring the Default CoS Value for the Switch

QoS assigns a CoS value to unclassified frames that are received on a port. The default CoS value is zero.
To set the default CoS value on the switch, perform this task in privileged mode:
Task
Step 1
Set the CoS value.
Step 2
Verify the CoS value.
This example shows how to set CoS equal to 7 in all unclassified frames that are 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 on the switch, perform this task in privileged mode:
Task
Step 1
Revert to the default CoS value.
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)
