Bandwidth Management Wizard
This chapter shows you how to configure basic bandwidth management using the wizard
screens.
4.1 Introduction
Bandwidth management allows you to control the amount of bandwidth going out through the
ZyXEL device’s WAN port and prioritize the distribution of the bandwidth according to
service bandwidth requirements. This helps keep one service from using all of the available
bandwidth and shutting out other users.
4.2 Predefined Media Bandwidth Management Services
