Hello! tc-htb is great because its easy, but you cannot specify an mpu. Thats bad, because with the mpu you can specify the physical characteristics of the underlying connection. I have a braodband dsl-connection. I have the problem that the proportion of small packets to big packets changes a lot. So without specifing the mpu the connection is not to full capacity (big packets) or the buffer of the modem will be filled (small packets). Can i append an tc-tbf qdisc (qdisc 30:) to an tc-htb class with specifiying an mpu? I already did so for increasing the queue for big packets (qdisc 20:), but when i tried this for small packets i could not direct data with an tc filter to it, it alway go to qdisc 20:. tc tree Configuration: root qdisc htb class 1 htb class 1:10 htb qdisc 20: tbf class 1:11 htb qdisc 30: tbf tc filter: tc filter add dev $dev protocol ip handle 10 \ fw flowid 20: tc filter add dev $dev protocol ip handle 11 \ fw flowid 30: I don´t know how those queue work, if you specify the mpu in 20: or 30: will the parent classes work with the calculated size of the packets? Anyway, traffic was not directed in 30: :( any suggestions? Great thanks in advance Alvo _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
