I want to shape traffic from some IPs in my lan, but I'm w/ trouble. = I have a linux box connected to the Internet. In the other side of this = box is my LAN.

They are getting 512Kbit/s together.=20 I want limit this speed at 384Kbit/s, so traffic from each machine will = never be more than 192Kbps when both are in use. Why it is not working for me ???

Hi.

I want to shape = traffic=20 from some IPs in my lan, but I'm w/ trouble. I have a linux box = connected to the=20 Internet. In the other side of this box is my LAN. I want to create the=20 following scenario:

My root qdisc is attached to a 100Mbit/s NIC

I want to create a class attached to this qdisc that will limit=20 the traffic at 384Kbit/s.

I want to create two leaf classes that limits the traffic = at=20 256Kbit/s.

I want to attach two sfq qdiscs so two classes are treated=20 equally.

I want to put one LAN IP for each leaf class.

When one IP is downloading a file from internet it will never be = more than=20 256Kbit.

When both IPs is downloading files at the same time, they will = never be=20 more than 384Kbit.

(I think that is something like the webserver + smtp example = that is=20 in the howto)

My config:

tc qdisc add dev eth1 root handle 1:0 cbq bandwidth 100Mbit avpkt = 1000 cell=20 8
tc class add dev eth1 parent 1:0 classid 1:1 cbq bandwidth 100Mbit = rate=20 384Kbit weight 38Kbit prio 8 allot 1514 cell 8 maxburst 20 avpkt 1000=20 bounded

tc class add dev eth1 parent 1:1 classid 1:10 cbq bandwidth 100Mbit = rate=20 256Kbit weight 25Kbit prio 8 allot 1514 cell 8 maxburst 20 avpkt = 1000
tc=20 class add dev eth1 parent 1:1 classid 1:20 cbq bandwidth 100Mbit rate = 256Kbit=20 weight 25Kbit prio 8 allot 1514 cell 8 maxburst 20 avpkt 1000

tc qdisc add dev eth1 parent 1:10 handle 100: sfq
tc qdisc add = dev eth1=20 parent 1:20 handle 200: sfq

tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32 match ip = dst=20 10.0.0.2/32 flowid 1:10
tc filter add dev eth1 parent 1:0 protocol ip = prio 1=20 u32 match ip dst 10.0.0.3/32 flowid 1:20

When I start a download from one machine, the speed is limited at = 256Kbit/s=20 (this is OK)

When I start a download from both machines, the speed for each = machine is=20 limited to 256Kbit/s. They are getting 512Kbit/s together.

I want limit this speed at 384Kbit/s, so traffic from each machine = will=20 never be more than 192Kbps when both are in use.

Why it is not working for me ??? What is the mistake ?

Thank You.

Ricardo
