Hi When I list all the qdisc with tc command it is not possible to see the parent of the qdisc. An example by the book. # tc qdisc add dev eth0 root handle 1: htb default 30 # tc class add dev eth0 parent 1: classid 1:1 htb rate 6mbit burst 15k # tc class add dev eth0 parent 1:1 classid 1:10 htb rate 5mbit burst 15k # tc class add dev eth0 parent 1:1 classid 1:20 htb rate 3mbit ceil 6mbit

Hi everyone, This is on a linux box, ingress (eth1) at 100Mb/s and egress (eth0) at 10Mb/s. The purpose is to test CBQ Here is my script ------------------------------------------------------------------- # Root qdisc tc qdisc add dev eth0 root handle 1:0 cbq bandwidth 9Mbit \ avpkt 1000 cell 8 # Classes tc class add dev eth0 parent 1:0 classid 1:1 cbq bandwidth 9Mbit \ rate 5Mbit weight

I''m trying to implement something similar the the diagram in section 9.5.2.1 in the LARTC HOWTO, but must have missed something somewhere :( I''m trying to hack up wondershaper, as it looked like a good place to start.. Here''s where I currently at, but I''ve tried alot of different things, all failing, some worse than others. The end result is to throttle back 126

I`m trying to shape both upload (eth0) and download(eth1). I made this script to acomplishthis but the filters are not working even though the classes and qdiscs are created. What am I doing wrong? #!/bin/bash tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1 htb default 10 r2q 5 tc qdisc del dev eth1 root tc qdisc add dev eth1 root handle 1 htb default 10 r2q 5 tc class add dev

Hello! I have an internet connection of 64kbps garanteed in a channel of 256kbps. On this connection the metropolitan speed is 10Mbps and in the provider''s network the speed is 100Mbps. I have a few clients behind my linux box and i want to set up some limitations because some of them are using it irrational. I am marking the packets with 0 for internet; 1 for metropolitan 2 for

Hi I have been playing with tc. I''m using htb and sfq. I tried to setup shaping of every ip address within a /20. I found that there must be an upper limit of about 2096 on the number of rules (classes, qdiscs or filters). I was testing a /20 which gives 4096 classes, qdiscs and filters. I''m using hashkey to optimize processing of frames. When executing the script below - it

Hi, I want work out a GUI interface for htb and now here comes to the part about adding and removing classes and filters. Here is an example script.

tc qdisc add dev eth0 root sfq perturb 10 I want to set perturb to 8 then i used this tc qdisc add dev eth0 root sfq perturb 8 system give me the following message RTNETLINK file exists I delete the rule by this :"tc qdisc del dev eth0 root sfq perturb 10" please tell me how can i delete the rule by another way and where is "RTNETLINK file"

Hi, Is it possible to attach another qdisq under a HFSC classfull ? I try it and the configuraton works : $TC qdisc add dev $dev root handle 1: hfsc default 30 $TC class add dev $dev parent 1: classid 1:1 hfsc sc rate ${RATE}mbit ul rate ${RATE}mbit $TC class add dev $dev parent 1:1 classid 1:10 hfsc rt umax 1500b dmax 30ms rate 200kbit $TC class add dev $dev

Hi, I'm looking into support for SS7 and I found an article (http://www.openss7.com/news13022002.html) which says that OpenSS7 supports Linux Support Inc's T400P-SS7 Quad T1 and E400P-SS7 Quad E1 PCI interface cards. It also says that Linux Support Inc is the primary sponsor of Asterisk. However I cannot find these cards on the Asterisk hardware page

Dear list, I have the problem that child classes don''t seem to issue the parent class to borrow from their parent. This is a simplified version of my script: tc qdisc del dev $DEV root tc qdisc add dev $DEV root handle 1: htb default 10 tc class add dev $DEV parent 1: classid 1:1 htb rate 10mbit tc class add dev $DEV parent 1:1 classid 1:10 htb rate 1kbit ceil 512kbit #groups tc

Hello, I use rrdtool to graph the traffic in the different classes on an interface, eth1. Basically, I use the output from tc -s qdisc ls dev eth1 my tc script (which is only for testing the graphing) looks like this: /sbin/tc qdisc add dev eth1 root handle 1: htb default 20 r2q 1 /sbin/tc class add dev eth1 parent 1: classid 1:1 htb rate 200kbit burst 15k /sbin/tc class add dev eth1 parent

Hi! I have a setup where I want to prefer traffic on one port (for testing purposes I used port 22) my setup is : tc qdisc add dev eth3 root handle 1: htb default 30 tc class add dev eth3 parent 1: classid 1:1 htb rate 96mbit burst 15k tc class add dev eth3 parent 1: classid 1:7 htb rate 2mbit burst 15k tc class add dev eth3 parent 1:1 classid 1:10 htb rate 96mbit burst 15k tc class add dev

Hi all I have a trouble configuring the qdiscs, when I indicate the "perturb 10" option to tc, i gives me this error: tc qdisc add dev eth0 parent 5:1323 handle 1323 sfq perturb 10 RTNETLINK answers: Invalid argument if I don''t put the "perturb 10" option, it works. another question is about iptables, when I indicate the " --set-mark" option: iptables -t

Help me  ... I try use the tc filter, but seems he doesn''t work, I already reconfigured my kernel ( 2.4.32 ) with all options related a QOS enabled ( like modules ) and nothing happens.

Hi, I´m shaping traffic using htb on both interfaces, I noticed that shaping download traffic is workinggreat but shaping upload traffic is not working at all (no sent packets, no dropped, no overlimits)I have eth0 facing the backbone and eth1 facing the LAN. Thanks for your help.These are the commands I run:tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1 htb default 10 r2q 5 tc

Hi, I''ve try to use htb to limit outgoing traffic but it seems that it doesn''t work. I guess the probem is the filter.
