5.11 QoS (Quality of Service) Configuration
The switch provides the following powerful QoS functions:
Per Port Priority
VLAN Tag Priority
IP TOS Classification
IP TCP/UDP Port Classification
IP DIffServe Classification
With QoS configurations, one setting is
Default Class
. When you set one of the five QoS
functions listed above, packets that do not belong to this QoS setting are viewed as
Default
Class
.
For example, if you set QoS function as VLAN Tag Priority mode, and then choose Default
Class as High, the priority of the packets with no tag will be considered as High priority. The
initial value of the Default Class is High.

Function name:
Per Port Priority
Function description:
QoS priority can be assigned, including High and Low for each port. For example, if IP packets from
Port 2 and Port 3 are transmitted at the speed of 1Gbps to Port 1, and the Class of Port 2 is set as
High and Port 3 is set as Low, then the packets of Port 3 will be dropped when the congestion
happens because Port 2 has a higher precedence of transmitting packets.
Parameter description:
Port No:
Choose the port 1~16 (24) respectively with Priority Class on Per Port Priority function.
