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 choosing 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. To view this window click, QoS > QoS Output Scheduling.
Figure 9- 4. QoS Output Scheduling window
The following values may be assigned 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.
