With radius you can set the customer Queue by sending Rate-Limit.

According to the Mikrotik Manual, Rate limit only sets 4 items: "tx/rx speed", "Burst Limit tx/rx", "Burst Thresh tx/rx", "Burst Time"

However, In Queue I see 5 items: "Max Limit", "Limit At", "Burst Limit", "Burst Threshold", "Burst Time"

As far as I understand the fields map like this:

Radius Rate-Limit / Mikrotik Simple Queue
------------------------------------------------
tx/rx speed = Max Limit
tx/rx speed = Limit At
Burst Limit tx/rx = Burst Limit
Burst Threshold tx/rx = Burst Threshold
Burst Time = Burst Time

So every field maps 1 to 1 except for tx/rx speed. My Question is: Is there a way to control "Max Limit" and "Limit At" queue seperately? As far as I can see, they are always the same. What are the differences in the usage of these two fields?[/i]
