I''m successfully using HTB + GRED to shape traffic based on the DSCP field. I would like to strip the DSCP and possibly replace it with normal ToS bits on egress traffic leaving my network. Leaving DSCP set is pointless, and could potentially cause problems with some ISPs that use DSCP internally I suppose. Setting ToS bits would seem ideal as most networks still honor it to varying

Hi, I would like to prioritize VOIP traffic when we use the phone, but other times not do traffic shaping at all. Right now I have my openwrt router set up with htb to do shaping. In order to get it to work well I had to set my upload and download speeds much lower than my line speed. With these settings, I get good VOIP reception even while surfing the net and doing a long download. However,

I ''ve been trynig for a long time now to make HTB and GRED to work togethen. The problem beeing that GRED doesn''t use handles (instead it uses DP:1 DP:2 etc) i can not preperly filter traffic to them. Tomas Graf suggested to use the tc_index index of u32 classifier so dear Sant .. i am currently with the following scripts that works! But when i try to add an HTB before the

As a necessety for my job is to real-time monitor the bytes, packets, packet dropped etc of all the qdiscs working inside the kernel i''ve tried varius methods: 1. Parse tc -s command output and update a round robin database and use rrdtool to graphically display tc statistics. [varius perl scripts exist for the above job] 2. Unsuccesfully tried QoS SNMP extensions, in order to use a

I am wondering whether the commands ''tc filter change'' and ''tc filter replace'' are working. Googling around revealed a few emails on the LARTC stating that unfoirtunately they do not work. A quick check showed that they are still not implemented (properly). Some propose a solution to build a second tree of filters and apply the 2nd one when a need for it

Hi, My HTB shaping is working perfectly, and i have setup a bridge and hosts behind the bridge are now getting only the bandwidth they are supposed to get. Thanks to every one here for helping me out :) Now I am thinking of making a graph of traffic going through various classes. Is their any thing readily available for it, or is parsing the output if tc and passing it to rrdtool the

Hi , I''m trying to call the tc_qdisc_modify function of tc in iproute2/tc. I could compile it with my stub program and got the executable. However, when i try to create an htb qdisc i get the following error : Unknown qdisc "htb", hence option "default" is unparsable However, if i use the tc tool, it works fine.. When I tried to understand the problem, it appeared to

Is there any library that i can hook on at runtime in order to create a qdisc dinamically from a program or if i want to do this I have to call the "tc" command? The disadvantage of calling the tc command from a process is that it creates an other process and this slows things up. Marius

I want to implement a snmp-agent to measure the bandwidth traffic per flow in a linux router. Is there any way to use tc in bash scripts in order to measure the bandwidth? In my first thought, the agent would fire repeatedly tc commands that would return the rate /flow. Is that speculation correct? Do you propose an alternative way to measure the bandwith through an agent. I found somewhere

Hi, I have a default class for my un-marked traffic (prio 5) and a prio 0 class for the important stuff, but I do not understand why my download traffic is duplicated in both. It work fine for my upload traffic (same setting except the red class but I have the same result if I create an esfq instead). Any comments/information will be appreciated. Below my config : tc commands from my scirpt :

Hello everybody, I am new to the lartc mailing list. I have been using "tc" for some time now. To be precise, tc & HTB to shape traffic. I did a lot of search on Google for 2 things: - A GUI to create configure new qdiscs & classes for HTB - A utility that will graph the data sent through all configured classes or qdiscs. I could not find anything. Could someone tell me if a

Hi all, this is really not really very easy to understand, or, to get in. Well, I''ve the following configuration on the router box: LAN - interface: eth0 - network: 192.168.2.5/24 - bandwidth: 100Mbit/s INET interface - interface: ppp0 - network: .dynamic.ip./0 - bandwidth: DOWN=1536kbit/s and UP=256kbit/s the LAN interface is to serve 6 other clients with internet and

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

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

Greetings all, I''ve been searching high and low for any inkling of how people are monitoring classes for long term usage data. I''m thinking something along a script to collect the data for mrtg or perhaps even an snmp module that would present them as interfaces to be polled....has anyone done any work in this area?

Hello, I am a newbie . I use a PC which have Windows OS . I want to monitor bandwidth , bytes, packets, packet dropped etc at several linux routers . I want to ask you some questions : Can I use round robin database and mrtg tool to generate html files at linux routers and call them from windows PC ? If it is impossible , can I use snmp to retrieve data from linux router at windows PC (snmp
