QoS Configuration Page
This page provides configuration for the Quality of Service (QoS) feature (not available on all
models). QoS is a network prioritizing feature that ensures high-priority traffic transfers during peak
capacity demands. The priority hierarchy is adhered to when capacity demand is higher than the link
can provide; highest priority traffic is allowed to transfer, while lowest priority traffic may be dropped.
Figure 36 QoS Configuration page (multiple Ethernet interface model)
These systems follow a ‘round robin’ QoS algorithm, ensuring a distribution of priority traffic. Some
percentage of all priority classifications is carried across the link, with the largest percentage applied to
the highest priority, and next largest percentage to the next highest priority, and so on. Thus low-
priority traffic is not ignored when there is a high capacity high-priority traffic stream.
The following QoS Mode options are available (choose one per port):
•
MAC DA (Media Access Control Destination Address): Prioritizes traffic based on the MAC
destination address (recipient of the traffic) in the packet header.
