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.
