The QoS module is mainly for traffic control and priority configuration, including two submenus:
DiffServ and Bandwidth Control.

9.1 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, Schedule Mode, 802.1P Priority and
