Wizard Setup for Media
Bandwidth Management
This chapter shows you how to configure basic bandwidth management using the wizard
screens.
4.1 Introduction
The web configurator’s Media Bandwidth Magnt. screens under Wizard Setup allows you
to specify bandwidth classes based on an application (or service). You can allocate specific
amounts of bandwidth capacity (bandwidth budgets) to different bandwidth classes.
The Prestige applies bandwidth management to traffic that it forwards out through an
interface. The Prestige does not control the bandwidth of traffic that comes into an interface.
Bandwidth management applies to all traffic flowing out of the Prestige through the interface,
regardless of the traffic's source.
Traffic redirect or IP alias may cause LAN-to-LAN traffic to pass through the Prestige and be
managed by bandwidth management.
Refer to Chapter 23, “Media Bandwidth Management Advanced Setup for more information
and advanced configuration.
