Hi list, I'm in trouble with a scenario and would like to know if you guys can help me explain and work it out: I need to put some customers in a class of, lets say, 1Mbit/s and try to garantee then a percentage of the bandwith. So I came up with the following scenario # root stuff tc qdisc add dev eth0 root handle 1: htb default 2 tc class add dev eth0 parent 1: classid 1:1 htb rate 50000kbit # default class tc class add dev eth0 parent 1: classid 1:2 htb rate 2000kbit # root class for this "garanteed bandwidth" service tc class add dev eth0 parent 1: classid 1:3 htb rate 10Mbit # class for this 1Mbit shared bandwidth tc class add dev eth0 parent 1:3 classid 1:1024 htb rate 1Mbit # qdisc used to _make my life easier numbering customer classes_ tc qdisc add dev eth0 parent 1:1024 handle 1024: htb default 250 # default class for this second qdisc tc class add dev eth0 parent 1024: classid 1024:250 htb rate 32kbit # each customer gets the following class and filter tc class add dev eth0 parent 1024: classid 1024:1 htb rate 256kbit tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip dst xxx.xxx.xxx.xxx/yy flowid 1024:1 # another customer... tc class add dev eth0 parent 1024: classid 1024:2 htb rate 256kbit tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip dst www.www.www.www/zzz flowid 1024:2 First, this filters doesn't work, all traffic goes to 1:2. Why? I can filter traffic to any class at 1:? but not to classes below the second qdisc (1:1024). Shouldn't I make this filter pointing to 1024: as the parent? It doesn't let me do it... Any help? Tks for you help and attention. ADC
