similar to: tc qdisc prio

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, 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

Hi, all I am interested in Linux related QoS, especially PRIO queue discipline (qdisc). I test some experiments about PRIO qdisc. Host A ------ Router A --- Router B --- Host C | 1Gbps | Host B ---------+ +-------- Host D flow 1 : Host A -> Host C (TCP) flow 2 : Host B -> Host D (UDP) priority 1 queue (pfifo, size 1000 packets ) : flow 1 priority 2

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

Hi fellows, i''m just a newbie to use the cool tc and played around the last 2 weeks. I''m quite confident - in theory - what''s possible and the basic difference between the queuing disciplines. We''re using a Fedora Core 3 box as Gateway (iptables,tc,iproute2 with NAT). Clients are coming in via eth1 and outgouing traffic (2Mbit/s SDSL) through eth0. So we

Hello Mailing list, I have a problem with the prio qdisc and I don´t know what is wrong in my configuration This ist a sample configuration and looks like this: #include "fields.tc" #include "ports.tc" #define X16(i) i i i i i i i i i i i i i i i i dev ppp0 { dsmark { prio(bands 6, priomap X16($be)) { class if ip_proto == IPPROTO_UDP;

Hello all, I might make a fool out of me, but I think the prio qdisc doesn''t work as advertised in any document I could lay my hands on. The following tests and observations were made with Linux kernel 2.6.20.21. This makes it up-to-date in the 2.6.20.x kernel family. My problem was that the link quality reported by the olsr.org olsrd degraded depending on the amount of payload

Hi, I have a router/firewall running Linux (like the most of you) and I wanted to do some traffic control. I''ve created an root PRIO qdisc like the example in paragraph 9.5.3.1 (http://www.lartc.org/howto/lartc.qdisc.classful.html#AEN903) with three SFQ child-classes. I wanted for interactive (ssh, telnet, ftp-control) and dns-traffic to be placed in the first queue, http should go in

Hi to all! I''m studying qdisc prio but I have some problems. I want to create 3 queue (3 bands prio), each one associated to a workstation. I mark (with iptables) packets using workstation mac address and then send all packets in a particular queue. qdisc prio with handle 10: (default priomap) WS1 -> queue 10:1 WS2 -> queue 10:2 WS3 -> queue 10:3 I set it correctly (with

Hi, Sorry to bother you all. I have a typical problem sharing DSL upstream bandwidth with users. I have 3 types of traffic high-priority, medium-priority and low priority. My upstream rate is 960kbits. Traffic (any priority) can vary in bandwidth from 0 to 960kbits. I have a test setup where I can pump 600kbit of high priority sustained and I have 400kbit of low priority traffic sustained. I

Hi, I''m trying to use prio qdisc with htb, however not the "usual" way (like for example FairNAT). Here is my idea: Root has HTB shaping traffic to link speed -> then goes PRIO queues -> each prio queue has HTB with sublasses for each user, should look like this: 1: htb qdisc | 1:1 htb class

Hi, I''m work on traffic shaping and I would like to know if it''s possible to mix differents Queueing Disciplines ?? I would like to combine the proporties of a PRIO discipline with that of a CBQ discipline. I read some documentation and I found nothing about that, can you help me ? I think to try something like that : tc qdisc add dev $DEV root handle 1: cbq … tc class add dev

Hi, I am attempting to set up some simple outbound shaping following the LARTC HOWTO. The HTB qdisc seems to work as the documentation says, but my filters don''t seem to be working. All of the packets go to the default queue regardless of what filters I set, it seems. (according to tc -s qdisc show) I am trying to get this working on my openwrt box (whiterussian rc6), but when

Hi, I am working on linux 2.6.16.I tried to prioritize traffic using prio module but its not working well.It always maps to same class irrespective of ToS.Is it possible to fix it using filters?Anybody fixed this problem? -- Regards Archana Rajagopal _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Dear Admins and Hackers, maybe i am to stupid to use ''tc''. But i having logical Problems to understand the Filter Rules in tc. Common Config: There is a Linux Engine (Debian) with a 2.6.11.11 Kernel which act as Packetshaper. Two Interfaces eth0 and eth1 are installed. Interface ''eth0'' is the Firewall Side Net 195.185.185.0/24. Interface

hello folks, this is my first post to that list. so I hope I am not completely OT here :-) reading the (excellent!) lartc and then writing my own qos-script I have still some open questions which I will try to formulate now: - "Now we can optionally attach queuing disciplines to the leaf classes. If none is specified the default is pfifo." - I can''t find info about Pfifo.

Hi! First, thanks for this great howto! Second, sorry for my english, it''s not the best! I have a question about the Linux qdisc. My configuation in short: Linux Box with 4 100Mbit ethernet inferfaces: - eth0 goes to a switch with ~60 PC''s connected wo use the internet connection. (192.168.1.200) - eth1 goes to an cable Modem with 5Mbit transfer speed - eth2 connects the 2.

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. Sorry for my poor english =) I have following config for traffic prioritization: tc qdisc add dev eth0 root handle 1: prio tc qdisc add dev eth0 parent 1:1 handle 10: tbf rate 7000kbit buffer 1600 latency 2msec tc qdisc add dev eth0 parent 1:2 handle 20: sfq tc qdisc add dev eth0 parent 1:3 handle 30: tbf rate 3000kbit buffer 1600 latency 50msec tc qdisc add dev eth1 root

Hi, I am attaching the patch for tc_class.c file in ./tc directory of iproute2 lastest version. This patch is to avoid segfault when listing classes. It happends only when using PRIO qdisc. I didn''t look why exactly it segfaults (guess becasue PRIO is classless), but this patch at least prevents it, so you can run the command and look what is happening to other classes. cd to iproute2
