Port Setting
CoS
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.
Trust Mode
is to indicate Queue Mapping types for you to select.

4.6.2 CoS-Queue
Mapping
This page is to change CoS values to Physical Queue mapping table. Since the switch
fabric of JetNet only supports 4 physical queues, Lowest, Low, Middle and High. Users
should therefore assign how to map CoS value to the level of the physical queue.
In JetNet, users can freely assign the mapping table or follow the suggestion of the 802.1p
standard. Korenix uses 802.p suggestion as default values. You can find CoS values 1 and
2 are mapped to physical Queue 0, the lowest queue. CoS values 0 and 3 are mapped to
physical Queue 1, the low/normal physical queue. CoS values 4 and 5 are mapped to
physical Queue 2, the middle physical queue. CoS values 6 and 7 are mapped to physical
Queue 3, the high physical queue.
After configuration, press

to enable the settings.
