It is try to control outgoing traffic from machine.He is my config: tc qdisc add dev eth0 root handle 1: cbq bandwidth 100Mbit avpkt 1000 tc class add dev eth0 parent 1: classid 1:1 cbq bandwidth 100Mbit \ rate 100Mbit allot 1514 weight 1Mbit prio 8 maxburst 100 avpkt 1000 \ isolated bounded tc qdisc add dev eth0 parent 1:1 handle 2: cbq bandwidth 100Mbit avpkt 1000 #class for 192.168.1.5 tc class add dev eth0 parent 2: classid 2:5000 cbq bandwidth 100Mbit \ rate 70Mbit allot 1514 weight 200Kbit prio 2 maxburst 100 avpkt 1000 #class for 192.168.1.6 tc class add dev eth0 parent 2: classid 2:5001 cbq bandwidth 100Mbit \ rate 10Mbit allot 1514 weight 200Kbit prio 2 maxburst 100 avpkt 1000 tc qdisc add dev eth0 parent 2:5001 tbf rate 10Mbit buffer 45Kb/8 limit 15Kb tc filter add dev eth0 parent 1: protocol ip prio 6 u32 \ match ip src 192.168.1.5 flowid 1:1 tc filter add dev eth0 parent 1: protocol ip prio 6 u32 \ match ip src 192.168.1.6 flowid 1:1 tc filter add dev eth0 parent 2: protocol ip prio 5 u32 \ match ip src 192.168.1.5 flowid 2:5000 tc filter add dev eth0 parent 2: protocol ip prio 5 u32 \ match ip src 192.168.1.6 flowid 2:5001 Question: Now i am trying to see changes in rate when priority of class changes.But nothing happened.
