Subject: [LARTC] Simple example of bandwidth management
Date: Fri, 22 Mar 2002 18:10:44 +0000	[thread overview]
Message-ID: <marc-lartc-101682051615224@msgid-missing> (raw)

Hi all,
I tried to configure a simple script like this:

*************************************************
#!/bin/bash

SORG\x10.0.0.33
DEST\x10.0.0.34

ipchains -F
ipchains -A output -s $SORG -d $DEST -j ACCEPT -m 1

tc qdisc del dev eth0 root handle 1:0 cbq bandwidth 33600bps avpkt 1000
tc qdisc add dev eth0 root handle 1:0 cbq bandwidth 33600bps avpkt 1000

tc class add dev eth0 parent 1:0 classid 1:1 cbq bandwidth 33600bps rate 
10000bps allot 1514 maxburst 20 avpkt 1000 prio 3

tc filter add dev eth0 protocol ip parent 1:0 prio 1 handle 1 fw classid 1:1
********************************************************

My problem is that I cannot see any bandwidth reduction, I download from 
10.0.0.33 to 10.0.0.34 with same speed as before (normal ethernet speed).
Maybe there exists some file under /proc fs to modify?

Some other debug info:

*******************************************************
[root@adsl bin]# tc -d qdisc show dev eth0
qdisc cbq 1: rate 33600bps cell 8b (bounded,isolated) prio no-transmit/8 
weight 33600bps allot 1514b
level 1 ewma 5 avpkt 1000b maxidle 928us

level 1 ewma 5 avpkt 1000b maxidle 928us
class cbq 1:1 parent 1: rate 10000bps cell 8b prio 3/3 weight 10000bps allot

[root@adsl bin]# tc filter show dev eth0
filter parent 1: protocol ip pref 1 fw
filter parent 1: protocol ip pref 1 fw handle 0x1 classid 1:1
***************************************************************

My system is:
RedHat 7.2 with kernel 2.4.7-10 on Intel Celeron 300MHz - 128 MB ram
Please let me know what I'm wronging...
Thank you for your great support.
Regards
Roberto Arcomano
