Here you can configure Qos policy and priority setting, per port priority setting, COS and TOS setting. 

 
 

•  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.
