3-5. QoS(Quality of Service) Configuration
The
switch
offers powerful 5 kinds of QoS functions. There are Per Port
Priority that you can assign each port to different precedence, VLAN Tag priority
that can make precedence of 8 priorities, IP TOS Classification, IP TCP/UDP Port
Classification and IP DiffServe Classification.
In Quality of Service (QoS) Configuration, there is one option named” Default
Class”. As you had selected one of the five QoS functions, then some packets that
did not belong to this QoS setting would be viewed as Default Class. For instance, if
you set QoS function as VLAN Tag Priority mode, and then choose Default Class as
High, finally, the priority of the packets with no tag will be considered as High priority
precedence. The initial value of the Default Class is High.
