I'm trying to build a QoS system that would divide the outgoing traffic
into four categories, each one also subdivided into two more categories.
For that I chose a htb root qdisc subdivided into four classes, each of
these classes contains also a htb qdisc. Until these point everything
goes well, but when I try to attach a new class to the leaf htb qdisc a
problem with the sintaxis arises. Code follows:
tc qdisc add dev $DEV root handle 1: htb default 30
Remember if $DEV is eth arp will go here.
tc class add dev $DEV parent 1: classid 1:1 htb rate
${UPLINK}kbit
tc class add dev $DEV parent 1:1 classid 1:10 htb rate
${UPLINK}kbit
tc class add dev $DEV parent 1:1 classid 1:20 htb rate
${UPLINK}kbit
tc class add dev $DEV parent 1:1 classid 1:30 htb rate
${UPLINK}kbit
tc class add dev $DEV parent 1:1 classid 1:40 htb rate
${UPLINK}kbit
If you want UPLNK to be the max then children need UPLINK/4 - the parent
will not cap it. Use ceil UPLINK aswell if you want each to be able to
reach max when other classes are empty.
tc qdisc add dev $DEV parent 1:10 handle 10: htb default 12
This is strange, not sure if it's what you want - you don't need another
htb here, though it is possible it's not normal. If you just want a
child under 1:10 then do as you do below with parent 1:10, but remember
parents don't cap rate of children.
tc class add dev $DEV parent 10: classid 1:11 htb rate
${UPLINK}kbit
prio 1
If you really want htb under htb then classid 10:11 may work.

tc qdisc add dev $DEV parent 1:11 handle 11: sfq perturb 10
tc qdisc add dev $DEV parent 1:12 handle 12: sfq perturb 10
...
If I attach the classes to 1: instead of 10: everything goes well, but I
do not understand why I can't attach a class to 10:
Any help would be appreciated.
