as I understand it, the 3850 has only one default queue for all traffic (which includes control traffic). So there is no default dscp to output queue mapping. To map DSCP values to a queue and actually create the queue, you need to define a class. The below will create two queues, one for the DSCP values you have specified, and one for the default class, which is all other traffic:
class-map DSCP_HIGH match dscp 32 48 54
policy-map DSCP_OUTPUT class DSCP_HIGH bandwidth percent 20 queue-buffers ratio 10 class class-default
there is a phrase "When no service-policy is applied, there are 2 default queues (queue 0 and queue 1). The queue-0 is used for control traffic (DSCP 32 or 48 or 56) and queue-1 is used for data traffic."
So at least 2 queues, thats why i wanted to see where other dscp will go. Or everything except 32,48,56 will go to second queue?
