QoS Scheduling Mechanism
This drop-down menu allows you to select between a Weight Fair and a Strict mechanism for emptying the classes of service. In the Configuration folder
open the
QoS folder and click QoS Scheduling Mechanism, to view the screen shown below.
Figure 6- 49. Scheduling Mechanism Configuration and QoS Scheduling Mechanism Table
The
Scheduling Mechanism has the following parameters.
Parameter Description
Strict
The highest queue is the first to process traffic.That is, the highest queue will finish before other queues empty.
Weight fair Use the weighted round-robin (WRR) algorithm to handle packets in an even distribution in priority queues.
Click
Apply to let your changes take effect.
Output Scheduling
QoS can be customized b
y changing the output scheduling used f
or the classes of ser
vice in the Switch.
As with any changes to QoS implementation, careful
consideration should be given to how network traffic in lower 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 QoS settings are not suitable. In the
Configuration folder open the QoS folder and click QoS Output Scheduling,
to view the screen shown below.
