You would enter these commands to match classes to the four simple AF
PHBs:
ProCurve(config)# qos map Class 11
ProCurve(config-qos-map)# match dscp 10
ProCurve(config)# qos map Class 12
ProCurve(config-qos-map)# match dscp 18
ProCurve(config)# qos map Class 13
ProCurve(config-qos-map)# match dscp 26
ProCurve(config)# qos map Class 14
ProCurve(config-qos-map)# match dscp 34
This example only shows how to define what traffic is placed in the class.
When actually configuring CBWFQ, you would set the bandwidth for the class
at the same time. See "Allocating Bandwidth to a Class" on page 7-26.
Classifying Traffic According to IP Header Fields. You can classify
packets according to the fields in their IP headers—that is, according to their
source and destination IP addresses, port number, and protocol. This method
of classifying traffic mimics simple WFQ. However, you can place traffic to
and from an entire range of addresses in the same class. One of the
shortcomings of WFQ is that the more subqueues an interface supports, the
