Dears,


I am wondering if I need config both cos-map and dscp-map for output queue, I have added the cos-map cmd as following:


SW(config)#mls qos srr−queue output cos−map queue 1 threshold 1 5


should I config also:


SW(config)#mls qos srr−queue output dscp−map queue 1 threshold 1 40 41 42 43 44 45 46 47


or the dscp-map will generate automatically?



Thanks

No, DSCP-output-q map will not change. But if you trust CoS you may change your DSCP using cos-dcp map.
