QoS
In QoS section, you can configure the QoS settings of each port.
Oos Policy
You can select the Qos policy rule.
Using an 8,4,2,1 weighted fair queuing scheme : the JetNet will follow 8:4:2:1 rate to process
the packets in a queue from the highest priority to the lowest. For example, the system will
process 8 packets with the highest priority in the queue, 4 with middle priority, 2 with low priority,
and 1 with the lowest priority at the same time.
Use the strict priority scheme : packets with higher priority in the queue will always be
processed first, except that there is no packet with higher priority.
Priority Type
Each port has 5 priority types for you to select.
Port-based: the port priority will follow the default port priority that you have assigned – High,
middle, low, or the 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 then other priority rule.
Default Priority Type
This is to decide the default priority of each port.
