PCQ Queues Question

Tue Oct 22, 2013 7:55 pm

Hi

I have bought CCR1036-12G-4S and use it like pppoe server for my internet clients.
I work with FreeRadius and I use address lists.
I have a problem with PCQ queues:
Example:
name="SC_Download" kind=pcq pcq-rate=80M pcq-limit=50
pcq-classifier=dst-address pcq-total-limit=15000 pcq-burst-rate=0
pcq-burst-threshold=0 pcq-burst-time=10s pcq-src-address-mask=32
pcq-dst-address-mask=32 pcq-src-address6-mask=64
pcq-dst-address6-mask=64

Evereting work fine when there is just a little users.
If I have > 100 PCQ queues then the routerbord start droping packets although there is Avg. Rate < pcq-rate and per user speed become about 1-2 Mbit. There is a lot of traffic available.
Where is the problem. I dont understand.
