Hi,
I have a basic question on which I need help from you guys. My understanding is that when we configure policing instead of shaping, there is no queueing and scheduling in picture. These two are valid only when we configure shaping. Is my understand correct or missing anything?
Thanks,
Balajee

Hello Balajee,
policing does not buffer traffic, and so it cannot use SW queueing for managing them.
This means that in hierarchical QoS setups the parent policy is a shaper that invokes a child that is a scheduler.
However, Sw based queueing can still be associated to the physical interface even if policing is configured.
Hope to help

There's no additional queuing when using policing rather than shaping. Policing doesn't preclude queuing, it just doesn't contribute to it.
As there's no additional queuing when policing, there's also no scheduling (metering) out traffic from queues.
