Parameter Description
RoundRobin Use the weighted round-robin (
WRR
) algorithm to handle packets in an even
distribution in priority classes of service.

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
Administration
folder open the
QoS
folder and click
QoS Output Scheduling
, to view the window shown below:
Note: In order to configure QoS Output Scheduling it needs to be in the Round Robin parameter.
Figure 9- 7. QoS Output Scheduling Window
You may assign the following values to the QoS classes to set the scheduling.
Parameter Description
Weight 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.
