Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

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.

To create a DSCP color map:

1. Create the color-aware map QoS DSCP color map.

   CONFIGURATION mode

   qos dscp-color-map color-map-name

2. Create the color aware map profile.

   DSCP-COLOR-MAP

   dscp {yellow | red} { list-dscp-values}

3. Apply the map profile to the interface.

   CONFIG-INTERFACE mode

   qos dscp-color-policy color-map-name  

Example: Create a DSCP Color Map

The following example creates a DSCP color map profile, color-awareness policy, and applies it to interface te 1/11.

Create the DSCP color map profile, bat-enclave-map, with a yellow drop precedence , and set the DSCP values to 9,10,11,13,15,16

Dell(conf)# qos dscp-color-map bat-enclave-map
                              Dell(conf-dscp-color-map)# dscp yellow 9,10,11,13,15,16 
                              Dell (conf-dscp-color-map)# exit
                              
                           

Assign the color map, bat-enclave-map to interface .
