Normal and Extended Burst values for rate-limit command

Hi,

What is the guideline for determining the normal and extended burst values used in rate-limit commands? Some documents say that

normal burst value = (bps/8)*1.5

exd.burst value =2 * normal burst value

For example supposing that I'm trying to limit rate of the traffic incoming on an ethernet interface to 512Kbps, what values should I use?

Regards.

Re: Normal and Extended Burst values for rate-limit command

This is the formula that Cisco recommends. For 512 Kbps, you would have to use the command ' rate-limit input 512000 96000 192000 conform-action transmit exceed-action drop' .
