DGS-3024 Gigabit Ethernet Switch Manual
The Scheduling Mechanism has the following parameters.
Parameter Description
Strict The highest class of service is the first to process traffic. That is, the highest class of service
will finish before other queues empty.
RoundRobin Use the weighted round-robin ( WRR ) algorithm to handle packets in an even distribution in
priority classes of service.
Click Apply to make your changes take effect.
NOTE : The settings you assign to the queues, numbers 0-7, represent the
IEEE 802.1p priority tag number. Do not confuse these settings with port
numbers.
QoS Output Scheduling
QoS can be customized by changing the output scheduling used for the hardware classes of service in the Switch. As with any
changes to QoS implementation, careful consideration should be given to how network traffic in lower priority classes of service
is affected. Changes in scheduling may result in unacceptable levels of packet loss or significant transmission delay. If you choose
to customize this setting, it is important to monitor network performance, especially during peak demand, as bottlenecks can
quickly develop if the QoS settings are not suitable. In the
Configuration folder open the QoS folder and click QoS Output
Scheduling , to view the window shown below:
Figure 7- 47. QoS Output Scheduling window
You may assign the following values to the QoS classes to set the scheduling.
Parameter Description
Max. Packets
Specifies the maximum number of packets the above specified hardware priority class of
service will be allowed to transmit before allowing the next lowest priority queue to transmit its
packets. A value between
0 and 15 can be specified.
Click Apply to implement changes made.
