Change of bandwidth requires global recalculation of all the parameters and invalidates paratmeters set by user. > Is there any explanation or fix or workaround? Not a fix or workaround, but the only way to do this. If you need to change bandwidth, delete cbq and create new tree with other rates etc. Actually, I do not think that you really wanted to change this, I never heard about 50Mbit ethernet. :-) Alexey - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
