here is my skript. i want to priorize on first udp second icmp then tcp then any other how? does "tc qdisc add dev eth0 parent 1:12 handle 20: prio 1 udp " priorize udp? tc qdisc del dev eth0 root tc qdisc del dev eth1 root #eht0 rules tc qdisc add dev eth0 root handle 1: htb default 12 #shape interface eth0 tc class add dev eth0 parent 1: classid 1:1 htb rate 128kbit ceil 128kbit #voip class tc class add dev eth0 parent 1:1 classid 1:12 htb rate 128kbit ceil 128kbit #staff class tc class add dev eth0 parent 1:1 classid 1:11 htb rate 30kbit ceil 128kbit tc class add dev eth0 parent 1:1 classid 1:13 htb rate 30kbit ceil 128kbit #mark voip class tc filter add dev eth0 parent 1: protocol ip prio 1 handle 2 fw classid 1:12 #mark staff class tc filter add dev eth0 parent 1: protocol ip prio 1 handle 1 fw classid 1:11 tc filter add dev eth0 parent 1: protocol ip prio 1 handle 3 fw classid 1:13 #add qdisc discipline tc qdisc add dev eth0 parent 1:11 handle 30: sfq perturb 10 tc qdisc add dev eth0 parent 1:12 handle 20: sfq perturb 10 #eth1 rules tc qdisc add dev eth1 root handle 1: htb default 12 #shape eth1 interface tc class add dev eth1 parent 1: classid 1:1 htb rate 128kbit ceil 128kbit #voip class tc class add dev eth1 parent 1:1 classid 1:12 htb rate 128kbit ceil 128kbit #staff class tc class add dev eth1 parent 1:1 classid 1:11 htb rate 30kbit ceil 128kbit tc class add dev eth1 parent 1:1 classid 1:13 htb rate 30kbit ceil 128kbit #mark voip class tc filter add dev eth1 parent 1: protocol ip prio 1 handle 12 fw classid 1:12 #mark staff class tc filter add dev eth1 parent 1: protocol ip prio 1 handle 11 fw classid 1:11 tc filter add dev eth1 parent 1: protocol ip prio 1 handle 13 fw classid 1:13 #add qdisc discipline tc qdisc add dev eth1 parent 1:11 handle 30: sfq perturb 10 tc qdisc add dev eth1 parent 1:12 handle 20: sfq perturb 10
