Tc does not seem to be limiting bandwidth

Hello:

I have these commands in my firewall startup script:

DEV=v1252
IP=a.b.c.d
/sbin/tc qdisc del dev $DEV root
/sbin/tc qdisc add dev $DEV root handle 1: htb default 30
/sbin/tc class add dev $DEV parent 1: classid 1:1 htb rate 10mbit
/sbin/tc class add dev $DEV parent 1: classid 1:2 htb rate 10mbit
/sbin/tc filter add dev $DEV protocol ip parent 1:0 prio 1 u32 match ip dst
$IP flowid 1:1
/sbin/tc filter add dev $DEV protocol ip parent 1:0 prio 1 u32 match ip src
$IP flowid 1:2

And tc qdisc list shows it has something for that dev:

qdisc htb 1: dev v1252 root refcnt 2 r2q 10 default 30 direct_packets_stat 3

But, I am still seeing huge consumption of bandwidth from that server.
Take a look at the attached graph.

Any ideas why tc is not limiting the bandwidth?

Thanks,
  Neil
