I've searched, and I haven't found a firm answer as to Rate-Limit & Hotspot under 2.8.27. I've confirmed that the Rate-Limit attribute is being returned (both from watching the FreeRadius output and running radtest), but I don't see any queues created when a Hotspot user logs in.
I know that HotSpot is set up properly, because Ascend-Data-Rate & Ascend-Xmit-Rate both work properly and create the proper queues.
I've tried a number of variants of the format posted in the manual & in the forum, but nothing seems to create queues. Am I missing something, or does this just not work yet?
