 want to make sure i have this correct:

lets say a 3560 switch here:
mls qos is enabled, nothing else.

packet comes in at cos 5.. it will get rewritten to 0. The reason it is 0 is
because the mls qos cos 0 command which is default. If i change this command to
mls qos cos 1 then all packets would be cos 1. Correct?

Adding to above scenario. If i do mls qos trust cos.. all cos packets coming in
at 5 will remain at 5. All packets coming in unmarked will get changed to cos
1. Is this correct?

Building on that. If i now do mls qos override. ALL Packets will get changed to
cos 1.

Am i wrong in any of my above understanding?
