The root qdisc bandwidth *should* be set smaller than the : bandwidth of the device by about 5% Well, wouldn't you say it depends on the qdisc in use? If you are using CBQ, see the comments in section 9.5.4, "The famous CBQ qdisc": http://lartc.org/howto/lartc.qdisc.classful.html In short, you'll use the bandwidth parameter to both your "tc qdisc add" and your "tc class add" commands. But, if you are using HTB, Steve is partly correct. Under HTB, you do not specify the real device bandwidth, but rather the rate to which you wish to limit your transmitted traffic. And in this case, it is wise to set the rate a bit lower than the real bandwidth to ensure that the HTB qdisc/classes are the bottleneck between the networks. -Martin -- Martin A.
