Chapter 4 Priority Mapping Configuration
Commands
4-4
Parameters
priority-value: Port priority to be configured. This argument is in the range 0 to 7.
Description
Use the qos priority command to set the port priority for a port.
Use the undo qos priority command to restore the default port priority.
By default, the port priority is 0.
Note that, if a port receives packets without an 802.1q tag, the switch takes the priority
of the receiving port as the 802.1p precedence of the packets and then searches the
dot1p-dp/lp mapping table for the local/drop precedence for the packets according to
the priority of the receiving port.
Examples
# Set the port priority of Ethernet2/0/1 port to 2.
<Sysname> system-view
