18.1.3.6 Fairness-based Allotment of Unused and Unbudgeted Bandwidth Example
The following table shows the amount of bandwidth that each class gets.
Suppose that all of the classes except for the administration class need more bandwidth.
• Each class gets up to its budgeted bandwidth. The administration class only uses 1024
kbps of its budgeted 2048 kbps.
• The LAN-Cell divides the total 3072 kbps total of unbudgeted and unused bandwidth
equally among the other classes. 1024 kbps extra goes to each so the other classes each get
a total of 3072 kbps.
18.1.3.7 Reserving Bandwidth for Non-Bandwidth Class Traffic Example
Do the following three steps to configure the LAN-Cell to allow bandwidth for traffic that is
not defined in a bandwidth filter.
1 Leave some of the interface’s bandwidth unbudgeted.
2 Do not enable the interface’s Maximize Bandwidth Usage option.
3 Do not enable bandwidth borrowing on the sub-classes that have the root class as their
parent (see Section on page 357).
18.2 Bandwidth Management Summary Screen
Click ADVANCED > BW MGMT to open the Summary screen.
Enable bandwidth management on an interface and set the maximum allowed bandwidth for
that interface.
