Hi,

Why traffic shaping done only at egress and not in ingress, whereas policing can be done on both ingress and egress ?

Thanks !

Shaping requires queuing in order to buffer excess traffic. Since queues are outbound by design then shaping can only be done outbound, whereas policing doesn't require a queue and it able to just drop excess traffic, so it can be used outbound or inbound.
