Bandwidth Management
This chapter contains information about configuring bandwidth management, editing rules and 
viewing the P-660HWP-Dx’s bandwidth management logs.
15.1  Bandwidth Management Overview 
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 P-660HWP-Dx applies bandwidth management to traffic that it forwards out through an 
interface. The P-660HWP-Dx 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 P-660HWP-Dx 
and be managed by bandwidth management. 
The sum of the bandwidth allotments that apply to any interface must be less than or equal to 
the speed allocated to that interface in the Bandwidth Management > Summary screen.
15.2  Application-based Bandwidth Management
You can create bandwidth classes based on individual applications (like VoIP, Web, FTP, E-
mail and Video for example).
15.3  Subnet-based Bandwidth Management
You can create bandwidth classes based on subnets.
The following figure shows LAN subnets. You could configure one bandwidth class for 
subnet A and another for subnet B
