D-Link DGS-3212SR Layer 2 Gigabit Ethernet Switch
Configuring 802.1p User Priority
The DGS-3212SR allows the assignment of a User Priority to each of the 802.1p priorities.
Figure 10-5. User Priority Configuration
Once you have assigned a priority to the port groups on the switch, you can then assign this Class to each of the
8 levels of 802.1p priorities.
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.
