Because you may have the ability to use the link speed all the way up to the
frame switch. So if you have a CIR of 256k, you will have an interface of a
T-1 and can use that whole T-1 to the FR switch. Then you might want to set
CIR to interface speed and mincir to actual cir. Then, if the switch does
not drop or mark your packets as DE, you can use the full interface until
and unless you get DE then you will drop down to mincir.
This is one reason I can think of.
