can anyone tell me why I would need to use the match any, or match all statements in my class map, I have only normally used the match access list command.
thanks

If you do this-
class-map CS
match access-group 101
then in fact you are using the "match-all" anyway. Basically when you specify "class-map CS" that is shorthand for "class-map match-all CS". You don't need to specify it because it is the default but if you wanted to specify match-any then you would need to configure "class-map match-any CS".
Now if you are matching against a single access-list it doesn't really matter which you use. But lets say you have this -
class-map CS
match access-group 101
match ip dscp ef
now it makes a big difference which you specify. If you specify match-all then the packet must match the acl 101 and also have the DSCP value of 46 which is EF.
If you specify match-any then the packet only has to match one of the criteria ie. it only needs to either match the acl 101 or have a DSCP value of 46.
So the match-all/match-any gives you more flexibility when there are multiple criteria to match a packet against.
