You can use traffic shaping to determine the data transfer rate on the WAN Ethernet port. To set traffic shaping, use the traffic-shape rate command in the interface context. To disable traffic shaping, use the no form of the traffic-shape rate command. Traffic shaping works in tandem with the configured bandwidth. If you change the traffic shape rate, this automatically changes the bandwidth. Similarly, if you change the bandwidth, this automatically changes the traffic shape rate.
Note:
The traffic shape rate is determined in bits. The bandwidth is determined in kilobytes.
