     10Bug Description 
     11 
     12It is documented in HTB manual. The complaint was not displayed before and sharing was silently wrong. Quantum of leaf should be between 1500 and 60000 and it is computed as rate/r2q (or can be supplied independly). So that if your maximal leaf rate is 1Mbit (120000Bps) then r2q should be 3. If max rate is 10kbit (1200Bps) then r2q should be 1. It is warning only and will not affect functionality, only precision. devik

     14Smallest rate : 16kbit = 2 kilobyt / r2q (=10) = 200. And this is < 1500. So you get warnings. Biggest rate : 100mbit = 12.5 mbyte / r2q = 1.2 Mbyte > 60.000. So you get warnings.

     16If you do tc qdisc add dev eth0 root handle 1: htb default 10 r2q 1 Smallest rate : 16kbit = 2kilobyte / r2k = 2000. And this is > 1500. So no warnings. Biggest rate : 100mbit = 12.5 mbyte / r2q = 12.5 Mbyte > 60.000. So you get warnings. But you can overrule the quantum : tc class add dev eth0 parent 1:1 classid 1:11 htb rate 128kbit burst 2k quantum 60000

     18Quantum is used when 2 classes are getting more bandwidth then the rate. So it's only important for sharing the remaining bandwidth. In that case, each class may send quantum bytes.
