● SoftMin: Minimum shared buffer given to the port. By default, a small piece from the shared buffer will be allocated to a non-priority queue to ensure that it can transmit traffic. It can be removed by configuration.
● Soft Start: The shared buffer is constantly monitored for utilization. If the total buffer utilization reached 75%, the dynamically allocated portions of buffer units per port queue will start to reduce. The higher the shared buffer utilization, the more aggressive the reduction of the buffer units.

● Soft End: Occurs when the shared buffer is fully utilized and cannot provide additional buffers to port queues to absorb micro-bursts (SoftMin and SoftMax are equal). The shared buffer will still provide a SoftMin buffer unit per port queue to ensure that these queues have minimum buffer to transmit, but nothing additional.
