bust-size

Given that an explicit burst size value was not specified, the policer’s burst tolerance is set to the recommended value for a low-speed interface, which is ten times the interface’s MTU. For a high-speed interface, such as an OC-192, the recommended burst size is the transmit rate of the interface times 3–5 milliseconds.

Possible completions:

  <burst-size-limit>   Burst size limit (1500..100000000000 bytes)

低速鍊路上，使用10倍的的MTU

高速鍊路，如10G鍊路，則使用3-5倍的毫秒速率

OC192=10Gbps=10mbits/ms

3X10mbits per millisends=30mbits/ms，需要更改機關為bytes? ?=3750k
