rate limit with no burst

[lkadlik]

Hi,

I am running IOS  c7200-p-mz.123-20.bin and want to hard set bandwidth on an interface to 10 MB. Is it possible to do to this using the rate-limit command? If so, how?  If not how can I achieve this?

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

rate-limit output 10000000 X X conform-action transmit exceed-action drop

What would the "X" values be if it is possible to use the above command?

Thanks

Yes, rate-limit (or a policier) could be one way to accomplish limiting bandwidth to a certain value, but without adjusting

For burst sizes, perhaps about half your bandwidth delay product.

hello,

your xxx represets burst traffic parameters.

If you limit traffic is to 10 Mbps, with a normal burst size of 1,500,000 bytes. Traffic that does not conform is dropped. You can create burst how much you want. Its just if user reach 10 Mb limit then he/she can use burst traffic in the congestion. If you do not want any bust to be configured then use normal exceed-action drop.

See the following command in the example:

rate-limit input 10000000 1500000 exceed-action drop

there is another way to do rate limit by using plicy map.

ip access-list extended ACL_SLAP
permit ip any any

class-map match-all CLASS_SLAP
  match access-group name ACL_SLAP

policy-map POLICY_SLAP
  class CLASS_SLAP
    police 10000000 100000 exceed-action drop

interface GigabitEthernet0/2
service-policy input POLICY_SLAP

hope this will help.

thanks
