The priority mapping process varies with the priority trust modes. For more information, see the
subsequent section.
Priority mapping process
On receiving an Ethernet packet on a port, the switch marks the scheduling priorities (local precedence
and drop precedence) for the Ethernet packet. This process is done according to the priority trust mode
of the receiving port and the 802.1q tagging status of the packet, as shown in
Figure 4
.
