Configuration example# Configure to trust port priority on GigabitEthernet 1/0/1 and set the priority ofGigabitEthernet 1/0/1 to 7. system-view[Sysname] interface GigabitEthernet1/0/1[Sysname-GigabitEthernet1/0/1] priority 7# Configure to trust packet priority on GigabitEthernet 1/0/1. system-view[Sysname] interface GigabitEthernet1/0/1[Sysname-GigabitEthernet1/0/1] priority trust1.4.2 Configuring the Mapping between 802.1p Priority and LocalPrecedenceWhen the default mapping between 802.1p priority and local precedence cannot satisfyyour requirements, you can modify the mapping at the CLI, thus modifying the mappingbetween 802.1p priority and the output queues and assigning packets with differentpriorities to the corresponding output queues.
