4.1.1 Legacy shaper overview

The shaper functionality is used to control the output order of frames from each queue and the output order and output bandwidth for each port. The following figure shows the positioning of the shaper block described in this section.

As shown in the figure below, the legacy shaper consists of scheduling, which determines the queue from which the next frame will be sent, and port bandwidth control, which shapes the Ethernet interface bandwidth. This figure provides an overview of the legacy shaper.
