QoS and CLASSIFY

Linux Advanced Routing and Traffic Control

Hi Guys

After googling a little I couldn't find the correct answer..

When I use :
tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip dst
192.168.0.11 flowid 1:30 , I can shape traffic to 1:30.( works like a
charm)

Now instead tc filter I would like to use CLASSIFY as below:

iptables -t mangle -A POSTROUTING -o eth0 -d 192.168.0.5 -j CLASSIFY
--set-class 1:30

but when I comment tc filter and include iptables -t mangle..CLASSIFY
nothing works.

Where Am I wrong??


Scenario:

#!/bin/bash
#
#        128Kbps              192.168.0.1
#       <-----  eth1 firewall   eth0
# internet-adsl-----+squid---------------4 desktops
#       ----->      +QoS                   192.168.0.5
#       450Kbps                                     .11
#                                                   .12
#                                                   .20
#
modprobe sch_htb sch_prio sch_sfq cls_u32
tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1:0 htb

tc class add dev eth0 parent 1:0 classid 1:1 htb rate 450kbit ceil
450kbit

tc class add dev eth0 parent 1:1 classid 1:30 htb rate  80kbit ceil
400kbit
tc class add dev eth0 parent 1:1 classid 1:40 htb rate  80kbit ceil
400kbit
tc class add dev eth0 parent 1:1 classid 1:50 htb rate  80kbit ceil
400kbit
tc class add dev eth0 parent 1:1 classid 1:60 htb rate  80kbit ceil
400kbit

tc qdisc add dev eth0 parent 1:30 handle 30: sfq perturb 10
tc qdisc add dev eth0 parent 1:40 handle 40: sfq perturb 10
tc qdisc add dev eth0 parent 1:50 handle 50: sfq perturb 10
tc qdisc add dev eth0 parent 1:60 handle 60: sfq perturb 10


thanks in advanced
