Hi guys, I have finally had the time to redo this. I hope it helps somebody, it's not gospel but should be close Basically it gives you the queue settings for Telstra Ethernet Access or MEF standard links when running on a Mikrotik and is required to ensure a link is not choked by backoff problems, the slower the link the worse they are..... I hope this comes through better this time, I tried to work out the formatting a bit but I'm sure you can work out which column is which L2 and L3 speed are Mbit/s, Limit-at, Max-Llimit and Burst are all Kbit/s L2 Speed L3 speed Limit-at Max-limit Burst Queue Type Queue Size Packets MTU Size 6 5.88 5880 5976 96 pfifo 8 1596 8 7.84 7840 7960 120 pfifo 9 1596 10 9.8 9800 9960 160 pfifo 13 1596 20 19.6 19600 19920 320 pfifo 25 1596 30 29.4 29400 29840 440 pfifo 34 1596 40 39.2 39200 39696 496 pfifo 39 1596 50 49 49000 49640 640 pfifo 50 1596 60 58.8 58800 59520 720 pfifo 56 1596 70 68.6 68600 69400 800 pfifo 63 1596 80 78.4 78400 79360 960 pfifo 75 1596 90 88.2 88200 89240 1040 pfifo 81 1596 100 98 98000 99400 1400 pfifo 110 1596 150 147 147000 148760 1760 pfifo 138 1596 200 196 196000 198080 2080 pfifo 163 1596 300 294 294000 298000 4000 pfifo 313 1596 400 392 392000 396800 4800 pfifo 376 1596 500 490 490000 496800 6800 pfifo 533 1596 600 588 588000 595200 7200 pfifo 564 1596 800 784 784000 792000 8000 pfifo 627 1596 1000 980 980000 988240 8240 pfifo 645 1596 Any suggestions, omissions or updates please share, this is just what I have developed over the last 30 or so links we have installed.
