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
Click on
Configure
next to the desired QoS function. Once you have set the configurations,
remember to click on
Apply
to save the settings.
With QoS configurations, the
Default Class
is either set to
high
or
low
. 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.
Figure 5.17 – QoS Configuration
The QoS functions listed in Figure 5.17 are listed below.
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.
