Hello Everyone :), i''m using cbq.init version 7.1 for traffic shaper, the rule did work well with flat rule (without parent/child)..here the condition of my network : - have a DMZ (and i not want the traffic to DMZ be bounded) - i made the CBQ engine also a bridge and i put it before NAT server (so if anything goes wrong i just shut down the engine and move the cable :p) my current configuration : #cbq-99.DMZINT DEVICE=eth1,100Mbit,10Mbit RATE=100Mbit WEIGHT=10Mbit PRIO=5 RULE=10.200.200.0/24,10.0.0.0/8 #cbq-101.A DEVICE=eth1 RATE=200Kbit WEIGHT=20Kbit PRIO=5 RULE=10.21.0.0/24 #cbq-102.S/W DEVICE=eth1 RATE=200Kbit WEIGHT=20Kbit PRIO=5 RULE=10.22.0.0/16 RULE=10.20.0.0/16 #cbq-103.H/W DEVICE=eth1 RATE=150Kbit WEIGHT=15Kbit PRIO=5 RULE=10.21.4.0/24 #cbq-104.WC DEVICE=eth1 RATE=200Kbit WEIGHT=20Kbit PRIO=5 RULE=10.21.77.0/24 RULE=10.21.78.0/24 This rule running well :) The problem is...every time i try to make a hierarchical class (with parent), it is always failed configuration that i tried : #cbq-99.DMZINT DEVICE=eth1,100Mbit,10Mbit RATE=100Mbit WEIGHT=10Mbit PRIO=5 RULE=10.200.200.0/24,10.0.0.0/8 #cbq-50.parent DEVICE=eth1 RATE=100Mbit WEIGHT=10Mbit PRIO=5 RULE=10.0.0.0/8 #cbq-101.A DEVICE=eth1 RATE=200Kbit WEIGHT=20Kbit PRIO=5 PARENT=50 LEAF=none (is this right conf ?) BOUNDED=none (is this ? ) RULE=10.21.0.0/24 #cbq-102.S/W DEVICE=eth1 RATE=200Kbit WEIGHT=20Kbit PRIO=5 PARENT=50 LEAF=none (is this right conf ?)
