QoS Configuration
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.
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.
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.
COS only: the port priority will only follow the COS priority that you have assigned.
TOS only: the port priority will only follow the TOS priority that you have assigned.
COS first: the port priority will follow the COS priority first, and then other priority rule.
TOS first: the port priority will follow the TOS priority first, and the other priority rule.
