Hi,
Can someone explain me what this script does?
tc qdisc del dev eth1 root
tc qdisc add dev eth1 root handle 1:0 cbq bandwidth 10mbit avpkt =
1000
tc class add dev eth1 parent 1:0 classid 1:39 cbq bandwidth 256kbit =
rate 128kbit allot 1514 maxburst 20 avpkt 1000
tc class add dev eth1 parent 1:0 classid 1:40 cbq bandwidth 256kbit =
rate 128kbit allot 1514 maxburst 20 avpkt 1000
tc class add dev eth1 parent 1:0 classid 1:41 cbq bandwidth 256kbit =
rate 128kbit allot 1514 maxburst 20 avpkt 1000
tc class add dev eth1 parent 1:0 classid 1:47 cbq bandwidth 256kbit =
rate 128kbit allot 1514 maxburst 20 avpkt 1000
tc class add dev eth1 parent 1:0 classid 1:48 cbq bandwidth 256kbit =
rate 128kbit allot 1514 maxburst 20 avpkt 1000
tc class add dev eth1 parent 1:0 classid 1:49 cbq bandwidth 256kbit =
rate 128kbit allot 1514 maxburst 20 avpkt 1000
tc class add dev eth1 parent 1:0 classid 1:50 cbq bandwidth 256kbit =
rate 128kbit allot 1514 maxburst 20 avpkt 1000
tc filter add dev eth1 parent 1:0 protocol ip prio 1 handle 0 =
tcindex classid 1:50
tc filter add dev eth1 parent 1:0 protocol ip prio 39 handle 39 =
tcindex classid 1:39
tc filter add dev eth1 parent 1:0 protocol ip prio 40 handle 40 =
tcindex classid 1:40
tc filter add dev eth1 parent 1:0 protocol ip prio 41 handle 41 =
tcindex classid 1:41
tc filter add dev eth1 parent 1:0 protocol ip prio 47 handle 47 =
tcindex classid 1:47
tc filter add dev eth1 parent 1:0 protocol ip prio 48 handle 48 =
tcindex classid 1:48
tc filter add dev eth1 parent 1:0 protocol ip prio 49 handle 49 =
tcindex classid 1:49
I think it will devide the traffic in the different classes according to =
the tcindex value. However, the script doesn't use a dsmark qdisc, so =
the tcindex value should be set first with an ingress qdisc, right?
thx,
Jan
