Once you have assigned a priority to the port groups on the Switch, you can then assign this Cl ass to each of the 7
levels of 802.1p priorities. Click Apply to set your changes.
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 ho w network traffic in lower priority queues are
affected. Changes in scheduling may result in unacceptable le vels of p ack et loss or significant transm ission delays. If
you choose to customize this setting, it is important to monitor network perf ormance, especia lly during pea k demand,
as bottlenecks can quickly develop if the QoS settings are not suitable.
