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.
