1.4 Setting to Use the Port Priority or Packet Priority

By default, the switch replaces the 802.1p priority of the received packet with the
priority of the inbound interface, and then assigns local precedence for the packet
according to the priority. In this case, you can set the port priority.
In addition, you can specify the switch to use the packet priority.
