LARTC - Mar 2005 - how to bring down htb rate to 3kbit?

Hello Everybody,

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??

Plz Plz Help

 Hi , Kartheek 
http://www.docum.org/docum.org/faq/cache/31.html 
 I think this may help you . The way i understand it  , quantum = rate / r2q , 
so you must set only quantum , r2q only helps "tc" for quantums
calculation .
Correct me if i am wrong .
