similar to: Priomap

Hi list, I have a quick question about the priority mapping of tos bits. The manpage of tc-prio shows a nice table with tos bits and the band they are mapped to: TOS Bits Means Linux Priority Band ------------------------------------------------------------ 0x0 0 Normal Service 0 Best Effort 1 0x2 1 Minimize Monetary Cost 1 Filler

IMHO, the priomap explanation in the 9.2.1.1. of the LARTC HOWTO is not clear enough. I only understood it''s real behavior until I read this document from Russell Stuart: http://ace-host.stuart.id.au/russell/files/tc/doc/tc/priority.txt So, based in this information, I''ve prepared an alternative priomap explanation for this section of the HOWTO, if you like it as it is I could

Today I''ve noticed a bit strange (?) behaviour when prio qdisc is used. Example (having no filters/qdisc/etc. at the start) : Add simple 9 bands qdisc, set each mapping to lowest priority band: tc qdisc add dev $eth root handle 1: prio bands 9 priomap 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 If I do just that, all is fine - whole traffic ends in 9th band, what can easily be verified by tc -s

Hi to everybody. I read some info and documentation but i still can''t find how to make this simple setup for example . I just want to make priority of certain traffic without shaping the traffic . For example SSH and RDP first priority Mail second priority WEB and FTP third And everything else last priority. What will be the simple and best way to achieve this. I will appreciate

Dear list, before writeing this mail I really searched in the mailing list and deeply red the HOWTO, but I didn''t find a clear and univoque answer to my doubt. What is the meaning of the priomap? And what kind of TOS concerns? My first opinin was the one-to-one correspondence of the priomap and the 16 values of the four TOS bits. I mean priomap 1 2 0 3 0 0 0 0 0 0 0 0 0 0 0 1 implies

Hi all, First, let me say I''ve been most impressed with how quickly and professionally people on this list ask and answer questions. Next, let me say that with which I need help is properly configuring strict PQ, and gathering certain stats. Specifically: - I need to create a priority queue with four queues (let''s say they are of high, medium, normal, and low priority) - I

Hello, is it possible that the number of bands for the PRIO qdisc is limited to 16? tc qdisc add dev $DEVICE root handle 1: prio bands 16 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 succeeds but tc qdisc add dev $DEVICE root handle 1: prio bands 17 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 returns: ''RTNETLINK answers: Invalid argument'' Is there any possibility to raise the

Hello everybody, sorry for bothering you, but after some hours, I''m stuck. I''m living in a student''s foundation where I want to connect lots of people to a tiny DSL link. We have exactly four types of traffic. We want a really hard PRIO solution (as I promised to someone that group X will only use the link capacity which isn''t used by group Y). I could make a

hello to all i''m trying to set a filter but doesn''t want to work. i''ve set ut the qdiscs and the classes like this : tc qdisc add dev ppp0 root handle 1: htb default 20 tc class add dev ppp0 parent 1: classid 1:1 htb rate 120kbit tc class add dev ppp0 parent 1:1 classid 1:20 htb rate 30kbit ceil 120kbit tc class add dev ppp0 parent 1:1 classid 1:21 htb rate 30kbit ceil

This is my first attempt at understanding lartc: I want to throttle outgoing bandwidth fo a certain tcp port and leave other traffic the way it was. so I put a prio qdisc at the root of eth0 (dummy priomap since i want to use filters to switch bands): $ tc qdisc add dev eth0 root handle 1: prio bands 2 priomap 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 then attach a tbf qdisc at 1:2 : $ tc qdisc add dev

Hi, I have done this setup to give the machine 192.168.1.4 (masqueraded over dialup) the highest priority: #! /bin/bash WHAT="add" iptables -A PREROUTING -i eth0 -s 192.168.1.1 -t mangle -j MARK --set-mark 1 iptables -A PREROUTING -i eth0 -s 192.168.1.4 -t mangle -j MARK --set-mark 4 tc qdisc $WHAT dev ppp0 root handle 1: prio bands 3 priomap 0 1 2 tc qdisc $WHAT dev ppp0 parent 1:1

Hello, I''m still new in using tc...I wanna ask... 1. what is the difference between classless and classful qdisc?? when I made a qdisc, are I must create both of that qdisc...??? 2. what is the difference beetween three of the classless qdisc in linux redhat 2.4, sfq pfifo and tbf if I using the htb classful qdisc ??? because when I use htb classful qdisc it means I made a qdisc that

now, i''m learning and try to read a lot of article about tc command in linux for setting traffic shaper. but i''m doubt about In the theory about tc command ... In general, we define class under root qdisc but Is it can be possible ???? If we define another qdisc under root qdisc, Can i do it? because i have just read tc command syntax and i found this point ... syntax: tc qdisc

Hi, I am not sure if this problem has been discussed already. I am running red-hat LINUX 2.2.14 and the version of iproute that comes with it. The problem is that whatever I give as a command it tells me RTNETLINK answers : Invalid argument Example : tc qdisc add dev eth2 handle 10: root estimator 1sec 8sec prio bands 3 priomap 0 1 2 I have tried all kinds of combinations and it refuses to

OK - this is starting to get frustrating... Are there any known issues with 2.6.9 and traffic shaping? I am using 2.6.9 with geoip 20041115, and get odd oopses. The following script oopses my box: ----------------------------------------------------- #!/bin/sh -x IFOUT=''eth1'' IFIN=''eth0'' TC=''/sbin/tc''

Hi, I''m trying to set up 15 different delay intervals for packets leaving on an interface, using netems hanging off of a 16-band prio. I''m having trouble adding anything to bands higher than 10. Here''s what I tried: tc qdisc add dev eth0 root handle 1: prio bands 16 \ priomap 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 I want all default traffic to go to

Hello, I am trying to revive an old linux server installation, which still has libc5. Sadly, most current software does not compile anymore on this system, including the tc utility. As with other tools (net-tools, coreutils, procps etc.) I tried to compile and statically link (LDFLAGS=-static) on a more recent linux machine and copy the static binaries over to the old machine. But no luck

Hi, I have a server and ten clients in a Gigabit network. The server has 125mbps network bandwidth. I want that the server has 40Mbps bandwidth reserved for client 1 (IP 192.168.5.141), and the rest bandwidth is for all other clients. My script looks like this (I use IFB for incoming traffic): #!/bin/bash export TC="/sbin/tc" $TC qdisc add dev ifb0 root handle 1: htb default 30

Hi all, based on the information in the "Linux Advanced Routing & Traffic Control HOWTO", I was trying to set up traffic shaping on my firewall. While I found the HOWTO very useful, in the process I ran into some problems that I did not forsee: According to the HOWTO it seems that it should have worked, even after spending some time going through the sections looking for answers,
