xStack DGS/DXS-3300 Series Layer 3 Stackable Gigabit Ethernet Switch User Manual 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. In the Configuration folder open the QoS folder and click QoS Output Scheduling , to view the screen shown below. Figure 6- 48. QoS Output Scheduling Configuration 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. 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. 91
