<PRE>Hi all,
The script below works partially. Please help me figure out why.

What happen is this:
1.    Split eth0 into 2 classes; Sales and Engine.  --&gt; depth 1
2.    Split further Sales into 2 classes; SalesMan and SalesManager.  --&gt;
depth2
3.    Run the script.
4.    TC to depth 1 Engine works. Limited bandwidth.
5.    TC to depth 2 Sales DOESN'T work. Gets all the bandwidth.

Apparently, after further test, it shows that once I split more than once,
traffic control breaks down.
I hope you can help me figure out if my script is missing something... or
that is it a bug in the code itself??

Regards,
Rick Goh.
