After some googleing, I soon found there is little info on how to use an interface range macro.

You need to define the interface range:
Switch_3550(config)#define interface-range CCIE fa 0/17 – 18

Then you can use it:
Switch_3550(config)#int range macro CCIE

I think the syntax to use it is a little weird; you might as well type in the full command as it is the same length in most cases.
