
Example
To display HOL prevention state on the Switching Hub:
50.16. config dscp map

Description
This command is used to configure DSCP 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.
 Format
