Chapter 2 Catalyst 3560 Switch Cisco IOS Commands mls qos srr-queue input dscp-map Usage Guidelines The DSCP assigned at the ingress port selects an ingress or egress queue and threshold. The drop-threshold percentage for threshold 3 is predefined. It is set to the queue-full state. You can assign two weighted tail-drop (WTD) threshold percentages to an ingress queue by using the mls qos srr-queue input threshold global configuration command. You can map each DSCP value to a different queue and threshold combination, allowing the frame to follow different behavior. You can map up to eight DSCP values per command. Examples This example shows how to map DSCP values 0 to 6 to ingress queue 1 and to threshold 1 with a drop threshold of 50 percent. It maps DSCP values 20 to 26 to ingress queue 1 and to threshold 2 with a drop threshold of 70 percent: Switch(config)# mls qos srr-queue input dscp-map queue 1 threshold 1 0 1 2 3 4 5 6 Switch(config)# mls qos srr-queue input dscp-map queue 1 threshold 2 20 21 22 23 24 25 26 Switch(config)# mls qos srr-queue input threshold 1 50 70 You can verify your settings by entering the show mls qos maps privileged EXEC command.
