Schedule Settings

QoS Output Scheduling Settings

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.
To view this window, click QoS > Schedule Settings > QoS Output Scheduling Settings, as shown below.
