18.3.1 Bandwidth Manager Class Configuration
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
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 Section 18.3.1.1 on page 360).
The total of the bandwidth allotments for sub-classes cannot exceed the bandwidth allotment
of their parent class. The LAN-Cell uses the scheduler to divide a parent class’s unused
bandwidth among the sub-classes.

Enabled classes
Search Order
This list displays the interface’s active bandwidth management classes (the ones
that have the bandwidth filter enabled). The LAN-Cell applies the classes in the
order that they appear here. Once a connection matches a bandwidth management
class, the LAN-Cell applies the class’s rules and does not check the connection
against any other bandwidth management classes.
Search Order This is the index number of an individual bandwidth management class.
Class Name This is the name that identifies a bandwidth management class.
Service This is the service that this bandwidth management class is configured to manage.
Destination IP
Address
This is the destination IP address for connections to which this bandwidth
management class applies.
Destination Port This is the destination port for connections to which this bandwidth management
class applies.
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.
