5.4 Configuring Port Priority Trust Mode

You can configure the switch to trust the DSCP precedence of the received packets. In
this case, the switch searches the dscp-dot1p/dp/dscp mapping table for the
corresponding precedence according to the DSCP precedence of the packets and
marks the received packets with the precedence.
