Configuring Classification
Classifying network traffic allows you to organize packets into traffic classes based on whether the
traffic matches specific criteria. Classifying network traffic is the foundation for enabling many QoS
features on your network.
This section contains the following topics:
• Creating a Class Map for Classifying Network Traffic, page 24-34
• Creating a Policy Map for Applying a QoS Feature to Network Traffic, page 24-35
• Attaching the Policy Map to an Interface, page 24-36
Creating a Class Map for Classifying Network Traffic
Class maps allow you to define classes of network traffic in order to apply QoS features to each class.
Complete the following steps to create a class map:
Step 1 Enter enable mode.
