23.7.2 Maximize Bandwidth Usage With Bandwidth Borrowing
If you configure both maximize bandwidth usage (on the interface) and bandwidth borrowing
(on individual child-classes), the Prestige functions as follows.
1 The Prestige sends traffic according to each bandwidth class’s bandwidth budget.
2 The Prestige assigns a parent class’s unused bandwidth to its child-classes that have more
traffic than their budgets and have bandwidth borrowing enabled. The Prestige gives
priority to bandwidth child-classes of higher priority and treats bandwidth classes of the
same priority equally.
3 The Prestige assigns any remaining unused or unbudgeted bandwidth on the interface to
any bandwidth class that requires it. The Prestige gives priority to bandwidth classes of
higher priority and treats bandwidth classes of the same level equally.
4 The Prestige assigns any remaining unbudgeted bandwidth to traffic that does not match
any of the bandwidth classes.
