after reading the new howto i wanted to rewrite my QoS-script, now that most parameters lost their mysteriousness. while rewriting i gave some classes new classid's which led to 'RTNETLINK answers: Invalid argument'. i decided to try the sample from the howto first, but got the same problem:
Sample configuration
This configuration limits webserver traffic to 5mbit and smtp traffic to 3 mbit, and limits the sum to 5mbit:
[...]
# tc class add dev eth0 parent 1:1 classid 10: cbq bandwidth 100Mbit \
rate 5Mbit weight 0.5Mbit prio 5 allot 1514 cell 8 maxburst 20 \
avpkt 1000 bounded
the above leads to an Invalid argument. it seems that tc doesnt like the classid 10: (at least the error disappears if i change it to e.g. 1:2).
have i done something wrong or is it an error in the example? this problem leads me also to the next question:
is the naming of classes essential for building them correctly? is parent 1:1 classid 10:0 somehow different from parent 1:1 classid 1:2? up to now i thought classid was only a name and the parent would be enough to make the classes' positions in the tree unambiguously...
regards,
Patrick

TC likes it just fine. It is the kernel that doesn't. This is my mistake, I
decided to spruce up the examples a bit without testing them afterwards.

Can you check if the CBQ example does work not?

Well, major numbers are a bit special in this respect. There is some stuff
going on with userspace per-socket specified PRIOs helping classify traffic,
the kernel does a lot of testing if you remain within your major number.
This is one of the completely never ever mentioned parts of CBQ which I hope
to bug people about.
Added you to the Thanks To list, thanks!

this was the cbq example :)
or do you mean besides this classid?

and i allready feared to get a RTFM as reply ;)

'does work now' I mean :-) I just improved it, please see if it helped.

We're not quite good enough yet that you can feel confident that everything
in the HOWTO is correct. So continue beating on it!

now everything from the cbq example executes without errors.
i can't tell you if it works the way it should since i'm
still learning to understand what it should do ;)

If we were to rework the naming, something like ...
1) parent 1: classid 1:2
2) parent 1:2 classid 1:2:5
3) parent 1:2:5 classid 1:2:5:8
... would make more sense.
The numbering scheme currently in place makes very little sense and is
quite wasteful of the number-space it uses (not that it matters much to
most people).
If the above were used, 'parent' would become quite unnecessary of course.
