You can use CAR, but it seems rather inefficient to do so when the ATM
interface will do it in hardware.
You don't need to take down the PVC and recreate it to change the cell
rate. Use the new style config, something like this:
interface ATM2/0.8 point-to-point
ip address 10.20.30.40 255.255.255.0
pvc 2/33
vbr-nrt 1140 1130 20
encapsulation aal5snap
Then you can change the cell rate quickly and efficiently without taking
down the PVC. You will probably drop a *little* traffic as the hardware
cell rate is changed - but not much.
