QoS Output Scheduling
QoS can be customized by changing the output scheduling used for the hardware queues in the Switch. As with any changes
to QoS implementation, careful consideration should be given to how network traffic in lower priority queues 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 screen shown below.
Figure 6- 44. QoS Output Scheduling Configuration 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
queue 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.
NOTE: Entering a 0 for the Max Packets field in the QoS Output Scheduling
Configuration window above will create a Combination Queue. For more
information on implementation of this feature, see the next section, Configuring
the Combination Queue.
