QoS Tab - CoS Settings

Class of Service (CoS) allows you to specify which data packets have greater precedence when
traffic is buffered in the switch due to congestion. The switch supports CoS with four priority
queues for each port. Data packets in a port's high-priority queue will be transmitted before
those in the lower-priority queues. You can set the default priority for each interface, and
configure the mapping of frame priority tags to the switch's priority queues.The priority levels
recommended in the IEEE 802.1p standard for various network applications are shown in the
following table. However, you can map the priority levels to the switch's output queues in any
way that benefits application traffic for your own network.
The CoS Settings screen contains fields for enabling or disabling CoS. In addition, the Trust
mode can be selected. The Trust mode relies on predefined fields within the packet to
determine the egress queue settings.
