Creating a DSCP Color Map

You can create a DSCP color map to outline the differentiated services codepoint (DSCP) mappings to the appropriate color mapping

(green, yellow, red) for the input traffic. The system uses this information to classify input traffic on an interface based on the DSCP value

of each packet and assigns it an initial drop precedence of green, yellow, or red

The default setting for each DSCP value (0-63) is green (low drop precedence). The DSCP color map allows you to set the number of

specific DSCP values to yellow or red. Traffic marked as yellow delivers traffic to the egress interface, which will either transmit or drop the

packet based on configured queuing behavior. Traffic marked as red (high drop precedence) is dropped.

Important Points to Remember

All DSCP values that are not specified as yellow or red are colored green (low drop precedence).

A DSCP value cannot be in both the yellow and red lists. Setting the red or yellow list with any DSCP value that is already in the other

list results in an error and no update to that DSCP list is made.

Each color map can only have one list of DSCP values for each color; any DSCP values previously listed for that color that are not in the

new DSCP list are colored green.

If you configured a DSCP color map on an interface that does not exist or you delete a DSCP color map that is configured on an

interface, that interface uses an all green color policy.
