Dear all, I copy a Ethloop script for tc script, but no response??? Does anyone know how to use ethloop? Ethloop; #1st parameter -- time in milliseconds from program start #2nd parameter -- operation to do #3rd parameter -- flow id #4th parameter -- operation dependent # #e.g 5000 R 2 4500000 #means at time 5sec set rate of flow 2 to 4.5MBps #Time should be in increasing time order #Each line is executed at its time and will change the ongoing traffic generators #example1 #Two flow simulation # Two flow simulation # lo will be used to TX and RX 0 i P 0x10010 lo 0 i P 0x10020 lo # set simulation packet size to 1k 0 S P 0x10010 1k 0 S P 0x10020 1k # start both flows 0 R P 0x10010 100k 0 R P 0x10020 100k # flow 1 to 50k and 10k later 2000 R P 0x10010 50k 4000 R P 0x10020 10k # finish at 6sec 6000 X 0 0 tc script: echo Clean all the tc setup ./tc qdisc del dev eth0 root echo Core router echo Create qdisc and set default to 1:30 ./tc qdisc add dev eth1 root handle 1: htb default 30 ./tc class add dev eth1 parent 1: classid 1:1 htb rate 1.5Mbit burst 50k echo Create class for EF ./tc class add dev eth1 parent 1:1 classid 1:10 htb rate 0.5Mbit ceil 0.5Mbit burst 50k prio 1 echo Create class for AF ./tc class add dev eth1 parent 1:2 classid 1:20 htb rate 0.5Mbit ceil 1Mbit burst 30K prio 1 echo Create class for BE ./tc class add dev eth1 parent 1:2 classid 1:30 htb rate 0.3Mbit ceil 1Mbit burst 30k prio 2 ./tc qdisc add dev eth1 parent 1:30 red limit 1800KB min 150KB max 450KB burst 200 avpkt 1000 bandwidth 1Mbit probability 0.4 echo Filter ./tc filter add dev eth1 parent 1: protocol ip prio 1 u32 match ip tos 0xb8 0xff classid 1:10 ./tc filter add dev eth1 parent 1: protocol ip prio 2 u32 match ip tos 0x0 0xff classid 1:20 ./tc filter add dev eth1 parent 1: protocol ip prio 3 u32 match ip tos 0x98 0xff classid 1:30 Thank you Patrick _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
