Here''s the script. I would have posted it to a website, but I figure this''ll be better so it is always on the list for people in the future in case they wanted to see it. If you have any questions about any of it, please let me know. Mike and I aren''t the cleanest of programmers. Cron the script to run whenever you need it to. :) #!/usr/bin/perl # # TC Helper Script:

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. I want to create two leaf classes that limit the traffic at

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) 1.Is isolated of CBQ working? I have read Mr. stef word that he never made cbq isolated work. 2. I have setup an environment to test cbq: one tcp flow which I should protect and a noisy udp flow who will eat much of the

Hi i have configured my server with cbq and gred. The problem is that the cbq doesnt drop packets. The cbq is configured at a rate of 500Kbit "qdisc cbq 4: rate 500000bit (bounded,isolated) prio no-transmit Sent 100103048 bytes 73933 pkts (dropped 0, overlimits 0) borrowed 0 overactions 0 avgidle 24000 undertime 0 " The traffic that being generated is more than 5Mbit with the

Hi. I want to shape traffic from some IPs in my lan, but I''m w/ trouble. I have a linux box connected to the Internet. In the other side of this box is my LAN. I want to create the following scenario: My root qdisc is attached to a 100Mbit/s NIC I want to create a class attached to this qdisc that will limit the traffic at 384Kbit/s. I want to create two leaf classes that limits

Hey all, I had asked a question a little while ago about CPU usage being outrageous while using tc and a cbq qdisc. Ed was very kind and offered a few suggestions. One of these was to look at hashing. So after pounding away at it for about a week, I have a general understanding of how it works and have tried to implement it. Unfortunately, and quite obviously since I''m posting here, it

Hey everyone, I had a question about the class id''s using the TC command. I''m using a command that looks something like this: tc class add dev eth1 parent 10: classid 10:$variable cbq bandwidth 200Mbit rate 512Kbit allot 1514 prio 5 maxburst 20 avpkt 1000 bounded That''s just an example. My problem is I''m guessing the $variable is not allowed to be anything

hey guys i am regulating the traffic to & fro by my network through a linux gateway , its behaving strange. i regulated Downlink to 2Mbps & UPlLINK to 500Kbps. both perform well when those are done independent i.e. one at a time but when i do both from a client system ..the downlink however continues at 2mbps but the uplink falls down to 100kbps? is something wrong with my script or

Hi,All I am using iproute2 to manage bandwith for ADSL router.High,medium,low priority are needed for different protocol port on the ADSL's upstream side,as following: LAN --- |ADSL Router|------WAN When there aren't traffic on the specific priority, its bandwidth should be borrowed by other priorities.But it doesn't work.Here is my script: /usr/sbin/tc qdisc del dev nas0 root

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 cell 8 tc class add dev eth0 parent 1:0 classid 1:3 cbq bandwidth 10mbit rate 50kbit allot 1514 cell 8

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 :

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: |--------| backbone |-------| |---------| |Internet|225.1-----------225.10|limiter|228.1----228.10|cust. gw2| |--------| | eth0 |-------| eth1 |---------| | 225.20

all: I"m just trying to create a simple rsvp session to familiarize myself with the protocol. I don''t ever get a rsvp RESV message only PATH AND PATH TEAR messages. There is a timeout but i''m not sure whats causing it exactly. Can anyone shed some light on why? All the configs and output are below. Please let me know if you need more information. Thanks.

Hello all, I''ve got a couple redundant (Spanning Tree Protocol) boxes running FC1 minimal install + bridge-utils and they are working great for QoS + ntop monitoring. I''m wondering if I should handle the VoIP traffic a little differently. I don''t mind letting VoIP and Video lend out traffic when it isn''t being used, so that''s why I gave them such

Have a few generic questions about Kom-RSVP 1.) 11:00:05.175 WARNING: timer system overloaded, deviation is 30.080 sec - what timer is this referring to? System time? 2.) What is the relationship between the CBQ class created for RSVP traffic and the CBQ parameter that is in RSVP.conf? - ex. ### cbq qdisc ### tc qdisc add dev eth0 root handle 1: cbq bandwidth 10mbit avpkt 1000 mpu 64

Hi All, I found 2 unusual behavior with u32 classifier in Kernel 2.4.12. I’ve u32 compiled as module. 1> u32 filter seems not working if there is already some fw filter used for some other class. In order to get u32 working I’ve to delete root class, which in terms delete all fw filters too, and then same command for u32 works. fw is also compiled as module. 2> If I add u32 filter to my

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

I want to set the DSCP field of the incoming packets. And then put them in the correct queues. I can mark the packets: iptables -A OUTPUT -t mangle -d 10.10.10.12 -j MARK --set-mark 1 tc qdisc add dev eth0 handle 1:0 dsmark indices 64 set_tc_index tc class change dev eth0 classid 1:1 dsmark mask 0x3 value 0xb8 tc filter add dev eth0 parent 1:1 protocol ip prio 1 handle 1 fw

Hi all, I''m sure I''m soing something wrong here. I am trying to set up a rate limit inside another rate limit. eg. I have a 512K rate limit on a particular VLAN. I am using an IFB so that packets passing through the bridge are counted at each port.(ie the throughput is limited to 512K, not just the traffic in one direction.) This part works OK, but I also want to limit a

Hi all, I have installed 2.4.5 kernel, Debian Potato. my tc script: #!/bin/bash tc qdisc add dev eth1 root handle 20: cbq bandwidth 10Mbit avpkt 1000 echo root tc class add dev eth1 parent 20:0 classid 20:1 cbq bandwidth 10Mbit rate \ 10Mbit allot 1514 weight 1Mbit prio 8 maxburst 20 avpkt 1000 echo class tc class add dev eth1 parent 20:1 classid 20:100 cbq bandwidth 10Mbit rate \ 5Mbit allot
