mls qos srr-queue input dscp-map
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.
