203 Chapter 19 Bandwidth Management
19.9.1 Bandwidth Borrowing Example
Here is an example of bandwidth management with classes configured for bandwidth
borrowing. The classes are set up based on departments and individuals within certain
departments.
• The Sales class cannot borrow unused bandwidth from the Root class because the Sales
class has bandwidth borrowing disabled.
19.9.2 Maximize Bandwidth Usage With Bandwidth Borrowing
If you configure both maximize bandwidth usage (on the interface) and bandwidth borrowing
(on individual sub-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 sub-classes that have more
traffic than their budgets and have bandwidth borrowing enabled. The Prestige gives
priority to sub-classes of higher priority and treats classes of the same priority equally.
3 The Prestige assigns any remaining unused or unbudgeted bandwidth on the interface to
any class that requires it. The Prestige gives priority to classes of higher priority and
treats classes of the same level equally.
4 If the bandwidth requirements of all of the traffic classes are met and there is still some
unbudgeted bandwidth, the Prestige assigns it to traffic that does not match any of the
classes.
