Hi All,

I was using CBQ to control the bandwidth rate , while i use the qdisc cbq with u32 filter and route filter it is 
working fine ,but when i use fw classifier it seems that the bandwidth rate 100kbit is not picked.

i have used the following commands 

/sbin/iptables -I PREROUTING -t mangle -p tcp -d 172.16.1.81 -j MARK --set-mark 1

/sbin/tc qdisc add dev eth0 root handle 1: cbq bandwidth 10Mbit cell 8 avpkt 1000 mpu 64
/sbin/tc class add dev eth0 parent 1:0 classid 1:1 cbq bandwidth 10Mbit rate 10Mbit allot 1514 cell 8 weight 1Mbit prio 8 maxburst 20 avpkt 1000
/sbin/tc class add dev eth0 parent 1:1 classid 1:2 cbq bandwidth 10Mbit rate 100Kbit allot 1514 cell 8 weight 10Kbit prio 3 maxburst 20 avpkt 1000

/sbin/tc filter add dev eth0 protocol ip parent 1:0 prio 1 handle 1 fw classid 1:2


is that anything i have missed out ?
i have tested these commands using Linux-2.4.10.

Advance Thanks
Vanitha

please use
tc -s qdisc show dev eth1
tc -s class show dev eth1
tc -s filter show dev eth1

to see where the packet goes ,
or how much it borrows .....
It seems your script can't regular the classid 1:2



cheers

According to the results ,
packets are not filtered into  classid 1:2
what is your testing scenario ?

(notice , PREROUTING don't tack care of local generating packets )

I have another query
