set as 0 are in the SP group; other queues, with none-zero weight value, belong to the WRR

group and the weight value can be customized, ranging from 0 to 127. In this way, when

scheduling queues, the switch allows TC7 and zero-weight-value queue to occupy the

whole bandwidth following the SP mode and the queues in the WRR group will take up the

bandwidth according to their ratio.

4. Equ-Mode: Equal-Mode. In this mode, all the queues occupy the bandwidth equally. The

weight value ratio of all the queues is 1:1:1:1:1:1:1:1.

Note:

In SP + WRR mode, TC7 and the queue with its weight value set as 0 are in the SP group.

The QoS module is mainly for traffic control and priority configuration, including three

submenus: DiffServ, Bandwidth Control and Voice VLAN.

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, Schedule Mode, 802.1P Priority

and DSCP Priority pages.

11.1.1 Port Priority

On this page you can configure the port priority.
