CBQ + 802.1Q VLAN
I need to shape traffic from some IP on one LAN, but I''m in trouble. There is a linux 2.4.26 connected to the Internet (eth0) / LAN(eth1) doing NAT. I''m using VLANs in the LAN Interface, that is connected to a 3Com SuperStack II in a 802.1Q tagged port.
I want to create a class that will limit the traffic at 384Kbit/s.

Clarification required for Prio in CBQ dequeing order
Hi,
I have been modifying the Wonder shaper to include another queue. My
understanding was packets would be de queued to hardware in the following
order:
cbq1 -> sfq10 > sfq20 > sfq30.
Also we only move onto the next queue when the preceding one is empty.
However is seems to be prio xx number that reflects the order packets are
de queued not to what flowid they belong to.

CBQ troubles, processor overload
Hey there everyone,
I appreciated everyone''s help so much in the last few posts I
decided to post some more! :)
We implemented our bandwidth management machine on the network
last week and everything looked great. After looking at it today,
anything past the machine is losing major packets and the latency is
high.
I''m using RedHat 9.0 on a Pentium 4 2.8ghz with 512mb of ram.

bandwidth limiting when src and dst are on the same interface
Hello!
I have a problem here.
I set up a Linux 2.4 machine to do bandwidth limiting for some of our
customers.
Current setup is something like this:

|Internet|225.1-----------225.10|limiter|228.1----228.10|cust. gw2|

CBQ and/or HTB help needed
Ok, this has been kicking my @$$ for weeks. I'm trying to get some
kind of bandwidth shaping working on my server. I need to throttle ftp
down so as not to suck up all the available bandwidth. I had cbq
working on the old server (an ancient RH 6.2 box) so I figured I'd just
move the config over and get cbq.init from sf.net and it should work.
Unfortunately it doesn't. At least

Wondershaper - question
Hi,
I have a question conercing wondershaper. I''m using the Clarkconnect linux
distribution for my linux router and I tried to use wondershaper.
On start up of wshaper, there are no errors or any other problems but I''m
not sure if it''s running correctly. Only one qdisc / one class is used and
when I start an uplink ftp transfer, my ping time is growing up to 1700ms -

how to emulate large IP routing table
Hi all
I am conducting the experiments comparing IP router forwarding delay and
MPLS LSR forwarding delay, it is obvious in theory MPLS in Core should be
faster than IP, but for small netork (only have several core routers),
result show it is not, this is why I want emulate a large IP routing table
in one core router.
can I do it and how ? right now I use static routing table (by using command

cbq ip range?
OK, finally I have made cbq run !
now I would like to know if it is posible to limit a range of IP to a speed.
something like this :
from 192.168.1.1 to 192.168.1.21 limit to 128K
I don''t whant to limit each IP to 128K, what I would like to do is limit all
20 IP to have a max of 128K.
Is it posible?

Bandwidth limiting a MASQed network.
Hi!
I just recently entered the wonderful world of the so called "advanced
routing" and decided to try and limit the bandwidth of a MASQed network
here and ended up in trouble :(.
The setup is (as far as I can tell) pretty straightforward. eth0 is
connected to the "real" network with a proper IP, and eth2 is 192.168.10.x
(the MASQed network). All of it is basicly right out of

CBQ throughput and efficiency question
Hello all, I am testing CBQ and HTB these days and I got a lots problem which needs your help. It is a little long text :) Thank you! (All my test is based on Redhat Linux9.0)

How to calculate HTB quantum
Hello all,
I have a question about the quantum parameter of a HTB class:
Is there a formula to calculate the quantum parameter of a class,
having the rate and ceil as parameters?
Sometimes, if I omit putting the quantum parameter for a class, I get
a message like "HTB: quantum of class ..... is big/small. Consider r2q
change" and shaping doesn''t work very smooth sometimes.

cbq parameters
If I create a cbq qdisc as a leaf of a cbq class, the bandwith rate is
the same of the root cbq qdisc or the rate of the cbq class?
Does exist the parameter rate on the "tc qdisc add" for cbq command?
tc qdisc add dev eth0 root handle 1:0 cbq bandwidth 10mbit avpkt 1000

tc class add dev eth0 parent 1:0 classid 1:3 cbq bandwidth 10mbit rate

Problen in cbq , fw
Hi,
In my LAN Iam trying to make following setup:
- All the traffic generated by 10.0.2.1 should go to 10.0.2.11,
If
the destination of this traffic is internet than it should be
placed on its interface eth1. Outgoing traffic on eth1 should be
shaped.For this I am using fw filters and cbq.
