Hello Stef, I am working on a Bandwidth management project as part of my college curriculum.I am running TCNG 10-b but I am not able to classify packets based on MAC address using tcng, so I am running tc commands in /tcng/bin and they are working. But is there a way out to classify packets based on MAC address using TCNG. And, I am successful in throttling down the Bandwidth to 8kbit using HTB. Below that I get report to change r2q. I want to bring down the Leaf class Bandwidth to 3kbit.My script is as below: Tc Script to throttle down the Bandwidth to 8kbit based on MAC address and IP address tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1:0 htb default 30 r2q 1 tc class add dev eth0 parent 1:0 classid 1:1 htb rate 24kbit ceil 24kbit quantum 1514 tc class add dev eth0 parent 1:1 classid 1:10 htb rate 8kbit ceil 8kbit tc qdisc add dev eth0 parent 1:10 handle 10:0 sfq tc class add dev eth0 parent 1:1 classid 1:20 htb rate 8kbit ceil 8kbit tc qdisc add dev eth0 parent 1:20 handle 20:0 sfq tc class add dev eth0 parent 1:1 classid 1:30 htb rate 8kbit ceil 8kbit tc qdisc add dev eth0 parent 1:30 handle 30:0 sfq tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip dst 192.168.10.163 flowid 1:10 tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match u32 0x11e6bd53 0xffffffff at -12 match u16 0x0011 0xffff at -14 flowid 1:20 If I am to Throttle down the Leaf class Bandwidth to 3kbit what should be the value of root qdisc r2q?? and what should be the value of root class quantum??
