Configuring a QoS Policy

Configuring a QoS policy typically requires the following tasks:
• Classifying traffic into classes
• Configuring policies applied to those traffic classes
• Attaching policies to ports
These sections describe how to classify, police, and mark traffic. Depending on your network configuration,
you must perform one or more of the modules in this section.

Classifying Traffic by Using ACLs

You can classify non-IP traffic by using Layer 2 MAC ACLs.
