The short answer is yes.
Realize this: a map-class can be applied at three different levels: phy int,
sub int, and or the dlci.
If want to have different paramters at each level which you can, you have to
creat different map-classes. Also, note that a map-class applied at a lower
level supercedes the map-class that would otherwise be inherited from a
higher level.
Another to remember is that to apply a map-class to a DLCI, the class
command is used from the DLCI config mode but to apply a map-class to a
sub-int or phy int, the class frame relay <name> command is used.
And, if all that weren't enough, you can combine map-class with class-maps
which you actually have to do if you need to configure LLQ or WFQ. It's
enough to turn my hair grey.
