These are the steps involved in the CBWFQ configuration process:

Step 1 Define traffic classes to specify the classification policy (class maps).

Step 2 Associate policies, or class characteristics, with each traffic class (policy map). A: CBWFQ with tail drop or

B: CBWFQ with WRED C: Optional: Default Class

Step 3 Attaching policies to interfaces (service policies).

This process determines how many types of packets are to be differentiated from one another.

To create a class map, use the class-map command to specify the name of the class map and enter class map configuration mode. You can use only one match command for each class map.
