Differences between traffic policing and traffic shaping for S series switches

Traffic policing monitors the rate of traffic entering a network, and discards excess traffic to limit the traffic within a specified range and to protect network resources as well as user benefits.
Traffic shaping proactively adjusts the rate of outgoing traffic to reduce traffic bursts, so that outgoing traffic can be transmitted at a stable rate, preventing traffic congestion on downstream devices.
In most cases, traffic policing is applied to the inbound direction of a device, while traffic shaping is applied to the outbound direction of a device.
