Limit Connections

HI.
I’m using the model : crs125-24g-1s-rm
Os Version : 6.39.2

I want to limit each interface by speed.
meaning port 2 for example, download and upload will be 15/15M

how can I do that?

as I see it’s only limit by ip.
like I want:
Interface 3 limit to 0.0.0.0/0 150KB/150KM

sorry for my questions.
I’m totally new at this Switch

Have a look at these instead: these queues are “global” linked to interfaces.
