Hi Group

I am facing issue in usage of "rate limit" cli .
task says to limit ICMP traffic to 8 kbps.

i configured

access-li 101 per icmp any any
!
int f0/0
rate-limit in access-gr 101 8000 <bc> <be> conform-action transmit
exceed-action drop
!

Ques is how do i calculate bc and be in this case .
Normally ( from task that i have done ) ; I do following :

1/4 * 1/8 * rate desired

1/4 for tc value and 1/8 for bits byte conversion .
But this will not work here as 1/32*8000 = 250 and minimum Bc shd be 1000

Please throw some light on this ., Nothing else is mentioned in question .

Thnx in advance
