Re: How can I test my tc script?

Hi,

>$tc qdisc add dev eth0 root handle 1: htb r2q 1

You can add "default XX" to define direct class as 1:XX. Any traffic
that doesn't get classified by specific filters will end up in class
1:XX. If you wonder why XX is prefixed by "1:", it's because of the
qdisc handle.

The class you created here has classid of 1:1 and is attached to qdisc
itself.

>$tc class   add dev eth0 parent 1:100    classid 1:1 htb rate 256kbit
>ceil 256kbit prio 3

1) parent should be 1:1, that's classid of the class you created
earlier,
2) classid should be 1:100

that's probably what you wanted:
$tc class   add dev eth0 parent 1:1 classid 1:100 htb rate 256kbit
ceil 256kbit prio 3

>## Now I should create a filter for the ip address:
>$tc filter add dev eth0 parent 1:100 protocol ip u32 match ip dst
>172.16.100.1/32 classid 1:1

1) parent should be set to 1:1, that's the class you attach filter to
2) classid should be 1:100, that's the class, traffic should be
directed to

>## Now for the qdisc
>$tc qdisc add dev eth0 parent 1:100 handle 500: sfq perturb 2

that's ok
