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
received packets, and then marks the received packets with the corresponding local precedence and
drop precedence.
Port priority is in the range 0 to 7. You can set the port priority as required.
