QoS Scheduling Mechanism

Changing the output scheduling used for the hardware queues in the Switch can customize QoS. As with any changes
to QoS implementation, careful consideration should be given to how network traffic in lower priority queues are
affected. Changes in scheduling may result in unacceptable levels of packet loss or significant transmission delays. 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.

Description
Select the unit to configure.
Enter the port or port list to configure.
Select the Class ID, from 0 to 6 to configure for the QoS parameters.
Strict – Select to have the queue always in the strict mode.
Weight – Use the weighted round-robin (WRR) algorithm to handle packets in an even
distribution in priority classes of service.
