NOTE: In Dell Networking OS we support 8 data queues in S4048, S6000, Z9500 and 4 data queues
in S3048, S4810. S4820T and, S5000.
When you assign a percentage to one queue, note that this change also affects the amount of bandwidth
that is allocated to other queues. Therefore, whenever you are allocating bandwidth to one queue, Dell
Networking recommends evaluating your bandwidth requirements for all other queues as well.
• Assign each queue a bandwidth percentage ranging from 1 to 100%, in increments of 1%.

DSCP Color Maps
This section describes how to configure color maps and how to display the color map and color map
configuration.
This sections consists of the following topics:
• Creating a DSCP Color Map
• Displaying Color Maps
• Display Color Map Configuration
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
