Hi list, I'm in trouble with a scenario and would like to know if you 
guys can help me explain and work it out:

I need to put some customers in a class of, lets say, 1Mbit/s and try to 
garantee then a percentage of the bandwith. So I came up with the 
following scenario

# root stuff
tc qdisc add dev eth0 root handle 1: htb default 2
tc class add dev eth0 parent 1: classid 1:1 htb rate 50000kbit
# default class
tc class add dev eth0 parent 1: classid 1:2 htb rate 2000kbit

# root class for this "garanteed bandwidth" service
tc class add dev eth0 parent 1: classid 1:3 htb rate 10Mbit

# class for this 1Mbit shared bandwidth
tc class add dev eth0 parent 1:3 classid 1:1024 htb rate 1Mbit
# qdisc used to _make my life easier numbering customer classes_
tc qdisc add dev eth0 parent 1:1024 handle 1024: htb default 250
# default class for this second qdisc
tc class add dev eth0 parent 1024: classid 1024:250 htb rate 32kbit

# each customer gets the following class and filter
tc class add dev eth0 parent 1024: classid 1024:1 htb rate 256kbit
tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip dst 
xxx.xxx.xxx.xxx/yy flowid 1024:1

# another customer...
tc class add dev eth0 parent 1024: classid 1024:2 htb rate 256kbit
tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip dst 
www.www.www.www/zzz flowid 1024:2


First, this filters doesn't work, all traffic goes to 1:2. Why? I can 
filter traffic to any class at 1:? but not to classes below the second 
qdisc (1:1024).

Shouldn't I make this filter pointing to 1024: as the parent? It doesn't 
let me do it...

Any help?

Tks for you help and attention.
