5.3 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.
5.3.1 Configuration Prerequisites
The port priority of the port is determined.
5.3.2 Configuration Procedure
Follow these steps to configure port priority:
