Could you please help me with configuration of MikroTik. I’m beginner at ISP and with MikroTik Router OS. So, I have got configuration:
- MikroTik Router OS v5.0
- PC x86, CPU 3800 Mhz, RAM 256 Mb
- ~300 PPPoE clients online
- 9 tariffs (1,2,3,4,5,6,7,8 Mbit/s,512Kbit/s)
I have configured mangles, queues. I don’t use “Simple queue”.
The same for other tariffs.
add action=mark-connection chain=forward disabled=no dst-address-list=\ PPPoE-1M new-connection-mark=PPPoE-1M-Download-Con passthrough=yes \ src-address-type="" add action=mark-packet chain=forward connection-mark=PPPoE-1M-Download-Con \ disabled=no new-packet-mark=PPPoE-1M-Download passthrough=no
Queue types (i chose PCQ and my rule like pcq-total-limit= (pcq-limit=40 packets) * (amount of online clients of tariffs 1Mbit):
The same for other tariffs, only pcq-rate and pcq-total-limit are different accordingly.
add kind=pcq name=PCQ-1M-Download pcq-burst-rate=0 pcq-burst-threshold=0 \ pcq-burst-time=10s pcq-classifier=dst-address pcq-dst-address-mask=32 \ pcq-dst-address6-mask=64 pcq-limit=40 pcq-rate=1024k \ pcq-src-address-mask=32 pcq-src-address6-mask=64 pcq-total-limit=2800
My problem is: when ~300 PPPoE clients online (~70 sub-streams for each tariffs 1,2,3 Mbit/s and some other sub-streams for other tariffs). ~800 queued packets for all queues. All clients have problems with opening web pages, ping, speedtest.net. It looks like very big delay.
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \ max-limit=0 name=PPPoE-1M-Download packet-mark=PPPoE-1M-Download parent=\ Download priority=2 queue=PCQ-1M-Download
Then I try Tools-Ping, choose IP address of PPPoE client and see error “105 no buffer space available”.
CPU load ~40%, RAM use ~50Mb.
If I turn off all queues, everything works well. Please tell me how to configure the queues? Probably, every client must has own queue, mangle. Or hardware is slow.
Thanks in advance!
