Table 5 Priority mapping results of not trusting packet priority (when the default
dot1p-lp priority mapping table is used)
Port priority Local precedence Queue ID
0 (default) 2 2
1 0 0
2 1 1
3 3 3
4 4 4
5 5 5
6 6 6

The priority mapping process varies with priority trust mode. 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 procedure 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.
