LARTC - Feb 2006 - unable to get download restrictions working on an interface

I am using the following commands to restrict download on an interface vm01

/sbin/tc qdisc add dev vm01 root handle 11: cbq bandwidth 100Mbit avpkt 1000
mpu 64
/sbin/tc class add dev vm01 parent 11:0 classid 11:1 cbq rate 1.5Kbit weight
1.5Kbit allot 1514 prio 1 avpkt 1000 bounded
/sbin/tc filter add dev vm01 parent 11:0 protocol ip handle 4 fw flowid 11:1

When i do a qdisc show and class show, it shows me the information.

tc -s -d qdisc show dev vm01; tc -s -d class show dev vm01
qdisc cbq 11: rate 100Mbit cell 8b mpu 64b (bounded,isolated) prio
no-transmit/8 weight 100Mbit allot 1514b
level 1 ewma 5 avpkt 1000b maxidle 2us
 Sent 0 bytes 0 pkts (dropped 0, overlimits 0 requeues 0)
  borrowed 0 overactions 0 avgidle 65 undertime 0
class cbq 11: root rate 100Mbit cell 8b mpu 64b (bounded,isolated) prio
no-transmit/8 weight 100Mbit allot 1514b
level 1 ewma 5 avpkt 1000b maxidle 2us
 Sent 0 bytes 0 pkts (dropped 0, overlimits 0 requeues 0)
  borrowed 0 overactions 0 avgidle 65 undertime 0
class cbq 11:1 parent 11: rate 187bit cell 8b (bounded) prio 1/1 weight
192bit allot 1514b
level 0 ewma 5 avpkt 1000b maxidle 2us
 Sent 0 bytes 0 pkts (dropped 0, overlimits 0 requeues 0)
  borrowed 0 overactions 0 avgidle 0 undertime 0

When traffic flows through the interface vm01 and a watch is placed on the
above results, it shows traffic is flowing however the restrictions placed
by the commands don''t seem to be working. No matter what i use, the
interface is able to get the max bandwidth available.

Can anyone please help me in getting this right ?

Thanks.
