CBQ problem

this is my CBQ configuration:

DEV=eth1
tc qdisc del dev $DEV root
tc qdisc add dev $DEV root handle 1: cbq avpkt 100 bandwidth 10Mbit cell 8
tc class add dev $DEV parent 1: classid 1:1 cbq rate 10kbit allot 1500 prio
1 cell 8 bounded isolated
tc class add dev $DEV parent 1:1 classid 1:10 cbq rate 1Mbit allot 1500 prio
2 avpkt 15 bounded isolated
tc class add dev $DEV parent 1:1 classid 1:20 cbq rate 7Mbit allot 1500 prio
2 avpkt 60 bounded isolated
tc class add dev $DEV parent 1:1 classid 1:30 cbq rate 200kbit allot 1500
prio 2 avpkt 60 bounded isolated
tc qdisc add dev $DEV parent 1:10 handle 10: sfq perturb 10
tc qdisc add dev $DEV parent 1:20 handle 20: sfq perturb 10
tc qdisc add dev $DEV parent 1:30 handle 30: sfq perturb 10
tc filter add dev $DEV parent 1: protocol ip prio 1 u32 match u8 0x00 0x00
at 0 flowid 1:30
tc filter add dev $DEV parent 1: protocol qroute_uni prio 2 u32 match u8
0x40 0xff at 14 flowid 1:20
tc filter add dev $DEV parent 1: protocol qroute_multi prio 3 u32 match u8
0x40 0xff at 14 flowid 1:20
tc filter add dev $DEV parent 1: protocol qroute_uni prio 4 u32 match u8
0x00 0x00 at 14 flowid 1:10
tc filter add dev $DEV parent 1: protocol qroute_multi prio 5 u32 match u8
0x00 0x00 at 14 flowid 1:10

I want to shape class 1:1 to 10kbit, but it is not successfull. As I know
when class 1:1 is shaped to 10Kbits, its children, can not exceed it, even
if the child''s rate is more than class 1:1. But After I applied this tc
configuration, I notice that the bandwidth of class 1:30 is around 200Kbit
(not shape to less than 10Kbit). anyone can help me?

Re: CBQ problem

Some one told me that "bounded", and "isolated"
don''t work sometimes, is it
true?

I did some tests.  You can find the results on www.docum.org on the test page.  
I don''t have a direct link available to the page with the results.
