Precedence of Priorities
If multiple priorities are associated with a frame or packet, the
switch classifies the frame or packet according to the priority of
highest precedence. See Table 6-138 for the precedence of each
priority.
The switch then assigns the frame or packet to the appropriate
priority queue based on the priority of the frames.
