See Honoring DSCP Values on Ingress Packets for moreinformation.• Assign a WRED profile to either yellow or green traffic.QOS-POLICY-OUT modewredDisplaying Default and Configured WREDProfilesTo display the default and configured WRED profiles, use the following command.• Display default and configured WRED profiles and their threshold values.EXEC modeshow qos wred-profileExample of the show qos wred-profile CommandDell#show qos wred-profileWred-profile-name min-threshold max-threshold max-drop-ratewred_drop 0 0 100wred_teng_y 594 5941 100wred_teng_g 594 5941 50wred_fortyg_y 594 5941 50wred_fortyg_g 594 5941 25wred_oneg_y_pe 154 1538 100wred_oneg_g_pe 154 1538 50wred_teng_y_pe 154 1538 50wred_teng_g_pe 154 1538 25Quality of Service (QoS) 928
