How to Configure Standard QoS
Enabling QoS Globally
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.
This procedure is required on physical ports that are specified in the interface level of a hierarchical
policy map on an SVI.
Configuring Classification Using Port Trust States
These sections describe how to classify incoming traffic by using port trust states. Depending on your
network configuration, you must perform one or more of these tasks or one or more of the tasks in the
“Configuring a QoS Policy” section on page 38-36:
• Configuring the Trust State on Ports Within the QoS Domain, page 38-33
• Configuring the CoS Value for an Interface, page 38-33
• Configuring a Trusted Boundary to Ensure Port Security, page 38-34
• Enabling DSCP Transparency Mode, page 38-34
• Configuring the DSCP Trust State on a Port Bordering Another QoS Domain, page 38-35
