Traffic Classes

On the Traffic Classes page, you can configure the mapping of frame priority tags to each port's four CoS priority queues.
For each port or trunk, the IEEE 802.1p priority level (from 0 to 7) listed in the Priority column can be mapped to one of the port's four traffic class queues
(from 0 to 3). The number 0 represents a low priority and higher values represent higher priorities.
