11.1 DiffServ This switch classifies the ingress packets, maps the packets to different priority queues and then forwards the packets according to specified scheduling algorithms to implement QoS function. This switch implements three priority modes based on port, on 802.1P and on DSCP, and supports four queue scheduling algorithms. The port priorities are labeled as CoS0, CoS1... CoS7. The DiffServ function can be implemented on Port Priority, DSCP Priority, 802.1P/CoS Mapping and Schedule Mode pages. 11.1.1 Port Priority On this page you can configure the port priority.
