Kurt,
what do you have the burst allocations set to?
If you only want this customer to have 1500kbs period. You will need to
set the allocations much smaller or set to 0

Sorry to answer a question with a question, but are you measuring
at the SM, or at some upstream router?
The reason I ask, is I have seen some CDN traffic that does not
seem to follow traditional TCP congestion control. It will send
at twice the rate limit, causing 50% packet loss to its own
traffic and everything else to that same subscriber. Evidently
some TCP geniuses have decided to use latency rather than packet
loss as the indicator of congestion, and that the objective is
goodput not throughput. Works for last mile technologies like T1
and DSL with big buffers at the head end of the fixed speed serial
connection, not so good with the type of rate limit queues we tend
to use unless we can provision the queues with big buffers.
Probably not your problem, but I thought I’d bring it up just in case.

*Subject:* [AFMUG] 450SM sustain bucket throttle not working..
I have a 450 SM that is rate limited in the SM to 1500kbps
download on the sustain side. I noticed last night that this
customer was pulling a steady almost 3mbps download for several
hours on end. How is this possible? Is there a problem with 13.2
firmware? Its a 3.65ghz SM.
see attached.
