The manual says (about prio): > Because it doesn''t actually shape, the same warning as for SFQ holds: > either use it only if your physical link is really full or wrap it > inside a classful qdisc that does shape. The latter holds for almost all > cable modems and DSL devices. I want to wrap prio inside of tbf. Here''s why: I have a server on a DSL line, which has

Hi I''m completely stuck with the tcng language - I assume there must be some way to arrange queues hierachically like eth1 | TBF | PRIO / \ class class but my attempt (below) produces a "inferno.tc:8: qdisc "tbf" has no classes near "prio"" when run through tcc. dev eth1 { egress { tbf (rate 128kbps, burst 64kb,

Hello, After reading the excellent HOWTO I got traffic shaping working nicely over ethernet devices on a test setup. I can''t put this setup live though, because our main firewall has three 2mbit hdlc interfaces instead of a single device. We are using multipath routing using iproute2 nexthop at the moment, and that works fine for firewalling. But now I have a need for shaping and

Hello all, This is a newbie question and it is very simple. In my local network of 10M bandwidth. I'd like to allow my PC to have a 9M bandwidth. While all the other PCs share the rest 1M bandwidth. Suppose my pc 192.168.3.2 gateway 192.168.3.1. Then, how could I set it in my gateway linux box? I think I should use tbf. Maybe, I need a cbq, but how to do it? The tc does not surport !

About the cbq.init. Four machines which traffic to limit in same LAN. Is the samething if I put limiting rules to four different files or all to the same file? Like: DEVICE=eth0,10Mbit,1Mbit RATE=64Kbit WEIGHT=6Kbit PRIO=5 RULE=192.168.0.5 RULE=192.168.0.6 RULE=192.168.0.7 RULE=192.168.0.8 OR four equal files with different IPs, Ids and no PARENT rule? What style of ID numbering you use if

Hello, I''am successful using a linux (2.4.20) bridge and the cbq.init_v0.7 script for traffic shaping. But I can only use the queuing discipline tbf (LEAF=tbf). If I try use queuing discipline sfq or none then tc applies the rules but no shaping occurs. Is this problem a normal behavior when using bridging ? I tried to use htb.init (using patched tc binary). It accepts the rules but

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

The limit parameter for SFQ qdiscs isn''t listed in the howto. Based on a mail from this list from 4 may 2002 ("SFQ queue lengths - generalization"), I''d guess it limits the number of packets/bytes in in the queue, but wether it does so by number of bytes, packets, or time spent in the queue I don''t know. Perhaps someone in the know could add a line to the

Hello everyone! I''m simply trying to put a PRIO inside an HTB (used to throttle). I''ve got interactive traffic on the network that I want to give priority (VoIP + Citrix + Video). I''ve used the filters in a CBQ script fine, but am having trouble adjusting them to this setup such that they properly assign the traffic. tc qdisc del root dev $e tc qdisc add dev $e

I tried installing the WonderShaper on my internal link, mostly to get the SFQ installed. I set uplink and downlink to 100000 to match the link speed and changed the bandwidth on the cbq line to 100mbit. This killed transfer speed *to* the box, knocking it from 30-40 Mbps down to about 800 kbps. Commenting out just the ingress control restored the speed. What about the ingress policer would do

Hi, The CBQ config file shud be some thing like this. DEVICE=eth0,10Mbit,1Mbit RATE=50Kbit WEIGHT=5Kbit Shall i hardcode the DEVICE BW as 10/100 Mbit or Shall i use any other tool like ethtool for getting this. ethtool gives Speed: 10Mbps If so, how about, if i use some other Interfaces other than eth0, like ppp0 or some other? C''d anybody can give a suggestion over this? thanks

I''m not a programmer per se (including C), but... I''d like to be able to give the define in sch_sfq.c (of, say, 2.4.20), SFS_DEPTH other values than 128 as an argument on the tc commandline. It could be powers of two up to 2^7 (128) as it seems that 128 is the current maximum. I''m a little anxious to ask the question "How do I do that?" ;-) Instead

Hi Stef, Reffering to page < http://www.docum.org/stef.coene/qos/faq/cache/7.html > I found a para as follows, " CBQ is not always as accurate as it should be. See docum.org on the test page for some tests with bounded classes. The algorithm used by cbq is very "link sensitive". It calculates the link idle time and for that it needs the real link bandwidth, average

Hello, Does anyone know when one should use cbq versus (simpler more accurate) htb? Specifically does cbq have added functionality that may be of interest to certain applications? from htb home> Both CBQ and HTB help you to control the use of the outbound bandwidth on a given link. Both allow you to use one physical link to simulate several slower links and to send different kinds of

Hi, I have some interesting problem with htb , I set up root class and sub-classess: $TC qdisc add dev eth0 root handle 1: htb $TC class add dev eth0 parent 1: classid 1:1 htb rate 1990kbit ceil 2000kbit $TC class add dev eth0 parent 1:1 classid 1:10 htb rate 190kbit ceil 200kbit $TC class add dev eth0 parent 1:1 classid 1:11 htb rate 1400kbit ceil 1600kbit $TC class add dev eth0 parent 1:1

If I create a cbq qdisc as a leaf of a cbq class, the bandwith rate is the same of the root cbq qdisc or the rate of the cbq class? Does exist the parameter rate on the "tc qdisc add" for cbq command? tc qdisc add dev eth0 root handle 1:0 cbq bandwidth 10mbit avpkt 1000 cell 8 tc class add dev eth0 parent 1:0 classid 1:3 cbq bandwidth 10mbit rate 50kbit allot 1514 cell 8

Hello there, Having made quite a lot of expensive mistakes i have finally clobbered together a script for the users on my network. Have a look at it and please suggest as to how can i limit bandwidth to each ip on this network to about 64Kbits.

Hi, I can''t get traffic shaping working. This is my situation: -------- ------ Net1 ----- |router| -------------------- | TC | ----------- Net2 -------- leased line ------ eth1 eth0 We use the leased line for normal traffic but also for synchronisation between 2 servers. The leased line is 2mbit. The synchronisation

Hi, I would like to know how to specify the token rate when a tbf qdic is created using tc tool.. Will it be a default value when tbf qdisc is created? This could be a silly question.... im quite new to all these stuff.. but im really interested.. any help will be most appreciated... thanks in advance, sanjeev -- ______________________________________________ Check out the latest SMS
