bandwith limiting on 3400cl switch

[benoo]

Hello

I have a 3400 cl switch behind an SDSL router with an 8Mb link. I would like to limit a portion of my network to use maximum 4Mb to go to internet.

On the doc I saw there is the rate limit operation possible on a particular port.

Do you think think this a good option for my goal ?

On this port I would connect another switch whit some end devices connected.

Thank you for you advice :)
