6.20.1 QoS Policy and Priority Type
QoS Policy interface
 QoS Policy: Select the QoS policy rule.
 Using the 8,4,2,1 weight fair queue scheme: The switch will follow 8:4:2:1
rate to process priority queue from high to lowest queue. For example, while the
system is processing, 1 frame of the lowest queue, 2 frames of the low queue, 4
frames of the middle queue, and 8 frames of the high queue will be processed
in accordance with the 8,4,2,1 policy rule.
 Use a strict priority scheme: Always the higher queue will be processed first,
except the higher queue is empty.
 Priority Type: There are 5 priority type selections available—Port-based, TOS
only, COS only, TOS first, and COS first. Disable means no priority type is
selected.
 Select button to make the settings effective.
