Hi, I wanted to implement some QOS on my Linux Box with HTB, but after some time spend on the configuration and tests, I still don''t manage to have some correct results. Here are the details : -ROOT 2000 kbits -HIGHPRIO SUBCLASS 50 kbits prio 0 -SUBCLASS1 750 kbits prio 1 -SERVICE1 250 kbits prio 1

Hi, there is something I''m not able to understand about HTB statistics. Why the qdisc show show how many packets are overlimits but in the classes there are always 0 packets overlimits or dropped? I try to expain with a simple example. I create a qdisc htb with only a class and then i do a lot of traffic. pc-innocenti:~# tc qdisc add dev eth0 parent root handle 1: htb default 10 pc-innocenti:~# tc class add dev eth0 paren...
