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...

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 suggestion appreciated. thx jason 1. The DS field is marked by iptables in prerouting/mangle to the appropriate class. 2. DSMark masks the ds and copies ths dscp to the tcindex field. 3....

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 RTNETLIN...

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 _________________________...

Hi, There is some extra information in this email! I am working on implementing Diffserv on linux project. I am using suse 8.0 professional kernel 2.4.21. I have the following RPM:iproute2-2.4.7-697.rpm This supports a number of linux qdisc like cbq, htb among many others but it has no support for DSMARK, which I wish to use. Does anyone know of any patch that I could used or any other solution so that use of dsmark is possible. Traffic control using the other qdiscs is working fine! When I tried to implement the qdisc Dsmark, I got the message unknown qdisc: dsmark. I see that the solution for thi...

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 pare...

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 packets have been marked by different DSCP, then ho...

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

Hi all! Anyone got the same problem? If I: tc qdisc add dev eth0 handle 1:0 root dsmark indices 4 set_tc_index it works fine. If I: tc qdisc add dev eth0 handle 1:0 root dsmark indices 4 it says: RTNETLINK answers: Invalid argument I just don''t need that set_tc_index stuff for marking.

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: unknown qdisc "dsmark". Then I supposed that my kernel doesn''t have iproute2, but I can''t find it in my redhat 7.2 distribution. Furthermore...

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 clear with how to connect output of the outer dsmark (that does DSCP marking) to the inner dsmark that will get the DSCP an...

...thin the router has no DSCP set, but I want to set the DSCP values (based on a u32 filter) and THEN treat the packets just like the packets coming in from the LAN. - The problem is that the AFHTB script assumes the DSCP values are already set, but for locally generated traffic they are not. - As DSMARK is my root queue, I know I can "mark" the DSCP code just before handing the packet over to the egress interface using commands like ""tc class change dev eth1 classid 1:1 dsmark mask 0x3 value 0xb8"". But this marking is being done AFTER the AFHTB has done all its w...
