 Chapter 21 Bandwidth Management Screens

ZyWALL 2WG User’s Guide

Configure a bandwidth management class in the Class Setup screen. You must use the 
Summary screen to enable bandwidth management on an interface before you can configure 
classes for that interface.

Bandwidth borrowing allows a sub-class to borrow unused bandwidth from its parent class, 
whereas maximize bandwidth usage allows bandwidth classes to borrow any unused or 
unbudgeted bandwidth on the whole interface.
Enable bandwidth borrowing on a sub-class to allow the sub-class to use its parent class’s 
unused bandwidth. A parent class’s unused bandwidth is given to the highest priority sub-class 
first. The sub-class can also borrow bandwidth from a higher parent class (grandparent class) 
if the sub-class’s parent class is also configured to borrow bandwidth from its parent class. 
This can go on for as many levels as are configured to borrow bandwidth from their parent 
class (see 

). 

The total of the bandwidth allotments for sub-classes cannot exceed the bandwidth allotment 
of their parent class. The ZyWALL uses the scheduler to divide a parent class’s unused 
bandwidth among the sub-classes.
Click ADVANCED > BW MGMT > Class Setup > Add Sub-Class or Edit to open the 
following screen. Use this screen to add a child class.

Source IP 

Address

This is the source IP address for connections to which this bandwidth management 

class applies.

Source Port

This is the source port for connections to which this bandwidth management class 

applies.

Protocol ID

This is the protocol ID (service type) number for connections to which this 

bandwidth management class applies. For example: 1 for ICMP, 6 for TCP or 17 for 

UDP. 

Move

Type a class’s index number and the number for where you want to put that class. 

Click Move to move the class to the number that you typed. The ordering of your 

classes is important as they are applied in order of their numbering.
