Chapter 19 Bandwidth Management

253

This chapter contains information about configuring bandwidth management, editing rules and 
viewing the ZyXEL Device’s bandwidth management logs.

ZyXEL’s Bandwidth Management allows you to specify bandwidth management rules based 
on an application and/or subnet. You can allocate specific amounts of bandwidth capacity 
(bandwidth budgets) to different bandwidth rules. 

The ZyXEL Device applies bandwidth management to traffic that it forwards out through an 
interface. The ZyXEL Device does not control the bandwidth of traffic that comes into an 
interface.

Bandwidth management applies to all traffic flowing out of the router, regardless of the 
traffic's source.

Traffic redirect or IP alias may cause LAN-to-LAN traffic to pass through the ZyXEL Device 
and be managed by bandwidth management. 

• The sum of the bandwidth allotments that apply to the WAN interface (LAN to WAN, 

WLAN to WAN) must be less than or equal to the WAN speed that you configure in the 
Bandwidth Management Summary screen. 

• The sum of the bandwidth allotments that apply to the LAN port (WAN to LAN, WLAN 

to LAN) must be less than or equal to the LAN speed that you configure in the 
Bandwidth Management Summary screen. 

• The sum of the bandwidth allotments that apply to the WLAN port (LAN to WLAN, 

WAN to WLAN) must be less than or equal to the WLAN speed that you configure in the 
Bandwidth Management Summary screen. 

You can create bandwidth classes based on individual applications (like VoIP, Web, FTP, E-
mail and Video for example).

You can create bandwidth classes based on subnets.
