LARTC - May 2005 - Change HTB "final qdisc" of the default walk-throught class

Hello everybody!

With a HTB qdisc:
# tc qdisc add dev eth0 root handle 99: htb

How can I change the "final qdisc" of the default walk-throught class?
# tc qdisc add dev eth0 parent 99:0 handle 88: sfq
results in: "RTNETLINK answers: Invalid argument"

CBQ automatically creates a xx:0 root class where I can attach final
qdiscs... - If there is a root class in htb, how is it named?


This is a check of my understanding. - I don''t need a solution of the
problem (e.g. with a leaf default class). - I need an answer to my
question and if it is not possible, the answer is: it''s not possible...
(-:


Thanks,

I think you can add a default class to your htb root-qdisc. As example

# tc qdisc add dev eth0 root handle 99: htb default 30
# tc class add dev eth0 parent 1:1 classid 1:10 htb rate 5mbit burst 15k
# tc class add dev eth0 parent 1:1 classid 1:20 htb rate 3mbit ceil 
6mbit burst 15k
# tc class add dev eth0 parent 1:1 classid 1:30 htb rate 1kbit ceil 
6mbit burst 15k

If the traffic isn''t matched by any filter it will get to 1:30
