Ibrahim, The traffic policing works under the "token bucket" principle. the number after the police 64000 is 8000 (burst normal) and there is also a (burst maximum) after that. the optional keywords of conform-action and exceed action are after that. I read the 8000 as the maximum burst per interval. As you said below which is 1/8th the poiced rate. -Greg

So, your example: SW2(config-pmap-c)#police 64000 8000 exceed-action drop You're only allowing for 64 Kbit/s and no more. The 8 Kbit/s is what you allow to be sent/received in a 1/8th of one second. That would mean if the configuration is changed to: SW2(config-pmap-c)#police 64000 16000 exceed-action drop You're still allowing for only 64 Kbit/s, but are you allowing for 16 Kbit/s to be sent/received in a 1/8th of one second (that's more than 64 Kbit/s)? Or are you only changing the time interval so only 4 Kbit can be sent/received in 1/16th of Regards /Yassir Ibrahim -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of kirsch Sent: den 18 april 2007 17:41 To: [email protected] Subject: Re: [OSL | CCIE_RS] CCIE_RS Digest, Vol 15, Issue 2 Ibrahim, For thew 3550 I think you can apply that under the class of a policy map. I used class default here. The policy maps are not the same as the routers. The default burst size I believe is 1/8th the police rate, but can be changed higher.

I'm a bit confused about policing in a 3550. As there is no rate-limit command under the interface configuration, I'll have to enable mls qos and configure a policy-map, no problem there. The confusing thing is that I have to configure the normal burst and there is no excess burst. So what is normal burst here? Does it have anything to do with Tc (time interval, 1/8 by default) or is it just how many extra Kbit have a chance to get thru if there is space? Thanks in advanced Regards Yassir Ibrahim -------------- next part -------------- An HTML attachment was scrubbed...
