DSCP Color Map Commands
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 queue which will either transmit the packet if it has available bandwidth or drop the packet due to no ability
to send. Traffic marked as red (high drop precedence) is dropped.
dscp
Sets the number of specific DSCP values for a color map profile to yellow or red.
C9000 Series
Syntax
dscp {yellow | red} [list-dscp-values]
To remove a color policy map profile, use the no dscp {yellow | red} [dscp-list] command.
Parameters
Yellow Enter the yellow keyword. Traffic marked as yellow delivers traffic to the egress
queue which either transmits the packet if it has available bandwidth or drops the
packet due to no ability to send.
red Enter the red keyword. Traffic marked as red is dropped.
dscp-list Enter a list of IP DSCP values. The dscp-list parameter specifies the full list of IP
DSCP value(s) for the specified color. Each DSCP value in a list is separate values
by commas – no spaces (1,2,3) or indicates a list of values separated by a hyphen
(1-3). Range is 0 to 63.

Usage
Information
If the specified color-map does not exist, the Diffserv Manager (DSM) creates a color map and sets all
the DSCP values to green (low drop precedence).
The default setting for each DSCP value (0-63) is green (low drop precedence). This command allows
setting the number of specific DSCP values to yellow or red.
Important Points to Remember
● All DSCP values that are not specified as yellow or red are colored green.
● 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 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.
Example
Dell(conf-dscp-color-map)# dscp yellow 9,10,11,13,15,16
