S4820T and, S5000.When you assign a percentage to one queue, note that this change also affects the amount of bandwidththat is allocated to other queues. Therefore, whenever you are allocating bandwidth to one queue, DellNetworking 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%.bandwidth-percentageSpecifying WRED Drop PrecedenceYou can configure the WRED drop precedence in an output QoS policy.• Specify a WRED profile to yellow and/or green traffic.QOS-POLICY-OUT modewredFor more information, refer to Applying a WRED Profile to Traffic.DSCP Color MapsThis section describes how to configure color maps and how to display the color map and color mapconfiguration.This sections consists of the following topics:• Creating a DSCP Color Map• Displaying Color Maps• Display Color Map ConfigurationCreating a DSCP Color MapYou can create a DSCP color map to outline the differentiated services codepoint (DSCP) mappings tothe appropriate color mapping (green, yellow, red) for the input traffic. The system uses this informationto classify input traffic on an interface based on the DSCP value of each packet and assigns it an initialdrop precedence of green, yellow, or redThe default setting for each DSCP value (0-63) is green (low drop precedence). The DSCP color mapallows you to set the number of specific DSCP values to yellow or red. Traffic marked as yellow deliversQuality of Service (QoS) 717
