Qos Output Scheduling - D-Link DES-6500 User Manual

D-Link DES-6500 Layer 3 Stackable Gigabit Ethernet Switch

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 priority queues 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.

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.
Note: The settings you assign to the queues, numbers 0-7,
represent the IEEE 802.1p priority tag number. Do not
confuse these settings with port numbers.
