Use a Round Robin scheme. The Round Robin scheme means all the priority has the
same privilege, the traffic is forward cyclic from highest to lowest.
Use a strict priority scheme. Packets with higher priority in the queue will always be
processed first, except that there is no packet with higher priority.
Use Weighted Round Robin scheme. This scheme allows users to assign new weight
ratio for each class. The 10 is the highest ratio. The ratio of each class is as below:
Wx
/ W0 + W1 + W2 + W3 + W4 + W5 + W6 + W7 (Total volume of Queue 0-7)
Port Setting
Priority column is to indicate default port priority value for untagged or priority-tagged
frames. When JetNet receives the frames, JetNet will attach the value to the CoS field of
the incoming VLAN-tagged packets. You can enable 0,1,2,3,4,5,6 or 7 to the port.
Default priority type is COS. The system will provide default COS-Queue table to which
you can refer for the next command.
After configuration, press Apply to enable the settings.

CoS-Queue Mapping
This page is to change CoS values to Physical Queue mapping table. Since the switch
fabric of JetNet only supports 8 physical queues, Lowest, Low, Middle and High. Users
should therefore assign how to map CoS value to the level of the physical queue.
After configuration, press Apply to enable the settings.
4.7.3
DSCP-Queue Mapping
This page is to change DSCP values to Physical Queue mapping table. Since the switch
fabric of JetNet only supports 8 physical queues. Users should therefore assign how to
map DSCP value to the level of the physical queue. In JetNet, users can freely change the
mapping table to follow the upper layer 3 switch or routers’ DSCP setting.
