Hello.
Mikrotik CCR1036, fw 6.46.7. Approximately 400 PPPoE subscribers. Problem with speed limit for one subscriber of 400 Mbps and above. The incoming speed is accelerated to 700 Mbps, and the outgoing speed is limited to 300 and no more. I tried to change the queue type small to 50, 100, 1000 packets, sfq, 1 packet queue, pcq, disabled MRRU - it doesn't help. Changed the limit in the queue from the interface to the ip address - did not help. If you remove the queue, then the outgoing speed accelerates to 400, no more. There is no such problem with DHCP cleints. With a cisco, there is no such problem, but there is no way to change the mikrotik to a cisco. I also tried it on firmware 6.48.6 and on CCR1072. The cpu max load is about 30-40%. What do you advise?
