Media Bandwidth Management 20-7
20.7.2 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.
