I have a MT box running 2.9.11. Currently I have pppoe users authenticating via RADIUS. I've added the Mikrotik Rate-Limit attribute to my dictionary. I've also added the rate-limit attribute to my pppoe user profile. In debug mode I can see the Rate-Limit attribute being sent. However, it appears the mikrotik box is ignoring the attribute. The /queue simple does not show any new queues. Any advice here?? Any walkthroughs or samples would be helpful. I've tried sending the value in a variety of formats, '256000/256000' and '256k/256k'.

Okay, I rework my radius server and now the attribute is succesfully passed to the Mikrotik box! A dynamic queue (Simple) is created when a user connects. However, the max-limit is always set to 0/0 instead of what I set it to '256k/256k'. Any ideas?

We are usign PPPoE and radius, and everything works fine with Rate-Limit. Users queue gets all parameters correctly. But, we also played with the Rate-Limit for some time before it worked as we want to. Be sure to correctly forward all the data Rate-Limit needs, and the most important, give them in correct order. It MUST work well

EDIT:
If you do not need burst, you can use Ascend-Data-Rate. It is simle to use, and it needs only one parameter. If you set, for example: Ascend-Data-Rate=262144 your user will get 256k up and down.
