Hi Junus Junarto D, I still have the same problem of limiting the outgoing traffic. I'm limiting the incoming traffic perfectily with the script: tc qdisc add dev eth1 root handle 1:0 cbq bandwidth 256Kbit avpkt 1000 cell 8 tc class add dev eth1 parent 1:0 classid 1:1 cbq bandwidth 256Kbit rate \ 256Kbit weight 20Kbit prio 8 allot 1514 cell 8 maxburst 20 avpkt 1000 tc class add dev eth1 parent 1:1 classid 1:10 cbq bandwidth 256Kbit rate \ 64Kbit weight 6Kbit prio 5 allot 1514 cell 8 maxburst 20 avpkt 1000 bounded tc qdisc add dev eth1 parent 1:10 tbf rate 64Kbit buffer 10Kb/8 limit 15Kb \ mtu 1500 tc filter add dev eth1 parent 1:0 protocol ip prio 100 u32 match ip dst \ 10.0.5.2 flowid 1:10 But when I try to limit the incoming traffic I still have the same problem that it does not limit. And I still doesn't know why. I used your and my script and everything happens like there is no shaper... The outgoing traffic script is: tc qdisc add dev eth0 root handle 2:0 cbq bandwidth 256Kbit avpkt 1000 \ cell 8 tc class add dev eth0 parent 2:0 classid 2:1 cbq bandwidth 256Kbit rate \ 256Kbit weight 20Kbit prio 8 allot 1514 cell 8 maxburst 20 avpkt 1000 tc class add dev eth0 parent 2:1 classid 2:10 cbq bandwidth 256Kbit rate \ 64Kbit weight 6Kbit prio 5 allot 1514 cell 8 maxburst 20 avpkt 1000 bounded tc qdisc add dev eth0 parent 2:10 tbf rate 64Kbit buffer 10Kb/8 limit \ 15Kb mtu 1500 tc filter add dev eth0 parent 2:0 protocol ip prio 100 u32 match ip src \ 10.0.5.2 flowid 2:10 But, thanx a lot...
