I want to do it and make a config

----------------------------------------------------------------------------
--------------------
BANDWIDTH="bandwidth 10Mbit"
RATE="rate 2Mbit"
DEV="dev eth1"
AVP="avpkt 1000"

tc qdisc add $DEV root handle 10: cbq $BANDWIDTH $AVP

tc class add $DEV parent 10:0 classid 10:1 cbq $BANDWIDTH $RATE \
allot 1514 weight 200Kbit prio 5 maxburst 20 $AVP \
bounded

tc qdisc add $DEV parent 10:1 handle 20: cbq bandwidth 2Mbit $AVP

tc class add $DEV parent 20:0 classid 20:1 cbq bandwidth 2Mbit $RATE \
allot 1514 weight 200Kbit prio 5 maxburst 20 $AVP \
bounded


tc filter add $DEV parent 20:0 protocol ip prio 100 u32 match ip src \
$IP flowid 20:1
----------------------------------------------------------------------------
--------------------
but it''s not active....the bandwidth is still 10Mbit....
Is my config''s error?????
