DSCP Color Map Commands
The DSCP color map allows you to set the number of specic DSCP values to yellow or red. Trac marked as yellow delivers trac
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.
Trac marked as red (high drop precedence) is dropped.
dscp
Sets the number of specic DSCP values for a color map prole to yellow or red.
Syntax
dscp {yellow | red} [list-dscp-values]
To remove a color policy map prole, use the no dscp {yellow | red} [dscp-list] command.
Parameters
Yellow Enter the yellow keyword. Trac marked as yellow delivers trac 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. Trac marked as red is dropped.
dscp-list Enter a list of IP DSCP values. The dscp-list parameter species the full list of IP
DSCP value(s) for the specied 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.
Defaults None
Command Modes CONFIG-COLOR-MAP

Usage Information If the specied color-map does not exist, the Diserv 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 specic DSCP values to yellow or red.
Important Points to Remember
• All DSCP values that are not specied 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.
