2. QoS Flow Chart

The following flowchart displays the various steps required in setting up a QoS policy. You basically now need to create a Classifier with each Classifier made up of one IP Classifier Element, or one L2 Classifier Element or one IP and one L2 Classifier Element. You then add the Classifier to a separate Policy on a per port basis. Or you can group a number of Classifiers into a Classifier Block and then add the Classifier Block to a Policy on a per port basis. The Ethernet Routing Switch 5500 supports up to 114 Classifiers per port for a total of greater than 40K Classifiers in a fully configured stack.
