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.

Configuring the Port Priority

Use the command...
qos map-table { dot1p-dp |
dot1p-lp | dscp-dot1p |
