Click Apply to set the bandwidth control for the selected ports. Results of configured Bandwidth Settings will be displayed
in the Port Bandwidth Table.

QoS Scheduling Mechanism

This drop-down menu allows you to select between a Weight Fair and a Strict mechanism for emptying the priority
queues. In the Configuration folder, open the QoS folder and click QoS Scheduling Mechanism, to view the window
shown below.
The Scheduling Mechanism has the following parameters.

Click Apply to let your changes take effect.

QoS Output Scheduling

QoS can be customized by changing the output scheduling used for the hardware queues in the Switch. As with any
changes to QoS implementation, careful consideration should be given to how network traffic in lower classes of services
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 QoS settings are not suitable. In the Configuration folder open the QoS folder and
click QoS Output Scheduling, to view the window shown below.

transmitting, or both receiving and transmitting packets.
This drop-down menu allows you to specify that the selected port will have no
bandwidth limit. Enabled disables the limit.
This field allows you to enter the data rate, in Mbit/s, that will be the limit for the
selected port.

Description
The highest queue is the first to process traffic. That is, the highest queue will finish
before other queues empty.
Use the weighted round-robin (WRR) algorithm to handle packets in an even
distribution in priority queues.
