Yeah, duh, I'm dumb...
(no wonder I'm going for 3 more stars, so I can learn something)
What I did in my little qos world was use CS1/Scavenger as a place to put
stuff I wanted to drop anyway (like kazaa, bittorrent, etc)
So what is the recommended dscp for stuff you REALLY do want to drop, even
if there is NO congestion...
Thanks,
Joe

You would normally not drop scavenger class unless you are experiencing
congestion.

Can anyone tell me why Sungard (and I know several of you guys work for
them) would mark data from their websites with CS1 ???!?!?!?!?
What are you thinking? That is the scavenger class in many books and it's
frequently used in the real world to mark JUNK (to be dropped later).
Just today I solved an issue where a client couldn't get to a few big firm's
website. Turns out they are all hosted on Sungard.
I had to temporarily disabled the scavenger class's drop setting
policy-map somepolicy
class scavenger
drop
interface f0/0
service-policy output somepolicy
