What exactly happens if the sum of the children classes rate is bigger than the parent''s? What if the majority of these classes are using less than the minimum rate established (eg. 0kbps)? -- Marco Casaroli SapucaiNet Telecom +55 35 34712377 ext 5

Hi,>What exactly happens if the sum of the children classes rate is bigger >than the parent''s?I would say that in most cases it would be a misconfiguration, especially if you have more layers of HTB classes. The bw you configure with rate is not going to be reserved properly if you do not respect the rule rate(parent)>=Sum of rates(children). Anyway, the parent node does not throttle the children classes. Parents are there mainly to allow borrowing and sharing between sibling/descendant classes.>What if the majority of these classes are using less than the minimum >rate established (eg. 0kbps)?Why should this be a problem? In this case a class simply uses less than what it has been allocated. Depending on your configuration, other classes would probably be able to borrow more. Regards /Christian [ http://benve.info ]
