Hello!

I've been trying to write a traffic shaper for a 128kbit line with this setup 
:
5 computers that get dedicated bandwidth and the rest go in a pool with bigger 
priorities.

I made the attached script, but it seems it doesn't work...

It sends the traffic coming from the dedicated ips to the default class.
Where is the error ?

Will this setup work if the bandwidth is full ? 
Since it's not a guaranteed bandwidth can  i put no ceiling but still all the 
ips to have their equal share ?

I've set r2q to 1 (it's the smallest one possible, no ? ) and it receive 
warnings that the quantum is too small

Thanks in advance....

Radu

Here's the script :

tc qdisc add dev eth1 root handle 1: htb default 14  r2q 1
tc class add dev eth1 parent 1: classid 1:1 htb rate 128kbit burst 2k
tc class add dev eth1 parent 1:1 classid 1:10 htb rate 48kbit burst 2k

tc class add dev eth1 parent 1:1 classid 1:20 htb rate 12kbit ceil 128kbit 
burst 2k

tc class add dev eth1 parent 1:1 classid 1:30 htb rate 12kbit ceil 128kbit 
burst 2k

tc class add dev eth1 parent 1:1 classid 1:40 htb rate 12kbit ceil 128kbit 
burst 2k

tc class add dev eth1 parent 1:1 classid 1:50 htb rate 12kbit ceil 128kbit 
burst 2k

tc class add dev eth1 parent 1:1 classid 1:11 htb rate 20kbit ceil 128kbit 
burst 2k

tc class add dev eth1 parent 1:11 classid 1:12 htb rate 10kbit  burst 2k
tc class add dev eth1 parent 1:11 classid 1:13 htb rate 5kbit   burst 2k
tc class add dev eth1 parent 1:11 classid 1:14 htb rate 5kbit   burst 2k
