Hi Group,

I have quick question: if I want to assign DSCP values to all frames
received on certain CAT 3550 ports, are the following two methods
equivalent? If not, what are the conditions one should be used instead
the other?

Method 1:

            Use "set dscp" under policy-map

Method 2:

            Modify mls qos cos-dscp map

Thank you very much
