I want to bring down the HTB rate to 3kbit-r2q? quantum?

[kartheek <kartheekpn@xxxxxxxxxxx>]

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??
