DGS-3700-12/DGS-3700-12G Series Layer 2 Gigabit Ethernet Switch User Manual

802.1p User Priority

The Switch allows the assignment of a user priority to each of the 802.1p priorities.

Once you have assigned a priority to the port groups on the Switch, you can then assign this Class to each of the 7 levels of 802.1p priorities. Click Apply to set your changes.

QoS Scheduling Mechanism

Changing the output scheduling used for the hardware queues in the Switch can customize QoS. 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 delays. 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.
