Hi! I have a setup where I want to prefer traffic on one port (for testing purposes I used port 22) my setup is : tc qdisc add dev eth3 root handle 1: htb default 30 tc class add dev eth3 parent 1: classid 1:1 htb rate 96mbit burst 15k tc class add dev eth3 parent 1: classid 1:7 htb rate 2mbit burst 15k tc class add dev eth3 parent 1:1 classid 1:10 htb rate 96mbit burst 15k tc class add dev eth3 parent 1:7 classid 1:20 htb rate 1800kbit ceil 2mbit burst 15k tc class add dev eth3 parent 1:7 classid 1:30 htb rate 200kbit ceil 2mbit burst 15k tc qdisc add dev eth3 parent 1:10 handle 10: sfq perturb 10 tc qdisc add dev eth3 parent 1:20 handle 20: sfq perturb 10 tc qdisc add dev eth3 parent 1:30 handle 30: sfq perturb 10 U32="tc filter add dev eth3 protocol ip parent 1:0 prio 1 u32" $U32 match ip src 81.223.175.128/26 flowid 1:10 $U32 match ip dst 192.168.5.9 match ip sport 22 0xfff flowid 1:20 $U32 match ip dst 192.168.5.9 match ip dport 22 0xfff flowid 1:20 $U32 match ip dst 192.168.5.10 match ip sport 22 0xfff flowid 1:20 $U32 match ip dst 192.168.5.10 match ip dport 22 0xfff flowid 1:20 What would like to achieve is that trafic on port 22 has 1800kbit always, regardless of traffic on any other port, but if there is no traffic on port 22 the rest can claim the whole bandwidth (i.e. 2.3 mbit ). However if I set the ceiling to 2mbit on both, they seem to sher the bandwidth evenly. If I set the ceiling to 512k on 1:30, I get better performance on 1:20. Do I not understand the concept correctly? I assumes that the rate would give me the guaranteed bandwidth for each class, and the ceiling is there to make it use what's "left over" from the other classes. If someone could enlighten me, I would appreciate it.
