Actually, 12.0 supports both the new way (pvc blah 0/40) or the old way (atm
pvc....). Its 12.1 that only support the new way.

The atm pvc <vcd> <vpi> <vci> command is used in versions prior to 12.0 ie,
11.3 and before. If you are running 12.0 on your router you need to
configure your pvc's the other way.
The basic rules here are the same as they are for Frame Relay. You have
some exceptions.
LANE:
A multipoint subinterface MUST be used in LANE. Some things must be
configured on the main interface.
PVC
A subinterface could be used if you have multiple networks and need to
separate them. You may also be using LANE or CLIP or SVCs on the same
physical interface and you want to separate the networks running over these
technologies.
If you have a star topology in the cloud using the same subnet you will
probably stay on the main interface and then use a map list or specify the
mapping under the pvc.
SVCs
I would think that you would always stay on the main interface here unless
you were running separate subnets or were using separate methods of ATM like
Clip.
CLIP
Again, CLIP would be configured on the main interface unless you had
separate subnets to configure or were using other methods of transport like
LANE.
Anyone else have any additional ideas?

I have a question on ATM interfaces -
You can set up a PVC by one or two ways -
pvc <vpi> <vci> command
or
atm pvc <vcd> <vpi> <vci> command
can somebody provide me an explanation on when you would use either or...
also, for an atm interface, can somebody explain when you would use or not
use a sub interface.
thanks....
