Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Color traffic

You can select a traffic flow and mark it with a color. Color the traffic flow based on:

• Metering. See Policing traffic.
• Default trust. See Trust-based classification.
• DSCP, ECN capable traffic (ECT), or non-ECT capable traffic. Use the set color command to color traffic based on DSCP, ECN capable, or non-ECN capable traffic.

Traffic policing and traffic coloring using DSCP values are mutually exclusive. You cannot configure both at the same time. Policing and marking using DSCP values take precedence over trust-based classification. Trust-based classification has the lowest priority.

Color traffic based on DSCP, ECT, or non-ECT

1. Create a QoS type class-map to match the traffic flow.

   OS10(config)# class-map type qos example-cmap-dscp-3-ect
   OS10(config-cmap-qos)# match ip dscp 3
   

2. Create a QoS type policy-map to color the traffic flow.

   OS10(config)# policy-map type qos example-pmap-ect-color
   OS10(config-pmap-qos)# class example-cmap-dscp-3-ect
   OS10(config-pmap-c-qos)# set qos-group 3
   OS10(config-pmap-c-qos)# set color yellow
