Catalyst 3850 QoS hardware queues

[apereira3]

Hello dears,

Do you know how many hardware queue the Catalyst 3850 performs? 

I found the information on the Cisco Catalyst 3850 Series datasheet:

●   Eight egress queues per port for wired traffic and four egress queues for wireless help enable differentiated management of different traffic types across the stack for wired traffic

There are many methods to software queuing handle packets, per example: PQ, WFQ, CBWFQ, LLQ; but I don't know if the "Eight egress queues per port" above is related with hardware queues.

Thank you for all"

Yes, they are hardware supported QoS queues.  (Much like the earlier 2960/3560/3750 had 4 hardware supported QoS egress queues, per port.)
