Port Setting
Priority
Indicate the default port priority value for untagged or
priority-tagged frames. When the switch receives the frames, it
will assign the priority to the frames. You can enable 0, 1, 2 or 3
to the port. The priority is directly mapping to queue id, queue 3 is
the highest priority queue.
Trust Mode
This indicates Queue Mapping types for you to select.
CoS Only
Port priority will only follow CoS-Queue Mapping that
you have assigned.
DSCP Only Port priority will only follow DSCP-Queue Mapping
that you have assigned.
CoS first
Port priority will follow CoS-Queue Mapping first, and
then DSCP-Queue Mapping rule.
DSCP first Port priority will follow DSCP-Queue Mapping first,
and then CoS-Queue Mapping rule.
Port Based The port priority will follow the queue priority that you
have assigned.
The default priority type is CoS Only. The system will provide a
default CoS-Queue table that you can refer to for the next
command.
After configuring, click the Apply button to enable the settings.
3.6.2.
CoS-Queue Mapping
This area is where you can set CoS values to the Physical Queue mapping table.
Since the switch supports 4 physical queues (Lowest, Low, Middle and High),
each CoS value should be assigned to a level of the physical queue.
You can easily assign the mapping table or follow suggestions from the 802.1p
standard.
Korenix
uses 802.p standards by default. You will find that the CoS
values 1 and 2 are mapped to physical Queue 0 (lowest queue). CoS values 0
and 3 are mapped to physical Queue 1, (low/normal physical queue), CoS values
4 and 5 are mapped to physical Queue 2 (middle physical queue), and CoS
values 6 and 7 are mapped to physical Queue 3 (highest physical queue).
