Do not configure 802.1p priority marking and local precedence marking for the same traffic.
With 802.1p priority marking, the new 802.1p priority will be mapped to a local precedence
automatically. If local precedence marking is also configured, there will be two local
precedence values for the traffic, resulting in conflict. In this case, the device will display
an error prompt.
Examples
# Set the 802.1p priority to 1 for the packets received on any ports in VLAN 2 and destined
to MAC address 000F-E200-1234.
