I''m trying to configure dsmark qdisc on 2.6.11.4 user mode linux and tc from iproute2-2.6.11-050314. I think I have some mismatch in my setup since adding dsmark qdisc fails *unless* I specify "set_tc_index" argument which I believe should be optional: # tc qdisc add dev eth1 handle 1:0 root dsmark indices 8 RTNETLINK answers: Invalid argument Mar 20 13:00:50 user user.debug

Hello all, Please could someone help me with this, I have been trying for days to get this to work. I would like to have BE, AF & EF classes with HTB qdisc. I can''t find any scripts online where this has been done. If I enable this filter: #tc filter add dev eth0 parent 2:0 protocol ip prio 1 \ #tcindex mask 0xf0 shift 4 pass_on then BE & AF classification seems to be fine but

Hi all! In short: Anybody wrote a patch for DSMARK to make it capable of marking only a ratio (a given arg to the tc command) of the packets it gets? Say, 20%? Or, do I have to hack into the source? Alternatives, like a filter spitting packets to 2 different DSMARK based on this ratio? In long: I''m a hungarian univ student involved in a project (RMD-QoS stuff) which needs

Hi, I am trying to get assured forwarding/expedited forwarding with gred and htb working. Below is the script I am using. The following steps are what I thing is how the script works. My problem is that if I remove the HTB qdisc from the script and have the GREDS parent as the dsmark it works, but when I add the htb as a parent of GRED and DSmark the parent of htb it does not work? Any

hi, I''m a beginner with qdiscs and other lartc stuff. After reading the howto and other related documents (i.e. some papers about linux and diffserv), I decided to start with some test. I found some example script to implement simple diffserv using dsmark, but, just after the first command: tc qdisc add dev eth1 handle 1:0 root dsmark indices 64 set_tc_index the system answered:

Hello! I have some trouble with dsmark qdisc. I''d like to set DSCP value of my outgoing packets and add a rate limit to each one. I learned HTB and dsmark. They work properly, but I can''t combine them like this: tc qdisc add DSMARK handle 1:0 ... tc class modify 1:1 ... tc class modify 2:2 ... ... tc qdsic add parent 1:1 HTB ... tc qdsic add parent 1:2 HTB ... ->

Hi folks I have created a script file (dsmark+policing.sh attached) to check graphic an text outputs of simutations, against original examples/dsmark+policing coding (see TCNG Reference Manual-pg.90). It uses tcng coding (*.tcsim file attached) and old tc coding (*.tcsim_old file attached) inserted in tcsim files. Observation 1: The graphic outputs from (*.tc included in *.tcsim) and (*.tc_old

I have a Gentoo Linux (kernel 2.6.11) server. Several months ago, I made a traffic shaping setup for my box (running a 2.4 kernel then) that worked beautifully. It gave high priority to SSH and RealAudio traffic, and put HTTP downloading traffic on a lower prio so they could only use what bandwidth was left. However, I''ve only just realized that tc is no longer accepting the commands I

Hello, I have the following proplem. My DiffServ configuration is working fine when I do ping, but when I use mgen the packets are not detected at the core router. Here is my core router configuration: #!/bin/bash tc qdisc add dev eth1 handle 1:0 root dsmark indices 64 set_tc_index tc filter add dev eth1 parent 1:0 protocol ip prio 1 tcindex mask 0xfc shift 2 tc qdisc add dev eth1 parent

Im using a Linux machine with standard pc hardware with 3 seperate PCI network interfaces to operate as a DiffServ core router using Linux traffic control. The machine is a P4 2.8ghz, 512mb RAM running fedora core 3 with the 2.6.12.3 kernel. All links and network interfaces are full duplex fast ethernet. IP forwarding is enabled in the kernel. All hosts on the network have their time sychronised

Dear all can anyone tell me how to mark packet''s DSCP value using tc? Thanks.

hi, i am currently working on a project on "design of diffserv testbed in linux". i am using tc utility of iproute2 for it. The qdisc dsmark used for marking the DS codepoint at the first hop router makes number of classes depending on the indices given in the command. But i am not clear how at the first hop router does scheduling takes place. what i mean is if i have two flows, whose

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;

Hi, I want to use the dsmark, but it always says: "unkown qdisc", although I have enabled it (y in Network options), and I have my kernel recompiled. I am using SuSE 8.1, 2.4.20 Kernel, tc available at the HTB site (with already precompiled HTB queue). Can anybody find the problem? thx _________________________________________________________________ MSN 8 helps eliminate e-mail

Hi all, Supposedly my router is itself streaming traffic to clients. Is it possible for it to mark its packets before going through dsmark?? I have gone through the examples in iproute2/examples, i noticed that there''s always an ingress and egress of which these are 2 different dev. Is it possible for before ingress and egress be the same dev?? I tried the script below but

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, I want to setup core routers to do both DSCP marking and to get the DSCP and forward packets based on DS field. I don''t want to separate DSCP marking to be done only at the edge routers. I know that dsmark is both used for DSCP marking and for getting the DSCP and forwarding packets according to DSCPs. In my case, since I want to do both of these I need two dsmarks.(?) I am not
