 Chapter 16 Bandwidth Management

NBG-417N User’s Guide

Traffic with a higher priority gets through faster while traffic with a lower priority is 
dropped if the network is congested.

The following describes the priorities that you can apply to traffic that the NBG-
417N forwards out through an interface.

Specific Port

This displays the port/s assigned to the service.

You can also specify the port/s to services to which you want to allocate 
bandwidth. Choose either Both, TCP or UDP in the drop-down menu 
and enter the port or range of ports in the provided boxes.

Note: If you are entering a specific port and not a range of ports, 

you can either leave the second port field blank or enter the 
same port number again.

Bandwidth 
Allocation

To LAN applies bandwidth management to traffic from WAN to LAN/
WLAN (i.e., downlink). 

To WAN applies bandwidth management to traffic from LAN/WLAN to 
WAN (i.e., uplink). 

Both applies bandwidth management to traffic that the NBG-417N 
forwards to both the LAN and the WAN. 

Port Range

This displays the range of ports for which the bandwidth management 
rule applies.

Policy

This displays either Max (maximum) or Min (minimum) and refers to 
the maximum or minimum bandwidth allowed for the rule in kilobits per 
second in the field below. 

Rate

This is the maximum or minimum bandwidth allowed (refer to the field 
above) for the rule in bits per second.
