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.
