Thanks for your response, my apology for not very clear.
This is what I visualize:
Egress traffic from fabric-> -------q1---scheduler---|
| To FIFO queue of the port--->Port shaper/Port policer--> WIRE
Egress traffic from fabric-> --------q2 -scheduler---|
Above traffic bound for egress port are received into egress queues from the fabric, schedulers pick up the packet from the queue and place it on the FIFO queue of the port.
So when we use Port based shaper or interface specific stateless filter, are we applying at the position shown above i.e
these port based policers/shaper are applied post classification and scheduling and right before the traffic is put on the wire?
I know Filter based egress policer acts on the traffic as it about to enter egress queues from the fabric. Note that this filter is applied before queueing and scheduling but I am not sure about Port based shaper and interface specific policer.
