Chapter 2 Catalyst 3560 Switch Cisco IOS Commands mls qos srr-queue input cos-map Usage Guidelines The CoS 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 CoS value to a different queue and threshold combination, allowing the frame to follow different behavior. Examples This example shows how to map CoS values 0 to 3 to ingress queue 1 and to threshold ID 1 with a drop threshold of 50 percent. It maps CoS values 4 and 5 to ingress queue 1 and to threshold ID 2 with a drop threshold of 70 percent: Switch(config)# mls qos srr-queue input cos-map queue 1 threshold 1 0 1 2 3 Switch(config)# mls qos srr-queue input cos-map queue 1 threshold 2 4 5 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.

Allocates the buffers between the ingress queues. Maps Differentiated Services Code Point (DSCP) values to an ingress queue or maps DSCP values to a queue and to a threshold ID. Configures the ingress priority queue and guarantees bandwidth. Assigns WTD threshold percentages to an ingress queue.
