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 the priority queue from the highest to
the lowest queue. For example, when 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.
¾ Use the strict priority scheme: The highest queue will always
processed first.
Priority Type: there are five priority selections available.
Port-base: the port priority will follow the assigned Port-base – High,
middle, low, or lowest.
¾ COS Only: the port priority will only follow the COS priority
assigned.
¾ TOS only: the port priority will only follow the TOS priority
assigned.
¾ COS first: the port priority will follow the COS priority first, and
then the other priority rule.
¾ TOS first: the port priority will follow the TOS priority first, and then
the other priority rule.
