2.3.4.1 CoS Mapping
Fig. 2.11
The switch can classify traffic based on a valid 802.1p (CoS) priority tag. These options
allow users to map CoS to the different priority queues, Fig. 2.11.
The default queue weighting is assigned as follow:
Q0 = 2 packets (Lowest priority)
Q1 = 1 packets (Low priority)
Q2 = 4 packets (Median priority)
Q3 = 8 packets (High priority)
For example, Q3 has the highest priority, and it carries 8 packets, while Q0 has the lowest
priority, and it carries 2 packets. When CoS 6 is assigned to Q3, it has the highest priority.
When Co1 is assigned to Q0, it has the lowest priority. For CoS explanations, please refer
to page 14.
