Configure a DiffServ IPv6 Class
You can add a new IPv6 DiffServ class name or rename or delete an existing class. The
screen also allows you to define the criteria to associate with a DiffServ class. As packets are
received, these DiffServ classes are used to prioritize packets. You can use multiple match

you can click the class link to display the Class screen.
