4.8 QoS
The QoS function allows you to configure settings for the switch QoS interface and
how the switch connects to a remote server to get services.
4.8.1 General
Traditionally, networks operate on a best-effort delivery basis, all traffic has equal
priority and an equal chance of being delivered in a timely manner. When there is
congestion, all traffic has an equal chance of being dropped.
The QoS feature can be configured for congestion-management and congestion-
avoidance to specifically manage the priority of the traffic delivery. Implementing QoS
in the network makes performance predictable and bandwidth utilization much more
effective.
The QoS implementation is based on the prioritization values in Layer 2 frames.
