Diffserv Class Summary

Use the Diffserv Class Summary page to create or remove DiffServ classes and to view summary information about the classes that exist on the device. Creating a class is the first step in using DiffServ to provide QoS (Quality of Service). After a class is created, you can define the match criteria for the class.

To access this page, click QoS > Diffserv > Class Summary in the navigation menu.

Use the buttons to perform the following tasks:

To add a DiffServ class, click Add.
To change the name of an existing class, select the entry to modify and click Rename.
To remove one or more configured classes, select each entry to delete and click Remove. You must confirm the action before the entry is deleted.
