[LARTC] flowid - classid ?

[christoph-kling]

root@Delta:~# tc filter add dev ppp0 parent 1:1 flowid 1:5 protocol ip
Unknown filter "flowid", hence option "1:5" is unparsable

root@Delta:~# tc filter add dev ppp0 parent 1:1 classid 1:5 protocol ip
Unknown filter "classid", hence option "1:5" is unparsable


I don't understand why it does not work. Can anybody explain me this problem?

You miss the filter you want to use.  See the manpages and the howto on 
www.lartc.org.

Christoph,

   it seems that you haven't created classes and queue disciplines. 
Classes are used to divide the available bandwidth of a device.  Queue 
disciplines are algorithms that decide which packet to send first in a 
given class.  Filters are used to identify which packets belong to a 
given class.

Regards,

Stephane.

Christoph,

   HTB is not a filter.  Examples of filters are : u32, fw, route, rsvp, 
etc.  HTB is a queue discipline :-)

   A filter is used to select desired trafic and put it in classes.

Stephane.
