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

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

Hello all, I am having some trouble getting a firewall filter to work with TC. I am actually setting the mark via EBTables (which is working as far as I can tell, I am also logging the packet and my syslog reports lots of marks): ebtables -t broute -A BROUTING -p ipv4 -i eth1 -s 08:00:46:60:B3:57 -j mark --set-mark 7 --mark-target CONTINUE --log --log-level debug --log-prefix "EBFW Mark

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

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! 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 am using a server with asterisk and I am trying to prioritize voip traffick -- I am a newbie at this traffic shaping, so please bear with me. I used the script below and what happens is thatall traffic in the bulk class stops after a couple of minutes. Also, should I include the ports for rtp in the filter statements with the ports 5061 and 4569? Note I have a fairly big pipe -- supposed to

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 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

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

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 :

Hi all, I''m having some problems setting up qdiscs on a bridge.The config looks a little like this: ifconfig ifb0 up # Bring up the IFB for this bridge. tc qdisc add dev eth2 ingress tc qdisc add dev eth3 ingress tc qdisc add dev ifb0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8 # Raw qdiscs on each bridge port tc qdisc add dev eth2 root handle 1:0 cbq bandwidth

Dear members I''m new to this list and also new to tc command. I have a subnet with over 30 pc which have ip addresses from 172.16.1.1/16 range.I want that each computer in my subnet can work with internet with maximum 6k for download and maximum 6k for upload.when i run the following tc commands from my bridge the first pc works well but the second pc can not work with 6k and it has an

> does somebody have a working tc commandlist with bandwith limit for > internet>lan use? The following is a snippet that I got from my linux router vendor. I will be putting it in place this week. They ensure me that it will work. This takes an IP block that uses eth0 and limits the bw for that IP block to 3Mbit. I hope this is what you are after, as I am fairly new to this as well, I

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.
