queues will follow the weighted round-robin scheduling scheme.
Weight fair
Use the weighted round-robin (WRR) algorithm to handle packets in an even distribution in
priority classes of service.

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. To view this window click CoS > CoS Output Scheduling

You may assign the following values to the CoS classes to set the scheduling.
Parameter Description
Weights
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.
