Configuring the Mapping between 802.1p Priority and Local Precedence
When the default mapping between 802.1p priority and local precedence cannot satisfy your
requirements, you can modify the mapping at the CLI, thus modifying the mapping between 802.1p
priority and the output queues and assigning packets with different priorities to the corresponding output
queues.
Note that, this is a global setting, not a per port setting. This is only recommended for advanced network
environments.
Configuration prerequisites
The mapping between 802.1p priority and local precedence has been determined.
Configuration procedure
Follow these steps to configure the mapping between 802.1p priority and local precedence:

Configuration example
z Configure the following mapping between 802.1p priority and local precedence: 0 to 2, 1 to 3, 2 to 4,
3 to 1, 4 to 7, 5 to 0, 6 to 5, and 7 to 6.
z Display the configuration.
