CoS Output Scheduling
CoS can be customized by changing the output scheduling used for the hardware classes of service in the Switch. As with
any changes to CoS 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 CoS settings are not suitable. In the CoS folder, click CoS Output
Scheduling, to view the screen shown below.
Figure 8- 6. CoS Output Scheduling Configuration window
You may assign the following values to the CoS 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 1 and 55 can be specified.
Click Apply to implement changes made.
