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.
