Re: A QoS dscp question

Well, see, that's the thing. I read the RFC and it seemed a little
ambiguous. I have the CiscoPress ONT book, and it's adamant that AF4x
vs. AF1x is simply a class distinction. I always thought the same as you
that there was indeed a difference. Now, if you use the DSCP class
selector (CS1 - 7), then yes, those matter as they'd be processed by
non-DSCP compliant nodes.

I'd love to find a clear explanation of the AF classes. As I said, I
didn't come away from the RFC with a much better understanding. The
Cisco ONT book is the "clearest" one I've seen so far... :-)

Correct...I meant 3 drop probabilities and 4 classes!

Thanks for the links. I'll take a look at them for myself.
