Hello, all!

I noticed that RFC 2865 defined an attribute called "Class", but I don't know its meaning and usage. Can I use it as the QoS classfication for the user?

No. See your NAS documentation for how to configure QoS. The Class attribute is for something else. If you don't know how to use it, don't worry. You're not supposed to use it. It's intended for use in certain unusual situations. Alan DeKok.
