[LARTC] CBQ and prio problem

[MR <max@cube.usr.dsi.unimi.it>]

Hi,
 I'm trying to configure a Linux machine to act as a "DS router" (ie it 
should manage differents priorities based on the TOS field) and as a traffic 
shaper too (let's say 800Kbit of 10Mbit). 
I've used the following commands but i wasn't able to shape the outgoing 
traffic (the prio works fine).

Thanks in advance for any idea,
 Max

#!/bin/sh

TC="/usr/sbin/stc"
DEVICE="eth0"
total="10Mbit"

$TC qdisc add dev $DEVICE root handle 1: cbq bandwidth $total avpkt 1000 \
cell 8

$TC class add dev $DEVICE parent 1:0 classid 1:1 cbq bandwidth $total \
    rate 800Kbit allot 1514 avpkt 1000 weight 80Kbit prio 8 maxburst 20 \
    mpu 64 bounded

$TC qdisc add dev $DEVICE parent 1:1 handle 100: prio bands 3 priomap 2 1 0

$TC qdisc add dev $DEVICE parent 100:1 tbf rate 10Mbit burst 10Mbit \
limit 10Mbit
$TC qdisc add dev $DEVICE parent 100:2 tbf rate 10Mbit burst 10Mbit \
limit 10Mbit
$TC qdisc add dev $DEVICE parent 100:3 tbf rate 10Mbit burst 10Mbit \
limit 10Mbit
