hi
I want to know how do you set the burst on your pppoe profile for pppoe clients.If a client gets a 1Meg line and i only want him to get 1Meg burst how do you set it up and after 240sec it must go down to 256kbps for downlowding from a ftp site.Or can i set the pppoe profile for 64k upload and 1Meg download.What will be the best to control the clients bandwith
Thanks
I had simmilar problem 
and here is something I use (still testing my system) for PPPoE users :
ppp profile> print
…
1 name=“pppoe-profile” local-address=10.0.0.1 remote-address=pppoe-pool use-compression=default use-vj-compression=default
use-encryption=default only-one=yes change-tcp-mss=default rate-limit=48k/120k 78k/280k 48k/120k 45/45 5
…
If you are using Winbox to set up ppp profiles - put all of the “numbers” at RATE LIMIT field on Limits tab when adding/modifying ppp profile ((there is a explanation somewhere in the manualz)) 
hi
I have tryed thet a cople mounth ago and it does not work that way but if you have sucsses please let know.
I don’t think that burst for 240 sec is the real burst 
Bursts are nice for web-browsing, when user opens a web page, it longs 10s (probably 15-20 s), but not 4 minutes.
Burst allows him to open the page faster, while downloads are processed slower.
If you wish to set so long burst, burst calculation technique pretty well described here:

To accomplish second requested configuration,
ppp profile set profile_name rate-limit=256000/1024000
You are right, but, experimenting with numbers i came to this as a nice one… and, as manual sais, MT measures burst at time/16 interval !!!

Thank
Got the upload and download shorted out. Will have a look at that link you have posted on the forum
Thanks
ok Got the burst right on the burst by setting it up in the firewall under mangel and setting up in queues in global out.
Thanks for all the help.
