CEF and CAR

Okay... The docs say that CEF is required to use CAR. However when I turn CEF off it looks from 'show int eth0/0 rate' like rate-limit is catching more exceeded packets. This is rather confusing. If CEF is enabled doesn't that cause the router to fast swich more packets?

Re: CEF and CAR

Just wondering if applying the rate-limit in input or output direction of an interface will make any difference in how policing works along with switching.

I have he rate-limit set the same in both directions, but I still see the vast majority of traffic fast switching.
