[LARTC] I can not set up filters

[LARTC] I can not set up filters

[Gabriel Paues]

Hello!

I have set up a htb qdisc:
# tc qdisc show dev eth1
qdisc htb 1: r2q 10 default 12 direct_packets_stat 0

with the following classes attached to it

#tc class show dev eth1     
class htb 1:11 parent 1:1 prio 0 rate 80Kbit ceil 800Kbit burst 1575b
cburst 1969b 
class htb 1:1 root rate 800Kbit ceil 800Kbit burst 1969b cburst 1969b 
class htb 1:10 parent 1:1 prio 0 rate 240Kbit ceil 800Kbit burst 1772b
cburst 1969b 
class htb 1:12 parent 1:1 prio 0 rate 480Kbit ceil 800Kbit burst 1181b
cburst 1969b 

When I try to attach filters to it i get the following answer:
# tc filter add dev eth1 protocol ip parent 1:0 prio 1 u32 match ip
dport 80 0xffff flowid 1:10
RTNETLINK answers: Invalid argument

What am I doing wrong?

I Would really appreciate your help.

Regards,

Gabriel Paues

My guess:

You try to attach the filter to the class 1:0. Try attaching it to the
defined root class 1:1, or even better to the subclasses 1:10, 1:11 or 1:12
(think this is what you want).

(Foolish crap removed)

I mixed up flowid and parent, your syntax was correct, and I was wrong.
