Queue Scheduling
You can select the Queue Scheduling rule as follows:
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 the switch receives the frames, the switch 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.
4.8.2 CoS-Queue Mapping
This page is to change CoS values to Physical Queue mapping table. The switch
supports eight physical queues and the users should therefore assign how to map
CoS value to the level of the physical queue.
After configuration, press Apply to enable the settings.
