Configuring a port to trust packet priority for priority
mapping
When you configure the trusted packet priority type on an interface, use the following priority trust
modes:
•
dot1p
—Uses the 802.1p priority of received packets for mapping.
•
dscp
—Uses the DSCP precedence of received IP packets for mapping.
