What problems are you seeing? The following page should give you the required commands

Also the following FAQ should help

Re: rate-limiting in 2948g l3

Router(config-if)# rate-limit input {32000-100000000} {0-64000} if i enter this command its saying incomplete command.

I have entered the following command:

Router(config-if)#rate-limit input 100000 8000 8000 conform-action transmit exceed-action drop

where 100000 is the bits to be limited

8000- burst size in bytes

If i enter the above command the command gets accecpted but the data transfer is not getting limited.

can u help me?

Re: rate-limiting in 2948g l3

I think you need to change the port from L2 to L3.

You would need the interface command 'no switchport mode access' to remove the L2 aspect. And, add an IP address for the L3 segment. Then use the rate-limit command.

Caution on the rate-limit command since the first number is the bandwidth limit in bits per second. The second and final figures are in bytes.

Sample: A 6 Meg rate-limit will have 6000000 as the first, 750000 as the last two numbers.
