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.

16.5.1 Priority Levels

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.

•High - Typically used for voice traffic or video that is especially sensitive to jitter (jitter is the variations in delay).

•Low - This is typically used for all other traffic that are not time-sensitive.
