Pošlu ti kus sveho konfiguraku, snad to z toho pochopíš.

Pro vlastní studium doporučuji "man tc".

Nejdříve si nadefinuj kořenový flow:

wifiDev="wifi1"


echo WIFI RODGA
tc qdisc del dev $wifiDev root

tc qdisc add dev $wifiDev root handle 10: cbq bandwidth 2Mbit avpkt 1000
tc class add dev $wifiDev parent 10:0 classid 10:1 cbq bandwidth 2Mbit rate 2Mbit allot 1514 weight 1Mbit prio 8 maxburst 20 avpkt 1000

Pak k němu dodefinuj 3 flow pro 3 skupiny uživatelů


tc class add dev $wifiDev parent 10:1 classid 10:100 cbq bandwidth 2Mbit rate 512kbit allot 1514 weight 512Kbit prio 4 maxburst 20 avpkt 1000
tc class add dev $wifiDev parent 10:1 classid 10:200 cbq bandwidth 2Mbit rate 512kbit allot 1514 weight 512Kbit prio 5 maxburst 20 avpkt 1000
tc class add dev $wifiDev parent 10:1 classid 10:300 cbq bandwidth 2Mbit rate 512kbit allot 1514 weight 512Kbit prio 5 maxburst 20 avpkt 1000
tc class add dev $wifiDev parent 10:1 classid 10:700 cbq bandwidth 2Mbit rate 132kbit allot 1514 weight 128Kbit prio 4 maxburst 20 avpkt 1000
tc class add dev $wifiDev parent 10:1 classid 10:800 cbq bandwidth 2Mbit rate 196kbit allot 1514 weight 196Kbit prio 5 maxburst 20 avpkt 1000
tc class add dev $wifiDev parent 10:1 classid 10:900 cbq bandwidth 2Mbit rate 32kbit allot 1514 weight 32Kbit prio 5 maxburst 20 avpkt 1000 bounded

tc qdisc add dev $wifiDev parent 10:100 sfq quantum 1514b perturb 15
tc qdisc add dev $wifiDev parent 10:200 sfq quantum 1514b perturb 15
#tc qdisc add dev $wifiDev parent 10:201 sfq quantum 1514b perturb 15
tc qdisc add dev $wifiDev parent 10:300 sfq quantum 1514b perturb 15
tc qdisc add dev $wifiDev parent 10:700 sfq quantum 1514b perturb 15
tc qdisc add dev $wifiDev parent 10:800 sfq quantum 1514b perturb 15
tc qdisc add dev $wifiDev parent 10:900 sfq quantum 1514b perturb 15


No a nakonec nějaké klasifikátory, krerými přiřadíš procházející pakety do flow:
