If you have the following:
int f0/1
mls qos cos 1
mls qos trust cos
The packets will retain their cos values, and the packets that are not
marked with cos, will have their cos value set to 1.
Now when you enter the following:
int f0/1
mls qos cos override
The override command will replace the "mls qos trust cos" command and it
will set the cos value of all packets (Marked or unmarked) to 1.
