Unable to limit traffic on catalyst 3750 gigabit ports it has fiber modules,

I want to limit traffic 2mb per port

I have tried srr-queue and policier but it is not working and there is no ratelimit command under any interface,

Applying policy to output is not supported of the interface

policy-map rate-limit

police 2000000 8000 exceed-action drop

int gi1/0/3

service-policy input rate-limit

still when I start download it goes to 10 mbps

Hi Sayed,

few notations.

- output policing is not supported on this platform, that is a fact.

- the config you use seems correct

- is mls qos enabled?

- show policy-map interface is not supported and does not show any output

- use "sh mls qos int stat" to see if you have traffic out of profile.

- have you checked the stats of the interface the traffic is going to?

ie: user ----- gi1/0/3 3750 gi1/0/15 ---- network

If you check the counters (lower the load interval to 30 sec) on egress on Gi1/0/15 how much traffic do you see? (if you have other traffic try calculate the delta after you start the download).
