Traffic shaping restricts the rate and burst size of the flow which is transmitted out from the interface. The shaper is implemented by a token bucket. If the packet exceeds the maximum rate or the burst size, which means not enough tokens for the packet, the packet is stored in the buffer until there are enough tokens to transmit it.

Argument	Type	Description
port ( mandatory )	enum	Physical port for traffic shaper.
target	enum (queue0 | queue1 | queue2 | queue3 | queue4 | queue5 | queue6 | queue7 | wrr-group0 | wrr-group1 | port) { queue0:0, queue1:1, queue2:2, queue3:3, queue4:4, queue5:5, queue6:6, queue7:7, wrr-group0:8, wrr-group1:9, port:10 }	Three levels of shapers are supported on each port (including CPU port). port - entry applies to the port of the switch-chip. wrr-group0 or wrr-group1 - entry applies to one of the 2 Weighted Round Robin queue groups on the port. queue0-queue7 - entry applies to one of the 8 queues on the port.
meter-unit	enum (bit | packet) { bit:0, packet:1 }	Measuring units for traffic shaper rate.
rate	num	Maximum data rate limit.
burst	num	Maximum data rate which can be transmitted while the burst is allowed.
