Chapter 21 Bandwidth Management Screens

ZyWALL 2WG User’s Guide

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.
Refer to the product specifications in the appendix to see how many class levels you can 
configure on your ZyWALL. 

• The Bill class can borrow unused bandwidth from the Sales USA class because the Bill 

class has bandwidth borrowing enabled.

• The Bill class can also borrow unused bandwidth from the Sales class because the Sales 

USA class also has bandwidth borrowing enabled.

• The Bill class cannot borrow unused bandwidth from the Root class because the Sales 

class has bandwidth borrowing disabled.

• The Amy class cannot borrow unused bandwidth from the Sales USA class because the 

Amy class has bandwidth borrowing disabled.

• The Research Software and Hardware classes can both borrow unused bandwidth from the 

Research class because the Research Software and Hardware classes both have bandwidth 
borrowing enabled.
