Configure DiffServ IPv6 Class Settings
You can add a new IPv6 DiffServ class name, or to rename or delete an existing class. You 
can also 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 criteria in a class.
