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.

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?

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.
