Hi, this is my Linux Box

              ----------------------------
   LAN 1 -----|--eth1 <---br1--->eth0.1  |
              |                     \    |
              |                    eth0--|----- 802.1q tagged 1 Mbps link
              |                     /    |
   LAN 2 -----|--eth2 <---br2--->eth0.2  |
              ----------------------------

I have to bridge the 2 lans in the left side of the diagram with my linux box
running as a bridge. I have to tag the traffic of each lan so I created the 2
vlans interfaces on eth0 (tag 1 and tag 2).
All works fine. But now I have to priorize LAN1 traffic so it leaves the bridge
before LAN2. Also I need to shape the traffic to the 1 Mbps link.

I read about the "prio" qdisc but it honours the TOS field of the IP packets,
and I don't want to unless it was really necessary.
I read about the "prio" option of the htb qdisc and made some scripts, but they
don't work as I expected.

HTB script:

tc qdisc add dev eth0 root handle 1: htb
tc class add dev eth0 parent 1: classid 1:1 htb rate 1000kbit

tc class add dev eth0 parent 1:1 classid 1:11 htb rate 500kbit ceil 1000kbit prio 1
tc filter add dev eth0 parent 1: prio 1 protocol ip handle 1 fw classid 1:11
iptables -t mangle -A PREROUTING -i eth1 -j MARK --set-mark 1

tc class add dev eth0 parent 1:1 classid 1:12 htb rate 500kbit ceil 800kbit prio 2
tc filter add dev eth0 parent 1: prio 1 protocol ip handle 2 fw classid 1:12
iptables -t mangle -A PREROUTING -i eth2 -j MARK --set-mark 2

What do you suggest me?
Thanks in advance.

May be you could try to add :
tc filter add dev eth0 parent 1:0 protocol all u32 match u32 0 0 at 0
flowid 1:1 or some similar filter to get the whole flow from 1:0 to 1:1

Hi,

You should use eth0.1 and eth0.2 in your tc statements ...

If I use the vlans interfaces eth0.1 and eth0.2 in the tc statements, I would
have two independent root qdiscs on each interface, and this won´t let me
prioritize LAN1 over LAN2. That's why I set this up all on eth0, which is the
interface that sees all the entire traffic.
Any other idea?
Thanks for your answers

Prio in htb setup like this only really affects the borrowing of excess 
- rate is guaranteed. Also you need to back off a bit from your link 
speed to allow for overheads.

I would use something like rate 850kbit ceil 900kbit here

and rate 50kbit ceil 900kbit here.

Ok, with htb the priority is for borrowing of the free bandwidth. So what Qdisc
could help me to make a customized priority qdisc ?, so I could define for
example 4 or 8 bands not based on the TOS field like the prio qdisc.
