C.3.4 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.
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.
