Parameter
None
Description
Use the priority trust command to configure the switch to trust the 802.1p priority of a packet.
Use the undo priority command to restore the default settings.
By default, port priority is trusted.
In port priority trusted mode, when receiving an 802.1q tagged packet, the switch replaces the 802.1p
priority of the packet with the port priority, searches for the local precedence corresponding to the port
priority of the receiving port in the 802.1p-to-local precedence mapping table, and assigns the local
precedence to the packet.
You can use the priority trust command to configure the switch to trust the 802.1p precedence of the
received packets. In this case, the priority of the receiving port is not used as the 802.1p precedence.
Example
# Configure the switch to trust the 802.1p precedence of the received packets.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] priority trust
