QoS Configuration
Here you can configure Qos policy and priority setting, per port priority setting, COS and TOS setting.
QoS Policy and Priority Type
• Qos Policy: Select the QoS policy rule.
¾ Use an 8,4,2,1 weighted fair queuing scheme: The switch will follow 8:4:2:1 rate to process
priority queue from High to lowest queue. For example, while the system 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 at the same time in accordance with the 8,4,2,1 policy rule.
¾ Use a strict priority scheme: Always the higher queue will be processed first, except the
higher queue is empty.
¾ 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.
• Click Apply to make the settings effective.
