5-16 config dscp map
Description
This command is used to configure DHCP mapping. The mapping of DSCP to priority will be used to
determine the priority of the packet (which will be then used to determine the scheduling queue) when
the port is in DSCP trust state.
The mapping of DSCP to color will be used to determine the initial color of the packet when the
policing function of the packet is color aware and the packet is DSCP-trusted.
The DSCP-to-DSCP mapping is used in the swap of DSCP of the packet when the packet is ingresses
to the port. The remaining processing of the packet will base on the new DSCP. By default, the DSCP
is mapped to the same DSCP.
These DSCP mapping will take effect at the same time when IP packet ingress from a DSCP-trusted
port.
