To delete an existing policy map, use the no policy-map policy-map-name global configuration
command. To delete an existing class, use the no class class-name policy-map configuration command.
To return to the default bandwidth, use the no bandwidth policy-map class configuration command.
This example shows how to create a class-level policy map called policy11 for three classes called prec1,
prec2, and prec3. In the policy for these classes, 30 percent of the available bandwidth is assigned to the
queue for the first class, 20 percent is assigned to the queue for the second class, and 10 percent is
assigned to the queue for the third class.

This example shows how to create a class-level policy map called policy11 for three classes called prec1,
prec2, and prec3. In the policy for these classes, 300 MBps of the available bandwidth is assigned to the
queue for the first class, 200 MBps is assigned to the queue for the second class, and 100 MBps is
assigned to the queue for the third class.
