Hi Vanitha,

Thanks for the help!  It is still not working.

I have changed the following line and added the

tc class add  dev eth0 parent 1:1 classid 1:2 cbq bandwidth 100Mbit rate 
20Mbit allot 1514 cell 8 avpkt 1000  weight 2Mbit prio 5 maxburst 20 bounded

Here is the the results of "tc -s -s class sh dev eth0":

---------------------------------------------------------------------

Instead of flowid 2:2, all traffics went to root 1:0. 
Maybe, my filters are not correct. ??

Thanks,
