The use of the 'Class' attribute is site specific; you can use it to carry any value you want. If you're setting client QoS settings dynamically then the attribute is User-Priority-Table as described in RFC 4674.

Personally I think the best way to use the Class attribute is to link Authentication and Accounting sessions. All other session attributes can be stored in a database.
