Traffic Prioritization | CoS-Queue Mapping Page
Use this page is to change the CoS values to Physical Queue mapping table. Since the switch fabric of the
WR7802-XT supports four physical queues,
Lowest
,
Low
,
Middle
, and
High
.
You should therefore assign how to map CoS value to the level of the physical queue. You can freely assign the
mapping table or follow the suggestion of the IEEE 802.1p standard.
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.

Port Settings
CoS
This column indicates the default port priority value for untagged or
priority-tagged frames. When the WR7802-XT receives the frames, it

You can select 0,1,2,3,4,5,6 or 7 for the port.
Trust Mode
Indicates the Queue Mapping types for you to select.
CoS Only
: Port priority only follows CoS-Queue Mapping that you have
assigned.
DSCP Only
: Port priority only follows DSCP-Queue Mapping that you
have assigned.
CoS first
: Port priority follows CoS-Queue Mapping first, and then the
DSCP-Queue Mapping rule. The default priority type is
CoS First
. The
system provides a default CoS-Queue table for which you can refer to the
next command.
