Traffic policing


I have problem with setting rate limiting on port on NetIron CER 2024F. I want to set 40Mbps on port in both direction up/down. I try do this something like that:

NetIron CER 2024F(config-if-e1000-1/15)#rate-limit input 40000000 45000000


NetIron CER 2024F(config-if-e1000-1/15)#rate-limit output 40000000 45000000

and it works with average speed 38Mbps, but only in one direction (output). I also try with policy-map but switch behave similarly.

i can add that i set port speed manually by

NetIron CER 2024F(config-if-e1000-1/15)#speed-duplex 100-full  becasue my laptop's have fastethernet cards, maybe here is some problem.

bandwidth i measure  iperf 2.0.2

any suggestion or manuals how do this right?

Best regards,

Hi Info7,

     The config looks correct to me.  Please post a 'show ver' so we can see what version of code you are running on the CER2024F.

Setting speed-deplex should not effect the rate limiting.  What SFP optic are you using?

Thanks Michael.

Re: Traffic policing

Ok I am sure everything is correct,  and I have used that optic at 100mb in a CES switch.

Is it possible to test at a 1 gb? I think this is worth placing a tac ticket for a fix.

Re: Traffic policing

I'm facing the same problem on CER2024. Do you have any news about that?
