DGS-3312SR Gigabit Layer 3 Switch
QoS Output Scheduling Configuration
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 priority queues are
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.

Use the Scheduling Mechanism drop-down menu to select between a RoundRobin and a Strict mechanism for empting the
priority queues.
Click Apply to let your changes take effect.
Traffic Segmentation
Traffic segmentation is used to limit traffic flow from a single port to a group of ports on either a single Switch (in
standalone mode) or a group of ports on another Switch in a Switch stack. This method of segmenting the flow of traffic is
similar to using VLANs to limit traffic, but is more restrictive. It provides a method of directing traffic that does not
increase the overhead of the Master Switch CPU.
