Some packets which did not belong to the selected QoS classifica-
tion method would be classified as Default Class.
[VLAN Tag Priority]
In VLAN-tagged packet, there are 3 bits belonging to priority.

1 0, 0 1 0, 1 0 0, 1 0 1, 1 1 0, 1 1 1. We can set High priority or Low
priority for each traffic class.

In a received IP packet, TOS field is used to classify the priority
class to which the packet belongs.
[

class to which the packet belongs.
