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, as 
the system processes, 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 higher queue will be processed first, 

except higher queue is empty. 

•  Priority Type: there are 5 priority type selections available. Disable means no 

    priority type is selected. 

•  Port-base: the port priority will follow the Port-base that you have assigned – High, 

    middle, low, or lowest. 

¾

  COS only: the port priority will only follow the COS priority that you have 

assigned. 

¾

  TOS only: the port priority will only follow the TOS priority that you have 

assigned. 

¾

  COS first: the port priority will follow the COS priority first, and then other 

priority rule. 

¾

  TOS first: the port priority will follow the TOS priority first, and the other 

priority rule.
