[LARTC] HTB & Default Class

[<arisantois@unsoed.ac.id>]

HI All

I just tried HTB for about a week in my Intranet, first I implemented HTB
in My Network Cables and it run fine (It `s suprise how good it is compare
to cbq). Then I use HTB for our Wireless Network. But it just keep sent
packet to default class not to classid. I use kernel-2.4.7 default from
RedHat 7.2 distribution that I patch it with diff for 2.4.14. I use Orinoco
Silver as Wireless Card with wvlan_cs as driver and Precompiled TC from HTB
Wesbite. I assign virtual IP on my wireless eth1 192.168.30.1 and eth1:1
192.168.31.1.

I try to sharing my 512 Kbps bandwith to three faculties. Faculty A 128
Kbps ceil 512 Kbps (classid 1:10), faculty B 128 Kbps ceil 512 Kbps
(classid 1:20) and default goes to classid 1:30. But the HTB keep sending
packet to 1:30 class as default. I use HTB init from
http://freshmeat.net/redir/htb.init/21951/url_homepage/ . So any solutions
for me ?

[root@test root]# htb compile
tc qdisc del dev eth1 root
tc qdisc add dev eth1 root handle 1 htb default 30

tc class add dev eth1 parent 1: classid 1:2 htb rate 512Kbit burst 15k

tc class add dev eth1 parent 1:2 classid 1:10 htb rate 128Kbit ceil 512Kbit
burst 15k
tc qdisc add dev eth1 parent 1:10 handle 10 sfq perturb 10
tc filter add dev eth1 parent 1:0 protocol ip prio 100 u32 match ip dst
192.168.31.0/24 classid 1:10

tc class add dev eth1 parent 1:2 classid 1:20 htb rate 128Kbit ceil 512Kbit
burst 15k
tc qdisc add dev eth1 parent 1:20 handle 20 sfq perturb 10
tc filter add dev eth1 parent 1:0 protocol ip prio 100 u32 match ip dst
192.168.30.0/24 classid 1:20

tc class add dev eth1 parent 1:2 classid 1:30 htb rate 1Kbit ceil 512Kbit
burst 15k
tc qdisc add dev eth1 parent 1:30 handle 30 sfq perturb 10
