Hi,

Can someone explain me what this script = does?

tc qdisc del dev = eth1=20 root

tc qdisc add dev = eth1 root=20 handle 1:0 cbq bandwidth 10mbit avpkt 1000

    tc class add dev = eth1 parent 1:0=20 classid 1:39 cbq bandwidth 256kbit rate 128kbit allot 1514 maxburst 20 = avpkt=20 1000
    tc class add dev eth1 parent 1:0 classid 1:40 = cbq=20 bandwidth 256kbit rate 128kbit allot 1514 maxburst 20 avpkt=20 1000
    tc class add dev eth1 parent 1:0 classid 1:41 = cbq=20 bandwidth 256kbit rate 128kbit allot 1514 maxburst 20 avpkt=20 1000
    tc class add dev eth1 parent 1:0 classid 1:47 = cbq=20 bandwidth 256kbit rate 128kbit allot 1514 maxburst 20 avpkt=20 1000
    tc class add dev eth1 parent 1:0 classid 1:48 = cbq=20 bandwidth 256kbit rate 128kbit allot 1514 maxburst 20 avpkt=20 1000
    tc class add dev eth1 parent 1:0 classid 1:49 = cbq=20 bandwidth 256kbit rate 128kbit allot 1514 maxburst 20 avpkt=20 1000
    tc class add dev eth1 parent 1:0 classid 1:50 = cbq=20 bandwidth 256kbit rate 128kbit allot 1514 maxburst 20 avpkt = 1000

    tc filter add dev = eth1 parent=20 1:0 protocol ip prio 1 handle 0 tcindex classid = 1:50
    tc=20 filter add dev eth1 parent 1:0 protocol ip prio 39 handle 39 tcindex = classid=20 1:39
    tc filter add dev eth1 parent 1:0 protocol ip = prio 40=20 handle 40 tcindex classid 1:40
    tc filter add dev = eth1=20 parent 1:0 protocol ip prio 41 handle 41 tcindex classid=20 1:41
    tc filter add dev eth1 parent 1:0 protocol ip = prio 47=20 handle 47 tcindex classid 1:47
    tc filter add dev = eth1=20 parent 1:0 protocol ip prio 48 handle 48 tcindex classid=20 1:48
    tc filter add dev eth1 parent 1:0 protocol ip = prio 49=20 handle 49 tcindex classid 1:49

I think it will devide the traffic in = the different=20 classes according to the tcindex value. However, the script doesn't use = a dsmark=20 qdisc, so the tcindex value should be set first with an ingress = qdisc,=20 right?

thx,

Jan
