Configuring the Port Priority
By default, if a port receives packets without 802.1q tags, the switch takes the priority of the receiving
port as the 802.1p precedence of the received packets, searches the dot1p-lp/dp mapping table for the
corresponding local precedence and drop precedence according to the 802.1p precedence of the
