Re: CAR

You can have a three level form of ratelimiting with normal rate, normal burst, then max burst. Best way to do the ratelimit would be to set the normal and max burst to the same, but follow the formula of:

(normal rate * 1.5)/8

So, if you wanted to rate limit somebody to 2Mbps in both directions, the config on the interface would look like this:

rate-limit input 2048000 384000 384000 conform-action transmit exceed-action drop

rate-limit output 2048000 384000 384000 conform-action transmit exceed-action drop

Hope this helps.

Re: CAR

The burst rate is the ammount of traffic that can be sent per second (this dictates the number of smaller burst per second to try and level traffic flow). Hope this helps.
