Hello.
I'm running linux box with Slackware 9.1 and
compiled kernel 2.4.31 with "yes" to VLANs and "yes" to all QoS.
On this box i have more ethernet
interfaces:
eth0
eth1
eth2
and so as more vlan interfaces:
eth0.100
eth1.3
eth1.4
This is entrace(uplink) router to our whole network
and my goal is to shape users on this machine.
I want for this purpose use HTB so I write little
test script, which is shaping all users as default traffic and my computer as
unique class.
This script is olny for testing, if it all works
well, but I caught on some problems.
Here is my test script:
#!/bin/bash
#
/sbin/tc qdisc del dev eth0 root
/sbin/tc qdisc add dev eth0 root handle 1: htb r2q
1
/sbin/tc qdisc del dev eth1 root /sbin/tc qdisc add dev eth1 root handle 2: htb r2q 1 /sbin/tc qdisc del dev eth2 root /sbin/tc qdisc add dev eth2 root handle 3: htb r2q 1 /sbin/tc qdisc del dev eth0.100 root /sbin/tc qdisc add dev eth0.100 root handle 100: htb default 10 r2q 1 /sbin/tc qdisc del dev eth1.3 root /sbin/tc qdisc add dev eth1.3 root handle 13: htb r2q 1 /sbin/tc qdisc del dev eth1.4 root /sbin/tc qdisc add dev eth1.4 root handle 14: htb default 20 r2q 1 #classes for download

/sbin/tc qdisc add dev eth1.4 parent 14:5 handle 145 pfifo limit 10 /sbin/tc class add dev eth1.4 parent 14:4 classid 14:6 htb rate 3000kbit quantum 6000 /sbin/tc qdisc add dev eth1.4 parent 14:6 handle 146 pfifo limit 10 #my pc testing class

/sbin/tc class add dev eth0.100 parent 100:2 classid 100:2828 htb rate 1000kbit quantum 6000 /sbin/tc filter add dev eth0.100 parent 100: protocol ip prio 1 u32 match ip dst 217.67.28.28 classid 100:2828 /sbin/tc qdisc add dev eth0.100 parent 100:2828 handle 1002828 sfq perturb 10 #up /sbin/tc class add dev eth1.4 parent 14:5 classid 14:2828 htb rate 1000kbit quantum 6000 /sbin/tc filter add dev eth1.4 parent 14: protocol ip prio 1 u32 match ip src 217.67.28.28 classid 14:2828 /sbin/tc qdisc add dev eth1.4 parent 14:2828 handle 142828 sfq perturb 10 #default classes

/sbin/tc class add dev eth0.100 parent 100:1 classid 100:10 htb rate 3000kbit quantum 6000 /sbin/tc qdisc add dev eth0.100 parent 100:10 handle 10010 sfq perturb 10 #up /sbin/tc class add dev eth1.4 parent 14:4 classid 14:20 htb rate 3000kbit quantum 6000 /sbin/tc qdisc add dev eth1.4 parent 14:20 handle 1420 sfq perturb 10 As you can see traffic goes throught eth0.100 (this
is uplink interface to our ISP) and throught eth1.4 which belogns to interface
to one part of our network and where my testing PC is situated. Other interfaces
in this script are not used for now, this is due to simplify testing
purposes.
When I run this script I get no errors and
everything seems to be fine, but is not. My PC is served as default traffic and
not as uniqe class. When I'd removed default from root classes then all traffic,
including my PC was served as root class traffic.
Here is dump from

class, but why?
Anyone can help me or give som answers?
In forward to you, thanks a lot! :)
