Hi,

1.In the first configuration

If Total bandwidth goes above 10Mb and less than 11.8Mb, next rate-limit statement will be executed.If goes above 11.8Mb will get drop.

2.In the second configuration

All inbound HTTP traffic will not have a rate-limit.

All other traffic works same as the first configiuration.

3.If you want to limit the total B.W. to 10Mb

just enter as bellow.

interface f0

rate-limit input 10000000 1875000 1875000 conform-action transmit exceed-action drop
