12.2 DiffServ

Differentiated Services (DiffServ) feature allows traffic to be classified into streams and given
certain QoS treatment in accordance with defined per-hop behaviors.
Packets are classified based on the criteria which is defined by a class. Policy attributes may be
defined on a per-class instance basis, and it is these attributes that are applied when a match
occurs. A policy can contain multiples classes. When the policy is active, the actions taken
depend on which class matches the packet. The policy can be added to the ports after service
configuration.
The DiffServ function can be implemented on Global, Class Summary, Class Config, Policy
Summary, Policy Config and Servive Config pages.

12.2.1 Global

On this page you can configure the DiffServ Admin Mode and view the DiffServ Entry Table.
Strict-Priority + Weight Round Robin Mode. In this mode, this
switch provides two scheduling groups, SP group and WRR
group. Queues in SP group and WRR group are scheduled
strictly based on strict-priority mode while the queues inside
WRR group follow the WRR mode. In SP+WRR mode, TC6 is in
the SP group; TC0, TC1, TC2 to TC5 belong to the WRR group
and the weight value ratio of TC0, TC1, TC2 to TC5 is 1:2:3:4:5:6.
In this way, when scheduling queues, the switch allows TC6 to
occupy the whole bandwidth following the SP mode and the
TC0, TC1, TC2 to TC6 in the WRR group will take up the
bandwidth according to their ratio 1:2:3:4:5:6:7.
Set Minimum guaranteed bandwidth for TC0-TC6. Valid
bandwidth range is 0% to 100%. Total queue minimum
bandwidth value is 100%.
