Is there any difference between these two commands:
set ip dscp and set dscp
match ip dscp and set dscp
It appears that you can mark using one ore the other but not both, but match using both.
match dscp af11
match ip dscp af11
set dscp af11
set ip dscp af11
Effective with Release 12.2(13)T, the set ip dscp command is replaced by the set dscp command.
However, the set dscp command cannot be used with the set precedence command to mark the same packet. The two values, DSCP and precedence, are mutually exclusive. A packet can have one value or the other, but not both.
