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.

Re: [LARTC] priorizing vlans in a bridge
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?

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 ___ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
