Hello,
I've just recently started to use IMQ and I got puzzled after seeing the imq usage example on the linuximq.net site:
It was something like this:
tc qdisc add dev imq0 handle 1: root htb default 1
tc class add dev imq0 parent 1: classid 1:1 htb rate 1mbit
tc qdisc add dev imq0 parent 1:1 handle 10: htb default 5
tc class add dev imq0 parent 10: classid 10:1 htb rate 256kbit burst 30k prio 1
and I tried the following (like in the classic htb examples from lartc) and it worked:
tc qdisc add dev imq0 handle 1: root htb default 99 tc class add dev imq0 parent 1: classid 1:1 htb rate 1mbit tc class add dev imq0 parent 1:1 classid 1:10 htb rate 100kbit tc class add dev imq0 parent 1:1 classid 1:99 htb rate 900kbit
tc qdisc add dev imq0 parent 1:10 handle 100 sfq perturb 10 tc qdiisc add dev imq0 parent 1:99 handle 9 sfq perturb 10
Can someone help me understand the first example and why would someone create a root qdisc that redirects all traffic to a class and then instead of attaching child classes to that class, one would create a qdisc associated with that class and then attach the child classes to it.
