How to set the speed limit on Cisco router

In the Cisco router device, such as Cisco 2911 and 1941 router , only the support Cisco fast forwarding (CEF, CiscoExpressForward) of the switch or router can use rate-limit to flow, the specific settings at three steps:

Fast router limit inputoutput: This is the definition of data flow direction.

BPS: define the flow rate limit, the unit is BPS

Burst-normalburst-max: the definition of the data size, using 80001600032000 general, in bytes,when arriving data exceeds this capacity, will trigger an action, discarded or forwarding, so as to achieve the purpose of speed.

Conform-action and exceed-action: refers to the processing strategy following the rates and more than the rate of flow.
