What is the difference between these when coloring traffic on an ingress port?
I'm under the assumption that AF sets individual queues up, and each one of those queues can have something done to it by a match statement.
I'm not clear on what the CS values are for. Maybe L2 CoS?
The DSCP value: When you use "set dscp ?", you'll get <0-some number>, all af values, ef, and all cs values.
I've noticed that if I mark with an AFxx, I get a chart when doing a show policy-map <name>, but if I just do a "set dscp 2", then that particular queue looks a little different under the show command.
