When traffic needs to egress from an interface, it is put to an output queue.
When a traffic shaper is shaping egress traffic going out of an interface, it puts the traffic in an output queue also.
So can i say
- The only difference between having a shaper or not is just that the shaper controls how much traffic is allow to egress out of the queue/interface?
- If an interface outbound queue is full, it doesn't matter if a shaper is in place or not, tail packets will still be drop. - right?
