mls qos ssrr-queue meaning

[posemman]

Hi, can you help me.

May I know the meaning of below commands?

mls qos srr-queue output cos-map queue 3 threshold 1 4
mls qos srr-queue output cos-map queue 4 threshold 1 3
mls qos srr-queue output dscp-map queue 3 threshold 1 34
mls qos srr-queue output dscp-map queue 4 threshold 1 24 26
mls qos

In core switch 3850 how can I configure it?
